The Schlage Encode Smart WiFi Deadbolt is the best smart lock for an Airbnb rental in the sub-300 bracket, because it is the only lock in this roundup that creates and deletes guest codes on its own when a booking changes. There is no separate keypad to buy, no gateway to pair, and no monthly fee stacked on top. If you want a cheaper option, the TEEHO TE001 gives you a self-deleting one-time PIN for a fraction of the outlay, and the ULTRALOQ Bolt SE adds fingerprint entry plus hub-free remote control in the middle of the range.
That budget framing matters more than it sounds. Most “smart lock” roundups quote the bare price of a deadbolt and stop there, but a rental lock is a system: lock, keypad, wireless bridge, and a year of batteries. Add the pieces a host actually needs and several popular models sail past the ceiling. Every pick below works as a complete guest-access setup without pushing you past the 300-dollar all-in limit, and I note the add-ons each one requires so you can budget honestly.
Our team spent six weeks cycling guest codes, cleaners’ codes, and contractor codes through ten locks across three property types: a coastal condo, an urban apartment, and a mountain cabin with unreliable internet. We measured install time, watched battery alerts at high turnover, and checked whether codes really expired after checkout. If you are still weighing keypad-only models, our keypad smart lock guide for Airbnb hosts covers that tier in detail.
One rule shaped everything below: a smart lock never replaces an onsite lockbox. Guests lock themselves out at 10pm often enough that a physical backup stays mandatory, no matter how good the app is.

Top 3 Picks for the Best Smart Locks for Airbnb Rentals Under 300 (October 2026)
Schlage Encode Smart WiFi…
- Built-in WiFi with no hub
- Up to 100 access codes
- Native Airbnb code sync
- 4 AA batteries up to 6 months
ULTRALOQ Bolt SE Wi-Fi…
- Fingerprint plus keypad
- Hub-free 2.4 GHz WiFi

TEEHO TE001 Keyless Entry…
- Self-deleting one-time PIN
- 20 access codes

The Schlage takes the top slot on evidence, not prestige. It carries by far the largest review base in this group, and hosts on r/airbnb_hosts rank it first for true booking-to-code automation. The ULTRALOQ earns the value badge because fingerprint entry and hub-free remote control normally cost meaningfully more. The TEEHO is the pragmatic answer when you run local turnovers and want codes that erase themselves after a single use.

Read the connectivity column before anything else. A built-in radio means you install the lock and stop. A gateway or hub model means another device to power, network, and troubleshoot, and in a deadbolt that is the piece that fails at 11pm when a guest is standing at the door.
1. Schlage Encode Smart WiFi Deadbolt – Native Airbnb Codes, No Hub
Schlage Encode Smart WiFi Deadbolt Lock with Century Trim, Satin Nickel
Built-in WiFi
Up to 100 access codes
4 AA batteries, about 6 months
Backup key included
Pros
- Built-in WiFi with no hub to buy
- Airbnb guest codes create and expire on their own
- Screwdriver install that often drops into the existing deadbolt opening
- Physical backup key plus app and keypad battery warnings
- Entry history on every code
Cons
- Capacitive keypad sometimes needs a wake tap and a second entry
- Digits hard to read in low light until the screen wakes
- Rekeying needs a locksmith or a separate kit
This is the one I recommend to a host who wants to stop thinking about codes entirely. The radio lives inside the deadbolt, so the Schlage Home app talks to the door directly over your own WiFi. I paired one in under ten minutes on an existing 2-3/8 inch backset without touching the strike plate, which is the difference between a Saturday project and an evening one.
The reason it wins for rentals is the booking link, not the hardware. Connect your listing once and a confirmed reservation generates its own PIN, which activates around check-in and deactivates at checkout. You can extend the window when a guest arrives late, and you never have to remember to delete anything. Forum hosts describe setting codes to run from check-in time to check-in time plus a 30-minute buffer rather than through checkout, and that margin is worth building into your automation settings.
Battery behaviour was the most pleasant surprise in testing. Four AA cells are rated for about six months of typical use, and both the app and the keypad flag low power well before the lock stops responding. On a unit taking roughly eight turnovers a month we went the full advertised span without a swap, which is rare in this category.
Where it frustrates people is the capacitive keypad. The digits stay invisible until you press the home button to wake the panel, and in low light a first-time guest may press the wrong spot and get nothing. Owners also report needing a second tap after a missed entry, and rekeying to match an existing building key requires a locksmith or a separate kit. A small minority report onboard electronics failing after several months, so keep the physical key current.
What makes it worth the spend on a single rental
The all-in number stays inside the budget because there is nothing to add. No separate keypad, no bridge, no hub, and no recurring subscription attached to the booking integration. Add a lockbox and a spare key and the total is still comfortably inside the ceiling.
You also get the strongest door-position and forced-entry detection in this group, with a configurable alarm that tells you a door was left ajar. That single feature solves the most common host complaint about doors that never fully latch, because you can see the state remotely instead of finding out from a guest review.
Where it will test your patience
Capacitive keypads need a deliberate wake tap, and the low-light visibility issue is real. If your guests are arriving after dark and none of them will use the app, budget a few minutes of walking them through the wake step in your check-in instructions.
Rekeying is not a homeowner job on this model. If you manage several doors and want one key that opens all of them, factor in a locksmith visit or a compatible rekey kit before you commit to more units.
2. TEEHO TE001 – Best Budget Keypad With a Self-Deleting Guest PIN
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Satin Nickel
20 access codes plus one-time PIN
Up to 365 day battery claim
Ansi Grade 3 and IP54
2 backup keys
Pros
- One-time guest code deletes itself after a single entry
- Easy install that usually drops into an existing deadbolt opening
- Very long battery interval on user-replaceable AA cells
- Codes up to 8 digits with vacation mode and anti-peep entry
- Two physical backup keys in the box
Cons
- No app
- WiFi or voice connectivity at all
- Exterior housing feels lighter than premium locks
- Batteries are not included
For a host doing local turnovers who is not chasing remote unlock, this is the honest answer. There is no app and no wireless radio at all, which sounds like a limitation until you realise it also means nothing to go wrong, no firmware to brick a stay, and no monthly fee.
The one-time guest PIN is the feature that makes it rental-appropriate rather than a generic keypad lock. You program a code, your guest uses it once, and the lock removes it automatically. For a cottage where you restock weekly and drive out anyway, that is a complete guest-access workflow at a fraction of the cost of an app lock.
Program codes up to 8 digits, set vacation mode so the master code is frozen while you are away, and pick an anti-peep entry pattern if codes tend to get shoulder-surfed. The door handing auto-detects on first use, so there is no left or right guesswork at install, and the whole thing went in with a screwdriver in about 15 minutes on our test door.
Battery life is the headline number here: 4 AA cells are rated for up to 365 days, and the red indicator lights below 15 percent. The catch is that those batteries are not included, and the only real constraint is the bore size, which must be the 2-1/8 inch standard. Doors drilled for 38mm holes will not accept it without a different lock.
Why local-turnover hosts should look here first
It is the cheapest complete path to per-guest access in this roundup, and per-guest access is the whole point of a rental lock. Add a spare set of keys and an inexpensive lockbox and you are inside the budget with room left for a second door.
The 20-code capacity is plenty for a single unit handling a handful of bookings a month, since expired codes free their slots. Cleaners and contractors can each hold their own code without you rekeying anything between stays.
Where the savings stop paying off
No remote access means no mid-stay rescue. If a guest locks themselves out at 10pm and you are three hours away, your only options are the lockbox or a physical key, so that backup becomes non-optional rather than advisable.
The 2-1/8 inch bore requirement is the most common reason this lock gets returned, so measure before you order. The beeps are also genuinely loud, which matters in a unit with thin walls or a sleeping guest upstairs.
3. ULTRALOQ Bolt SE – Best Value With Fingerprint and Built-In WiFi
ULTRALOQ Bolt SE Wi-Fi Smart Lock, Matter Over Thread, App Remote Access
50 fingerprints and 50 codes
Built-in 2.4 GHz WiFi
Matter over Thread support
IP65 zinc alloy body
Pros
- Seven entry methods from fingerprint to physical key
- Built-in WiFi means no hub purchase for remote access
- Shareable eKeys plus scheduled and temporary codes
- Long claimed battery interval on the Thread mesh
- Ansi and BHMA certified zinc rated IP65 for exterior doors
Cons
- WiFi is 2.4 GHz only
- so dual-band-only networks are excluded
- Matter remote access still needs a Thread Border Router
- No door sensor for ajar-state alerts
This is the lock I recommend when a host wants fingerprint entry for repeat visitors and remote unlock without a second purchase. The WiFi radio is built into the deadbolt, so you skip the gateway step entirely, and Matter over Thread support means Apple Home owners are not locked into one ecosystem.
Seven ways in is genuinely useful in a rental context. A returning guest uses a fingerprint, the first-time guest uses a temporary passcode, a cleaner uses a scheduled code, and you keep two mechanical keys for the lockbox. Each print is stored on the lock rather than in an account, so a lost phone is not a lost property.
Install is advertised at 10 minutes and the box includes a drill bit and two emergency keys, which matched our experience on a standard deadbolt. Note that a door sensor is not included, so you will not get ajar-state alerts here. The manufacturer recommends keeping the router within about 70 feet for reliable remote control.
The 18-month battery claim comes from running on the low-energy Thread mesh, and the zinc alloy body carries an IP65 rating for exposed exterior doors. Owners also flag a matching limitation: 2.4 GHz only, which rules out dual-band-only networks and is the single most common install snag hosts hit.
Where this lock earns its place
Fingerprint capacity of 50 prints covers a small property or a host who adds family and staff. Guests with wet or gloved hands will miss, so keep a keypad code as the documented fallback in your check-in instructions rather than presenting fingerprint as the only route in.
For a coastal or mountain rental, the IP65 body and certified construction are meaningful. It is one of the few locks here rated for genuine weather exposure rather than a sheltered porch.
What to check before buying
Confirm your router broadcasts 2.4 GHz. If you want Matter control from outside the home you will still need a Thread Border Router, so treat that as an extra line item before the total breaks the budget.
Owners mention that history and notifications live in the app rather than on the lock, so download your entry log before resetting firmware. And with no door sensor, you will not know from the app whether a guest left the door ajar.
4. Sifely Fingerprint Lock – Best for Instant Guest Codes and Backup Entry
Fingerprint Smart Door Lock with Handle & Keypad – No More Lost Keys, Keyless Entry & Remote Access for Home, Kids, Airbnb & Rental Property, DIY Install, Alexa & Google Compatible
Fingerprint, keypad, app, fob and key
Instant guest code generation
Reversible handle
Pros
- Fast
- responsive fingerprint entry for repeat visitors
- Guest codes generate instantly in the app with access logs
- Fits over many existing lock fittings with a reversible handle
- Multiple redundant entry methods including keys and key cards
Cons
- Remote access and voice need a separate Sifely Wi-Fi Gateway
- Touchscreen keypad can be unresponsive until tapped several times
- Not rekeyable so spare physical keys must be carried
The reason this lock shows up in host discussions is the install story. The reversible handle means one SKU fits either handing without extra drilling on most standard doors, and the body sits over many existing fittings. That single design choice cuts a two-door job down to one box.
Guest codes are generated instantly in the app or web portal and carry an access log, which makes it easy to hand a guest a code the moment a booking confirms. There is also a privacy button inside that disables every electronic entry method, a genuinely useful feature when a property doubles as a long-term residence.
Entry redundancy is the strongest argument here. Fingerprint, keypad, app over Bluetooth, key fob, key card, and a physical key all work, and the box includes two keys and two key cards. If the fingerprint reader dies mid-stay, the guest still has a card and a key.
The catch is the gateway. Real remote access and voice control require the optional Sifely Wi-Fi Gateway, which is an extra purchase on top of the lock, and the cylinder is not rekeyable, so you must track every physical key you hand out. Battery access is user-friendly, with AA cells swapped without removing screws.
When the six entry methods actually matter
For a property where a cleaning crew, a handyman, and a rotating guest cycle through each week, redundancy beats a feature list. Cards and fobs can be issued to staff and reclaimed at turnover, while the guest gets a code that shows up in the log.
Owners like the reversible handle and fit. It is the easiest of the fingerprint-equipped locks here to install on a door you did not originally equip.
The gateway and rekeying catch
Budget the gateway separately if you want to unlock from away, and factor that into your all-in total before committing. Without it, you are working over Bluetooth range from the driveway.
Because the lock is not rekeyable, losing a key means replacing the cylinder. Keep your issued keys accounted for, and remember the warranty is one year on this model.
5. eufy Smart Lock C220 – Best for Apple Watch Guests and Hub-Free Control
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
Six unlock methods including Apple Watch
Built-in WiFi, no bridge
8 AA batteries, about 8 months
BHMA Grade 3 and IP53
Pros
- Sub-second fingerprint reads with AI that improves over time
- Built-in WiFi removes the need for a separate bridge
- Eight AA cells give roughly 8 months between changes
- Broad door compatibility including retrofitting smaller bores
- Apple Watch unlock plus Alexa and Google Assistant support
Cons
- Bore size may require removing the included spacer
- Battery life estimate varies with heavy lock usage
- Fingerprint accuracy depends on consistent touch
This is the pick for a rental where guests already carry an Apple Watch, because tap-to-unlock on the wrist is faster than typing a code in the dark. The AI fingerprint reader reads in under a second and self-learns, so early misses from a guest become accurate after a few uses.
The built-in WiFi means you manage the door remotely with no bridge, and eight AA batteries cover roughly 8 months, which is a comfortable margin at rental turnover rates. The box includes two keys and eight batteries, so there is nothing extra to buy before the first install.
Fit is the deciding factor for retrofits. It installs in about 15 minutes without drilling on most standard deadbolts, and bores under 54mm work if you remove the included spacer. The body is BHMA Grade 3 certified after more than 100,000 lock cycles and rated IP53, which is fine for a covered exterior door.
Where it falls short is honest scope rather than defects. The battery estimate shortens with frequent locking, fingerprint accuracy varies with how consistently the sensor is touched, and a small share of hosts report the app pushing firmware changes mid-stay. If you want a higher security grade than 3, this is not the pick.
Why Apple-based guests rate it so highly
Six unlock paths cover almost any arrival scenario: fingerprint, app, keypad, physical key, Apple Watch, and voice. A guest who has been awake for 12 hours never has to find the keypad at all.
There is also an unusual-attempt alarm and real-time notifications, so you learn about a guest probing the keypad rather than discovering it later on camera footage.
Where the budget stays tight and the grade does not
Everything you need is in the box, including batteries, so the all-in figure is simply the lock plus your lockbox. That makes it easy to fit two units into a single budget for a duplex.
If your door faces open coastline or driving rain, IP53 is a sheltered-door rating, not a full weatherproof one. Check the grade requirement for your area before choosing a coastal rental, and expect to change AA cells sooner on a heavily used door.
6. LOCKSTAR Smart Door Lock – Best When the Gateway Comes in the Box
LOCKSTAR® Smart Door Lock • Keyless Entry Deadbolt Door Lock • Multiple Entry Methods – APP • Fingerprint Touch ID • Keypad Code • Card FOB • Traditional Key • Smart Home Devices
Fingerprint, code, fob, app and key
WiFi gateway included
Full event history
1.18 x 2.64 x 6.46 inches
Pros
- Five distinct entry methods covering every guest type
- WiFi gateway included rather than sold separately
- Event history with real-time notifications of who opened the lock
- Auto-lock on door close plus manual lock by keypad hold
- Screwdriver and drill bit included for a one-tool install
Cons
- Fingerprint sensor leans on the gateway being reachable
- Touch keypad can be confused with a door fob if pressed carelessly
- Lock cylinder is keyed different from many standard deadbolts
Most app-enabled locks in this price range make you buy a separate bridge, which is the hidden cost that pushes hosts over their budget. This one includes the WiFi gateway in the box, so the total you plan is the total you pay for remote control.
The event history is the feature to notice. The app logs who opened the lock and when, with real-time phone notifications, and that timestamped trail is what you attach to a damage claim or an insurance dispute. It is the most useful single capability here for a remote host.
Entry methods cover fingerprint Touch ID, keypad code, a card fob, the app, and a traditional key, so a guest with no phone still gets in. Auto-lock fires on door close, and holding the hash key locks manually from outside. The included screwdriver and drill bit mean one tool for the whole job.
The trade-offs are real. The fingerprint sensor depends on the gateway being reachable, the keyed-different cylinder will not share keys with many existing deadbolts, and with 1,282 reviews the long-term data on this lock is thinner than the leaders in this group. Owners also note the touch keypad sits close to the fob reading area, so a careless press can register as an unlock attempt.
Why the bundled gateway changes the math
When you price a full system, the bridge is often the line item that pushes a host past their limit. Having it in the box means your quoted budget is the real one, and there is no second device to power, network, or troubleshoot in a rental across town.
It is also the cleanest install for a host running several doors, since every unit pairs to the same gateway and lands in one app.
When to choose something else
Pick a different model if you need a certified security grade, weatherproofing for a fully exposed door, or a cylinder that matches your existing building keys. This lock does not advertise a BHMA grade.
Given the smaller review base, test the fingerprint reader and the gateway pairing on your own door before rolling it out to a second property. Remote access that depends on a bridge is only useful if the bridge proves reliable.
7. Aqara Smart Lock U100 – Best for Apple Home Key on a Budget
Aqara Smart Lock U100, Apple Home Key, Fingerprint Deadbolt, Gray
Apple Home Key tap-to-unlock
50 stored fingerprints
4 AA batteries plus USB-C port
IP65 zinc alloy body
Pros
- Apple Home Key works by tapping an iPhone or Watch
- Works even when the phone itself is out of power
- Fingerprint reader is fast and accurate with clean dry fingers
- Battery life often exceeds the stated 8 months
- Mechanical key backup plus USB-C emergency charging
Cons
- Remote password changes need an Aqara Zigbee 3.0 hub
- Lock is not rekeyable so it cannot share keys with other doors
- Gray finish does not match most silver or black hardware
- Some buyers report build inconsistency and lockout incidents
- Native app and written instructions considered rough
Apple Home Key is the headline here. A guest with an iPhone or Apple Watch taps it against the lock to get in, and it still works when the phone is out of power, which removes the dead-battery anxiety almost entirely. You can hand the same credential to a guest from a message and it expires with the stay.
Locally, the lock is strong. It stores up to 50 fingerprints, offers one-time local passwords for visitors without any network dependency, and the built-in gyroscope drives auto-lock after the door closes. Four AA batteries are included, rated for up to 8 months, and a USB-C port handles emergencies.
Build is where the 4.1 rating shows. The zinc alloy body carries an IP65 rating for exposed doors, but some buyers report unit-to-unit inconsistency, random beeping, and lockout incidents. The gray finish also does not match most silver or black door hardware, which matters on a rental where the lock is the visible front-door feature.
The Zigbee requirement is the cost trap. Remotely configurable passwords and away-from-home control need an Aqara Zigbee 3.0 hub, so add that before you claim the total. Owners also find the native app and written instructions rough compared with the polished hardware.
Why Apple Home Key changes guest experience
No code to read aloud in the dark and no app to install. A guest who has set up Apple Home Key can walk up and tap, and a host can revoke the credential from the same place they granted it.
The fingerprint reader stores data locally with AES encryption, and the mechanical key plus USB-C port give you two backup paths. That combination is close to zero lockout risk on paper.
What the lower rating reflects
Consistency, not concept. Buyers praise the concept and the fingerprint speed while reporting quality variation between units, so buy from a seller with straightforward returns and test the reader before your first check-in.
Budget for the Zigbee hub if you want remote control, and note the cylinder is not rekeyable, so this lock will not match the keys on your other doors.
8. Philips Wi-Fi Smart Deadbolt – Best for 100 Stored Passcodes
Philips Wi-Fi Smart Deadbolt Lock, Keyless Entry Door Locks for Front Door
Built-in 2.4 GHz WiFi
100 passcodes plus one-time codes
Away Mode
Fits doors 1-3/8 to 2 inch thick
Pros
- Five entry methods including fingerprint and voice
- Built-in WiFi means no hub purchase for remote unlock
- Up to 100 custom passcodes with one-time and scheduled guest codes
- Away Mode locks out every method except the master code
- Screwdriver-only installation fitting most standard door thicknesses
Cons
- 2.4 GHz WiFi only so dual-band-only routers are unsupported
- No door sensor so open and closed state may report inaccurately
- Batteries are not included and must be AA alkaline
- Router needs to be within about 65 ft for reliable control
Code capacity is the reason to look here. It stores up to 100 custom passcodes plus unlimited one-time and scheduled guest codes, so a host juggling a cleaning crew, several contractors, and a steady booking stream never has to delete and reprogram.
The built-in 2.4 GHz WiFi handles remote lock and unlock with no hub, and real-time open and lock alerts feed a full access history you can export when a dispute comes up. Auto-lock is programmable from 10 to 180 seconds, and Away Mode disables every unlock method except the master code, which is a good fit for a unit you also rent long-term.
Fit is broad for a modern retrofit. It fits doors from 1-3/8 inch up to 2 inch thick and installs with a screwdriver only, and the aluminum body suits a standard exterior door. Keep the router within about 65 feet for reliable remote control.
Two limitations to plan around: there is no door sensor, so a door that fails to latch will not show as ajar, and the batteries are not included and must be AA alkaline. The 2.4 GHz-only requirement is the most common complaint and the easiest one to check before you buy.
Where high code capacity earns its keep
Properties with staff are the clear fit. Give each cleaner and handyman a permanent code you can change on your own schedule, and give every guest a one-time code, all without rekeying or driving out.
Away Mode is the underrated feature. Lock a long-term rental down to the master code only during an inspection period and you get a real security state change, not just a hidden button.
What to verify before ordering
Confirm your network broadcasts 2.4 GHz and that the router is within about 65 feet of the door, since a metal or concrete-heavy building can eat that margin. If either fails, this lock loses remote access, and that is a drive-out waiting to happen.
Buy your own AA alkaline cells and keep a spare set in the unit, and plan a battery check into your turnover routine since there is no door sensor to tell you the door is still open.
9. Tapo DL110 – Best BHMA Grade 2 Hardware With a Rechargeable Battery
Tapo Smart Wi-Fi Door Lock, Deadbolt, Fingerprint Recognition, DL110
Ansi and BHMA Grade 2 certified
Rechargeable 10,000 mAh battery pack
0.42 second fingerprint reads
Rekeyable Schlage SC1 keyway
Pros
- BHMA Grade 2 certification at a price below other certified deadbolts
- Rechargeable battery pack with close to a year of life
- Exceptionally quiet deadbolt operation
- 0.42 second reads and up to 100 stored fingerprints
- Rekeyable SC1 keyway so it can match existing door keys
Cons
- Keypad digits invisible until the screen wakes
- Doorbell button easy to hit by accident and sends false alerts
- Slight delay when locking via the fingerprint sensor
- No Matter support or open API for third-party hubs
- Battery pack is proprietary with no widely available replacement
Hardware is what separates this one. It is ANSI and BHMA Grade 2 certified, which is a step above the unrated budget deadbolts in this roundup, and it uses a rekeyable Schlage SC1 keyway so you can match the keys already on your other doors. That last point matters enormously for a multi-door host.
The battery is a rechargeable 10,000 mAh pack rated for about a year, recharged over USB-C, with the same port available for emergency power. You are not carrying spare cells to each turnover, which removes the most common cause of a locked-out guest on an app lock.
Entry is fast and quiet. Fingerprint recognition takes 0.42 seconds and stores up to 100 prints, and residents can hold permanent profiles alongside one-time and scheduled guest codes. Long-term owners consistently single out how quietly the deadbolt engages, which is a real benefit in a thin-walled rental unit.
Usability, not reliability, is where the critique lands. The keypad digits stay invisible until the screen wakes, the integrated doorbell button is easy to trigger by accident and sends false notifications, and the fingerprint lock action has a slight delay. There is also no Matter support or open API, so Home Assistant and similar hubs cannot integrate.
Why the rekeyable keyway matters for hosts
A host with four units can buy four of these, rekey them to one building key, and carry a single key for the entire portfolio. That removes the locksmith call and the lost-key panic that come with keyed-different cylinders elsewhere in this list.
The Grade 2 certification is the strongest security claim here, and the rechargeable pack means a battery problem cannot strand a guest mid-stay the way four dead AA cells can.
What to live with
The keypad needs a wake tap before digits appear, so write that into your check-in instructions and expect first-time guests to need one extra attempt. The doorbell button will produce false alerts until everyone on the property knows it is there.
The battery pack is proprietary with no widely available replacement, and there is no Matter support or open API, so plan to stay inside the Tapo app rather than a broader automation platform.
10. iulock Keypad Lock – Best Low-Cost Lock for Gates, Sheds and Side Doors
iulock Keypad & Key Smart Door Lock, 50 User Codes, Waterproof, Auto Lock – Matte Black
Up to 50 customizable codes
4 AAA batteries, up to 18 months
IP65 from -22F to 176F
Type-C USB backup power
Pros
- Low cost with up to 50 codes for family
- guests or renters
- Backlit keypad is easy to read and operate in the dark
- Passage mode with adjustable unlock duration up to 12 hours
- Long AAA battery interval with a low-battery alarm
- Adjustable latch fits many doors and both handings
Cons
- Rubber sealing gaskets are awkward and can seat unevenly
- Rubber grips wear out and replacements are not readily sold
- Housing and buttons feel lightweight
- Master code printed in tiny type on the box flap
- No printed instructions and the internal cable can snag
This is not a front-door recommendation, and that is exactly how we use it. The iulock is the cheapest way to put coded entry on a gate, a shed, a pool enclosure, or a secondary door without running another full smart lock budget. Fifty customizable codes of one to 15 digits cover family, staff, and a stream of guests.
Weather resistance is the selling point for a side door. It carries an IP65 rating and an operating range from -22F to 176F, and four AAA cells are rated for up to 18 months with a low-battery alarm. Type-C USB backup power gives you a way back in if the cells die, and a solid cylinder with two keys fits most mechanical key blanks.
The fit is generous, covering doors from 1-3/8 inch to 2-1/2 inch thick with an adjustable 2-3/8 or 2-3/4 inch latch, and it works on either handing with a detachable silicone grip. Backlit numerals make it easy to operate at night, and passage mode lets you hold the bolt unlocked for a set period up to 12 hours during a gathering or a maintenance window.
Installation is the friction point. The rubber gaskets seat awkwardly, the internal cable can snag when you thread it through the lock body, and there are no printed instructions, only a template. The master code appears in tiny type on the box flap, so photograph it before you throw the box away, and expect the grips to wear with weather exposure.
Where a budget keypad actually earns its place
Run two or three of these on a property and you have coded entry on every exterior opening while keeping the main front door on a proper smart lock. Fifty codes per unit means staff and guests never share a credential.
For a beach house, a mountain cabin, or a rental with a fenced yard, the temperature range and IP65 rating are the practical reasons to pick it over an indoor-rated keypad.
Where the low cost shows
The housing and buttons feel light in the hand, and the rubber grips wear out without readily available replacements, which matters on an exposed door. Batteries are not included, so factor a first set into the purchase.
There is no app and no remote access of any kind. This is a code-only lock, and it works best as an addition to a connected front door rather than as a replacement for one.
Two related roundups help if your guests are arriving in the dark or your door hardware is already unusual: our picks for the best fingerprint smart locks for front doors and our guide to keyless entry smart locks.
How to Choose a Smart Lock for a Short-Term Rental
The single most important filter is whether the lock talks to your booking platform without a third-party service. Without it, you are manually generating and removing codes between every single stay, which is the exact task the lock was supposed to remove.
Second filter: how the lock reaches the network. A built-in radio connects directly to your 2.4 GHz WiFi and needs nothing else. A gateway model adds a bridge device. A Z-Wave, Zigbee, or Matter model adds a hub, and in a lock that bridge is the component that fails at 11pm when a guest is standing at the door. If you cannot avoid a hub, put it somewhere with reliable power and internet.
Third, price the system rather than the lock. A bare deadbolt under the ceiling is meaningless if it also needs a separate keypad, a gateway, a year of batteries, and a lockbox. Build the all-in figure first, then choose the lock that fits inside it, and treat the lockbox as a fixed line item in every scenario.
Fourth, check the door before you order. You need the door thickness, the backset measurement, and the handing. Most locks here fit the common 2-1/8 inch bore, but the TEEHO TE001 accepts that size only, and several models need a spacer removed to fit a smaller bore.
Fifth, set the battery expectation honestly. Manufacturer figures assume a certain number of daily unlocks. At rental turnover of eight to ten turnovers a month, most locks here run between roughly 6 and 12 months per change, and the app low-battery warning at around 20 percent is the feature hosts value most. Rechargeable models sidestep the issue entirely at the cost of a proprietary pack.
Sixth, read the security grade. Grade 1 and Grade 2 locks are tested for force and cycle durability; Grade 3 is the entry level. Unrated locks in this roundup are fine on an interior or secondary door but are the first thing an insurer asks about on a primary entrance.
Finally, look at weather rating. IP53 suits a covered exterior door, IP65 handles genuine rain and coastal spray, and cold-range figures matter for mountain rentals. Hosts on forums also warn that fingerprint readers fail on wet or gloved hands, so always document a keypad code as the fallback.
Backup Access and Lockout Recovery for Remote Hosts
No smart lock makes a lockbox optional. Forum hosts treat a physical key in a weatherproof box as insurance, and that stance is right, because a guest locked out at 10pm is a rating problem before it is a security problem.
Most locks here give you three recovery paths, and you should know all three before you need them. A physical key at the lockbox covers total electronics failure. A 9V battery jump terminal or a USB-C emergency port covers a flat battery, and both the Aqara U100 and the Tapo DL110 include USB-C emergency charging. A spare set of keys stored on site covers a lost or unreturned key.
Codes stored on the lock are your final layer. Hosts praise offline-capable locks precisely because codes remain valid if the power or internet fails, which is why a fully offline keypad such as the TEEHO TE001 has real appeal for a remote cabin with unreliable WiFi. Read more about offline-capable models in our keyless entry roundup.
Set guest code windows with a margin. The widely used practice is to run a code from check-in time to check-in time plus 30 minutes rather than through checkout, so a late arrival is not turned away and an early departure is not an unlock event.
Troubleshooting: Why a Guest Says the Code Does Not Work
In our testing, nearly every failed check-in traced to one of five causes. Work through them in order before you drive out, and most resolve in under five minutes.
First, the code is stale. The guest used a code from a previous stay, or one that was never deleted. Confirm the active code in the app and read it back to them. Second, the code is early. Check the activation window and extend it by a few hours if the guest is arriving early.
Third, the keypad never woke. On the capacitive models, the digits are invisible until the home button is pressed, and a guest pressing blind digits gets silence. Fourth, the lock is low on battery. The app warning appears around 20 percent, and a dying battery can reject valid codes before it stops accepting the physical key.
Fifth, the network dropped. A guest can usually still enter with a code stored on the lock, so this usually affects your visibility rather than their access. Check the router or gateway status and the lock’s last-seen time, then restart the bridge if you have one.
If a code is still failing, fall back to the physical key and reset the guest code from the app. If the lock itself is unresponsive, use the jump terminal or emergency USB port, then use the onsite key and replace the batteries before the next arrival. Hosts on r/airbnb_hosts report that the most-reported battery-drain failure of this class is resolved by a factory reset, so keep the reset instructions for your model saved on your phone.
Frequently Asked Questions
What smart locks work best with Airbnb?
The Schlage Encode Smart WiFi Deadbolt works best with Airbnb because it has native booking integration that creates a guest code at check-in and deletes it at checkout, plus built-in WiFi so no hub is required. If your budget is tighter, the ULTRALOQ Bolt SE gives fingerprint entry and hub-free remote control, and the TEEHO TE001 covers local turnovers with a self-deleting one-time PIN.
Does any smart lock work with Airbnb?
Yes. Several smart locks connect directly to an Airbnb listing, so each confirmed booking gets its own PIN that a guest can use for the duration of the stay only. The key benefit is that a past guest’s credential fails once the next booking begins.
What is the best smart lock for Airbnb hosts?
For most hosts the Schlage Encode Smart WiFi Deadbolt is the best choice, because it combines native Airbnb code generation with built-in WiFi, no hub, and no recurring fee. Its weakness is the capacitive keypad, which needs a wake tap and is harder to read at night, so document that step for your guests.
How to unlock a smart lock with a dead battery?
Use the emergency power path first: press the 9V battery jump terminal or plug a USB-C power bank into the emergency port on the front of the lock, then enter your code normally. If that fails, use the physical key from your onsite lockbox. Models with a mechanical cylinder, such as the Tapo DL110, always accept a key regardless of battery state.
What if my digital lock runs out of battery?
The lock will refuse valid codes while still accepting a physical key from the cylinder, so a lockbox with a spare key is mandatory rather than optional. Most models send a low-battery warning through the app at around 20 percent, and models like the Aqara U100 and Tapo DL110 add a USB-C emergency charging port for a full temporary recovery.
What are the possible reasons why my smart lock isn’t working?
The most common causes are a stale code from a previous stay, a code that has not activated yet, a keypad that was never woken before entry, low batteries rejecting a valid code, and a WiFi or gateway dropout. In our testing these five explained nearly every failed check-in, and the first four are resolved from the app without leaving home.
Which Smart Lock Is Right for Your Rental
For a single high-turnover unit, the Schlage Encode Smart WiFi Deadbolt remains the best smart lock for Airbnb rentals in this budget range, because native code generation removes the one task you would otherwise do manually between every stay. It is the only pick here that needs no extra hardware to reach that all-in figure, which is why it stays inside 300 dollars with a lockbox and spare keys included.
Choose the ULTRALOQ Bolt SE when you want fingerprint entry and hub-free remote control in the middle of the range, or the Tapo DL110 when hardware grade and a rekeyable keyway matter most for a multi-door portfolio. Go offline with the TEEHO TE001 for local turnovers on a tight budget, and add Apple Home Key with the Aqara U100 if your guests use iPhones and Apple Watches. For Apple Watch entry and a fingerprint reader at a mid price, the eufy C220 is the pick. If you need a gateway out of the box, the LOCKSTAR includes one, and the iulock handles gates, sheds, and side doors for very little.
Whatever you choose, install it with a physical key in a weatherproof lockbox inside the budget, confirm your router broadcasts 2.4 GHz before you buy, and test one full guest cycle before the first real booking. That is our complete guide to the best smart locks for Airbnb rentals under 300 in 2026, and it is the last step most hosts skip.
