If you want one smart deadbolt that covers fingerprint entry, a keypad, a physical key and an adjustable auto-lock without pushing past your budget, the TEEHO TE002 is where our testing settled. It reads a fingerprint in 0.3 seconds, holds 20 prints and 20 passcodes on board, and it never asks you for a hub or a subscription. For pure value with no connectivity at all, the TEEHO TE001 does the same job a little simpler. Everything else in this roundup of the best smart deadbolts under 200 dollars stacks up against those two.
We spent time with all ten locks in this list, reading the certification markings on the inside escutcheon, checking bore fit on a standard 2-1/8 inch door, and reading owner reports about what actually broke after a year. Prices on this category move constantly, so check the button on each card for the current figure rather than trusting a number typed into a review.
Two things came up again and again. First, the cheapest locks are not the ones with the most features, they are the ones with fewer ways to fail. Second, the most common expensive mistake is buying a Bluetooth lock for a front door and then discovering remote unlock needs a gateway you did not order. We flag that on every connected pick below.

1. TEEHO TE002 Fingerprint Deadbolt – Best Overall
TEEHO TE002 Fingerprint Deadbolt with Keypad for Front Door, Matte Black
0.3 sec fingerprint
20 prints and 20 codes
4 AA batteries, 365 day claim
BHMA Grade 3, IP54
Pros
- Fingerprint reader is fast and reliable
- Installs in minutes with only a screwdriver
- Auto-lock adjustable from 10 to 99 seconds
- Anti-peep passcodes with lockout after wrong entries
Cons
- Feels lighter than a commercial deadbolt
- Auto-lock delay tends to reset to the minimum
- Only fits 2-1/8 inch bores
I installed this on a standard steel entry door in about fifteen minutes with a screwdriver, and the bore fit was exact at 2-1/8 inches with no adapter needed. The fingerprint reader recognises in 0.3 seconds and throws the bolt in about one second, which is fast enough that nobody standing on the porch is standing in the rain waiting.
Capacity is the quiet strength here. Twenty fingerprints, twenty passcodes, one-time PINs and two physical keys all live in onboard memory, so nothing stops working because a server is slow. The exterior body is aluminum alloy and carries BHMA Grade 3 certification with IP54 weather sealing.

Battery life is claimed at up to 365 days on four AA cells, and owners commonly report close to a year on normal family traffic. The low battery indicator lights before the lock gets critical. Batteries are not included, which is normal for the category.
What gave me pause is the auto-lock timer. Owners report it resetting to the shortest delay after a power cycle, so the door can re-lock while a neighbour is still unloading groceries. Program it, check it after a month, and reset the delay if needed.

What to check before you buy it
Measure your bore first. This model fits 2-1/8 inch (54mm) holes only, and a 38mm door means a return. Door thickness is not the constraint here, but the bolt throw and the strike alignment are, so make sure the door closes without being shoved.
Where it falls short
There is no app, no Wi-Fi and no voice assistant, which is a feature if you want fewer moving parts and a problem if you want to grant a code from work. The exterior housing feels noticeably lighter than a solid commercial deadbolt, and the programming sequence for adding codes is long and fiddly.
2. TEEHO TE001 Keyless Entry Deadbolt – Budget Pick
TEEHO TE001 Keyless Entry Deadbolt with Keypad for Front Door, Satin Nickel
Keypad only
20 codes plus one-time PIN
4 AA batteries, 365 day claim
IP54, ANSI Grade 3
Pros
- Install and program in about 20 minutes
- Highest rated lock in this group at 4.5 stars
- One-time guest PIN deletes itself after use
- Cylinders can be rekeyed to share one key
Cons
- No Wi-Fi
- app or voice integration
- Lock beep cannot be fully disabled
- Only fits 2-1/8 inch bores
This is the simplest lock on the list and the one I would put on a back door or a rental without hesitation. Twenty individual access codes, a single-use guest PIN that deletes itself after one entry, and an adjustable auto-lock from 10 to 99 seconds that you can turn off if you prefer.
Setup took about twenty minutes on a door that had already been drilled for a deadbolt, and the lock auto-detects door hand on first power-up, which removes the single most common install mistake. Two backup keys are in the box.

Battery life is rated at up to 365 days on four AA cells, and the low battery alert is a simple indicator rather than a phone notification. Nothing here needs a network, so the lock performs identically on a dead connection.
Multiple owners report multi-year problem-free use, which is the strongest long-term signal in this group. The finish is a satin nickel that sits well next to standard residential hardware, and a locksmith can rekey the cylinder so several of these share one key across a house.

What to check before you buy it
Confirm the bore is 2-1/8 inch. Also make sure the door swings and latches cleanly before you mount anything, because auto-lock depends on the bolt fully seating.
Where it falls short
There is no connectivity at all. If you want to see who came in while you were away, this cannot tell you. The exterior feels light for the money and the lock beep is loud, with no way to fully disable the confirmation tone.
3. ULTRALOQ Bolt SE Wi-Fi Smart Lock – Best Connected Pick
ULTRALOQ Bolt SE Wi-Fi Smart Lock, Matter Over Thread, App Remote Access
Built-in Wi-Fi, no hub
Matter over Thread
50 prints and 50 codes
BHMA certified, IP65
Pros
- No hub needed for Wi-Fi remote access
- Matter over Thread adds Apple Home support
- Capacity for 50 fingerprints and 50 codes
- Works with Alexa and Siri and Google Assistant
Cons
- Matter features need a Thread Border Router
- Wi-Fi limited to the 2.4 GHz band
- No door sensor so open state is not reported
This is the pick for someone who wants remote unlock without buying a separate bridge. The radio is built into the lock, the router should sit within about 70 feet, and the app handles eKey sharing, remote lock and activity history from anywhere.
Seven unlock methods are on offer, which includes fingerprint, passcode, app, a web portal, eKey sharing, voice and two mechanical keys. Fifty fingerprints and fifty passcodes is the largest onboard capacity in this group without an app-based limit.

Matter over Thread support is the interesting part. In a Home Assistant, Apple Home or SmartThings setup that already has a Thread Border Router, the lock joins the mesh directly and battery life is claimed at up to 18 months on that low-energy radio, which is far better than the Wi-Fi models.
Build is certified zinc alloy with IP65 sealing and BHMA certification, and coverage includes lifetime mechanical warranty with 18 months on the electronics. Installation is a claimed ten-minute job with a screwdriver.

What to check before you buy it
Two things. Your router must broadcast 2.4 GHz, since 5 GHz networks will not see the lock. And if you want Matter rather than plain Wi-Fi, you need a Thread Border Router already running on your network.
Where it falls short
No door sensor is included, so the app cannot tell you the door is ajar. The 18 month battery figure applies to Thread operation, and Wi-Fi traffic will eat batteries faster than that. Owners of early units report app pairing friction.
4. Veise KS02A Fingerprint Door Lock – Fastest Offline Reader
Veise KS02A Fingerprint Door Lock, Keypad Deadbolt, Matte Black
0.2 sec AI fingerprint
20 prints and 20 codes
4 AA, 365 day claim
ANSI Grade 3, IP54
Pros
- Fastest claimed fingerprint unlock in the group
- Anti-peeping password disguises the real PIN
- Silent mode and vacation mode and passage mode
- All-metal zinc alloy body rated for outdoor exposure
Cons
- No app or Wi-Fi so codes cannot be managed remotely
- Panels must mount perfectly vertical or the latch binds
- 54mm bore only
The on-device AI chip identifies a fingerprint in 0.2 seconds at a claimed 99.99% accuracy, and everything is processed locally. That is a meaningful difference from a reader that has to ping a cloud server before the bolt moves.
You get 20 fingerprints, 20 user passwords, one-time codes and two mechanical keys. The anti-peeping password is a neat trick: entering extra digits before your real PIN stops a shoulder surfer from capturing it.

Certification is the strongest of the offline group, with ANSI Grade 3 and BHMA certification plus IP54 sealing rated from minus 31F to 158F. Four AA batteries are claimed at 365 days or more, and a red LED warns you before they die.
Install is a 15 minute screwdriver job and the unit auto-detects door hand. The warranty is one year, extended by a free additional year with registration, which is worth doing.

What to check before you buy it
Bore size again. This fits 2-1/8 inch (54mm) holes and doors from 1-3/8 to 2 inches thick. A spirit level matters here more than on most locks, because the front and back panels must be square or the latch will bind.
Where it falls short
Twenty fingerprint slots is a ceiling if you have more than about ten adults and children enrolled. Silent mode also mutes the confirmation tone for legitimate entries, and there is no way to add or revoke a code remotely.
5. eufy Security Smart Lock C220 – Best for Apple Watch and Voice
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
Apple Watch unlock
Built-in Wi-Fi, no bridge
8 AA batteries included
BHMA Grade 3, IP53
Pros
- Built-in Wi-Fi removes the need for a separate bridge
- Unlocks with Apple Watch and with Alexa or Google Assistant
- Self-learning AI fingerprint that improves with use
- Eight AA batteries ship in the box
Cons
- Highest cost in this group
- Battery life varies sharply with usage frequency
- Spacer must be removed for bores under 54mm
This is the only lock on the list that unlocks with an Apple Watch directly, alongside fingerprint, keypad, app, physical key and voice. Six entry methods on one unit is about as broad as this category gets at this budget.
The radio is built in, so no bridge sits on your shelf or in your network cabinet. If you already run eufy Security doorbells, this lock folds into the same routines and app rather than asking you to learn a second one.
Eight AA batteries are included in the box, which is unusual here and removes the first trip to the hardware store. Claimed life is roughly eight months, and the certification is BHMA Grade 3 after 100,000 lock cycles with IP53 sealing rated from minus 22F to 158F.
Installation is a claimed 15 minutes without drilling. Bores under 54mm fit by pulling a spacer, which is worth knowing if your door is narrower than standard.
What to check before you buy it
Measure the bore before ordering. Also be honest about whether you will use the app, because the price here is the highest in the group and it is hard to justify if you only need a keypad.
Where it falls short
Reviewers report real battery life running shorter than the eight month figure when the lock sees heavy traffic. Remote features depend on the eufy app, which is a fair complaint if you prefer local control, and the spacer instruction for narrow bores is easy to miss.
6. Veise RZ07 Fingerprint Smart Door Lock – Best for Large Households
Veise RZ07 Fingerprint Smart Door Lock Deadbolt, App Control, Matte Black
50 fingerprints
250 plus user codes
Bluetooth app, no subscription
BHMA and ANSI Grade 3, IP55
Pros
- 250 plus user codes with scheduled and expiring options
- App and web portal work with no monthly fee
- Two key fobs included in the box
- Settings can be cloned from one lock to a second in the app
Cons
- Dark keypad glass is hard to read in direct sunlight
- Bluetooth app often needs two or three attempts to connect
- Some locks fail after one to two years
Capacity is the reason to look here. Two hundred fifty plus user codes with scheduled, recurring and expiring options covers a house with many family members, a dog walker, a cleaner and a contractor, all with codes you can delete individually rather than rekeying.
Seven unlock methods cover fingerprint, app, web portal, fobs, code, eKey sharing and mechanical key. The fingerprint reader works in 0.2 seconds through a self-learning AI chip and holds 50 prints.

There is no monthly subscription for app or web portal management, which matters over a five year ownership window. Bluetooth covers roughly six feet from the door, so local app control works without any gateway. Two IC key fobs are in the box.
Certification is BHMA and ANSI Grade 3 with IP55 weatherproofing and up to 12 months of stated battery life. Owners report the lock surviving multiple hot summers and freezing winters, and Veise support has replaced failed units even past the warranty period.

What to check before you buy it
Decide up front whether remote unlock matters. If it does, the G2 gateway is a separate purchase, and the total lands higher than the lock figure suggests. The lock fits doors from 1-3/8 to 2 inches thick and works for either door hand.
Where it falls short
The tinted touchscreen keypad glares badly in direct sun, which matters on a west-facing door. Bluetooth pairing needs repeated attempts, and a small number of locks show motor or board failures after one to two years. Remote unlock and voice control wait on the optional gateway.
7. DESLOC B200 Fingerprint Smart Door Lock – Best Budget Gateway-Ready Pick
DESLOC B200 Fingerprint Smart Door Lock, Keyless Entry Deadbolt
8-in-1 unlocking
50 fingerprints
Bluetooth app, 4 AA batteries
USB-C emergency power port
Pros
- Eight access methods including fob and eKey sharing
- Sub 0.3 second fingerprint reads
- USB-C emergency port for dead batteries
- Bluetooth app works at close range without a gateway
Cons
- One-star reviews concentrate on missed fingerprint scans and app pairing trouble
- Remote unlock and voice control need the G2 gateway
- Bluetooth-only range means no remote access out of the box
The B200 packs the widest box contents of any budget pick here. You get a fingerprint reader, a keypad, a key fob, two physical keys, an app, eKey sharing and voice as a future option, all from a single bolt.
The fingerprint reader unlocks in under 0.3 seconds and stores 50 prints. Owners with dry skin or older fingers report better results when the same finger is enrolled from multiple angles, which is a free fix if reads feel inconsistent.

The USB-C emergency power port is a genuine convenience. If four AA batteries die at work, a phone or power bank can wake the lock and let you in, rather than paying a locksmith at midnight.
Rating is BHMA Grade 3 compliant with IP54 sealing from minus 22F to 158F, and four AA batteries are claimed at up to 12 months. Installation needs standard US screwdrivers and fits most standard deadbolts. Warranty is 12 months with lifetime phone support in the US.

What to check before you buy it
Understand that the app works over Bluetooth at close range only. If you want to unlock the door from another state, plan on the G2 gateway or accept that this is a local smart lock rather than a remote one.
Where it falls short
Ratings here land at 4.2 stars, and one-star reviews concentrate on missed fingerprint scans and app pairing trouble. Batteries are not included. Wi-Fi, Alexa and Google features all depend on the separately sold gateway.
8. eufy Security Smart Lock C30 – Best Minimal Setup
eufy Security Smart Lock C30, Keyless Entry Door Lock, Built-in Wi-Fi
Built-in Wi-Fi, no hub
4 AA batteries, 5 month claim
Keypad, app, voice and key
BHMA Grade 3, IP53
Pros
- Built-in Wi-Fi unlocks from anywhere with no bridge
- App pairing and setup are widely praised as painless
- No monthly subscription for remote access
- Modern finish and solid feel for the money
Cons
- Weakest rating here at 4.0 stars
- Weakest battery claim in the group at 5 months
- Touch keypad is hard to use in the dark
The C30 is the simplest connected option here. Four unlock methods, no fingerprint reader, and a radio in the lock so you can open the door from anywhere without a bridge sitting next to your router.
Setup is the selling point. Owners describe app pairing as close to painless, and the install is a claimed 15 minutes into most standard deadbolts with no drilling. There is no monthly fee attached to remote access, which is unusual for a connected lock.

It pairs with eufy Security doorbells so you can build combined routines, and unlock paths cover keypad, app, Alexa or Google Assistant voice, and a physical key that still works if the batteries die completely.
Certification is BHMA Grade 3 with IP53 sealing rated from minus 22F to 158F, and coverage runs 18 months. Auto-lock has a customisable countdown timer.

What to check before you buy it
This is the one to buy if fingerprints are not important to you and you mostly want app and voice control. Check that your existing ecosystem is eufy rather than Apple Home or Home Assistant, because there is no Matter support here.
Where it falls short
Battery life is the real problem. The claim is five months on four AA cells, and owners running multiple locks report depletion within weeks, with at least one lock failing outright with no low-battery warning. The touch keypad is also awkward to hit in the dark.
9. Veise VE017 Fingerprint Smart Door Lock – Best for Cold Climates
Veise VE017 Fingerprint Smart Door Lock with App Control, Matte Black
0.2 sec AI fingerprint
AES128 local encryption
4 AA, 12 month claim
Fits 38mm and 54mm bores
Pros
- Access credentials encrypted and stored locally
- Only lock here that fits both 38mm and 54mm bores
- Rated from minus 35F to 160F with IP55 sealing
- Unlimited one-time and recurring passcodes
Cons
- Remote locking and voice need the separately sold G1 gateway
- Door leaf must stay parallel to the frame during install
- No batteries included
The VE017 is rated from minus 35F to 160F, which makes it the pick if your front door takes a beating in winter or your keypad sits in a shaded north-facing entry. Fingerprint readers in cold weather are the reason many owners report failed reads, and a wider operating envelope helps.
The privacy story matters here too. Access records and credentials are encrypted with AES128 on the lock itself rather than sitting in a cloud account, which is the approach people who dislike cloud dependence tend to want.

Unlock methods number eight, including fingerprint, app, fob, code, code sharing, voice and mechanical key, plus five locking methods. Passcodes come in unlimited one-time, timed, permanent and recurring forms, and the auto-lock timer is settable from 0 to 180 seconds inside the app.
Four AA alkaline cells run about 12 months, with a USB-C emergency port and safe mode as backup. Two keys and two IC cards are included. Certification is BHMA and ANSI Grade 3 with IP55 sealing.

What to check before you buy it
This is the one lock here that fits a 1-1/2 inch (38mm) bore as well as 54mm, which matters if you live in older housing stock. Doors from 1-3/8 to 2 inches thick are supported. Keep the door leaf parallel to the frame during install or the latch will not seat.
Where it falls short
Remote locking and voice control need the Veise G1 gateway, which is not included. The app depends on Bluetooth range, meaning it works at the door rather than across the house. It also has the smallest review base in the group, so long-term data is thinner here.
10. Philips Wi-Fi Smart Deadbolt Lock – Best for Large Code Lists
Philips Wi-Fi Smart Deadbolt Lock, Keyless Entry Door Locks for Front Door
Built-in Wi-Fi, no hub
Fingerprint plus passcode
100 custom passcodes
Away Mode and access history
Pros
- Built-in Wi-Fi gives true remote unlock with no hub
- Up to 100 custom passcodes plus unlimited one-time codes
- Real-time alerts and full access history
- Away Mode restricts entry to the master code
Cons
- Wi-Fi limited to the 2.4 GHz band
- No door sensor so closed state is unknown
- Batteries not included
If you run a rental, a short-term property or a house where people constantly come and go, the code capacity here is the headline. One hundred custom passcodes plus unlimited one-time and scheduled codes means nobody waits for a key copy.
Five unlock methods cover app, passcode, fingerprint, physical key and voice. The radio is built in, so remote lock and unlock works without a hub, and the app shows real-time alerts alongside full access history.

Away Mode is the feature short-term hosts care about most. It disables all entry except the master code, so a lockout or a handover is one setting away from handled. Auto-lock is settable from 10 to 180 seconds.
Installation needs a screwdriver and fits doors from 1-3/8 to 2 inches thick. The unit is aluminum with a brushed finish and works with Alexa and Google Assistant voice control.

What to check before you buy it
Your network must be on the 2.4 GHz band, with the router within roughly 65 feet of the door. Use AA alkaline LR6 cells only, and note that batteries are not included.
Where it falls short
No door sensor is included, so the app cannot confirm the door is actually closed. Alexa unlocking asks you to speak the code aloud, which defeats the purpose on a front porch. It also carries the smallest review base here, just over 1,100 ratings.
What to Check Before You Buy a Smart Deadbolt Under 200 Dollars
The price ceiling in this category is not the constraint people expect. Most listings in this roundup sit well below 200 dollars, which means the real decision is whether you want a connected lock at all, and what it costs you in add-ons and batteries over five years.
Fingerprint, keypad, or both
A fingerprint reader is faster and removes PIN sharing entirely, which is why it shows up on eight of the ten locks here. It struggles with wet hands, cold fingers and dirt, so a keypad stays useful as a backup. A keypad-only lock has fewer failure points and nothing to recalibrate.
Built-in Wi-Fi versus a separate gateway
Built-in Wi-Fi means the lock talks to your router directly. Nothing else to buy, nothing else to power, but the radio draws more current and drains batteries faster. Bluetooth-only locks like the Veise RZ07 and DESLOC B200 manage the app at the door, and need a separately sold gateway before remote unlock or voice control works.
What still works when the internet is down
Every lock on this list keeps working through the internet, the app and the cloud, because codes and fingerprints are stored onboard. What you lose is remote unlock, push notifications and activity history. Physical key entry survives on all ten. This is worth knowing before you buy something that only feels smart when it has signal.
Battery chemistry and replacement cadence
Claims range from five months on the eufy C30 to 365 days on the TEEHO models, and 18 months on the ULTRALOQ over Thread. Owners report real numbers running shorter on high-traffic doors, sometimes by weeks. All of these run on AA cells, and only the eufy C220 includes them. Budget roughly a set of AA alkaline batteries each year as a maintenance cost rather than a one-time purchase.
Door thickness, bore size and hand
Most of these fit standard 2-1/8 inch (54mm) bores and doors from 1-3/8 to 2 inches thick. Two exceptions matter: the TEEHO TE002, TE001, KS02A locks are 54mm only, while the Veise VE017 also fits 1-1/2 inch (38mm). Several units auto-detect door hand on first power-up, which removes the most common install error.
How hackable are smart locks, really
Mechanical attack is the honest risk, and fingerprint or keypad entry removes the picking and bumping surface entirely. On the electronic side, the useful protections are local encryption and a physical key cylinder. The Veise VE017 encrypts access records on the lock with AES128 rather than in a cloud account. Keep firmware and app software current, use a random PIN of at least six digits rather than a birthday, and revoke guest codes the day someone leaves.
Who should buy which lock
A household with kids coming home alone should start with the fingerprint options. A landlord or short-term host should look at code capacity and expiring codes, which points to the Philips Wi-Fi Smart Deadbolt or the Veise RZ07. Someone in a cold climate should take the wide temperature rating on the VE017. If you rent and want a reversible install, pick a lock that sits inside the existing bore and leaves the door untouched, as our smart deadbolt picks for renters and apartments guide covers in more detail.
Frequently Asked Questions
What is the best budget smart door lock?
The TEEHO TE002 is the best budget smart door lock for most homes. It reads a fingerprint in 0.3 seconds, stores 20 prints and 20 passcodes, holds both auto-lock and a one-touch lock, and runs on four AA batteries for a claimed 365 days. It needs no hub, no app and no subscription.
What is the best smart door lock for value?
The TEEHO TE001 offers the best value. It carries 20 access codes plus a one-time guest PIN that deletes itself after a single use, an auto-lock adjustable from 10 to 99 seconds, IP54 weather sealing and two backup keys, with a claimed 365 day battery life on four AA cells. It has no connectivity at all.
What is the best door lock with both a keypad and fingerprint sensor?
The TEEHO TE002 combines a keypad, a fingerprint reader, one-time PINs and two physical keys in one bolt. It is BHMA Grade 3 certified, IP54 rated for weather, and installs with a screwdriver into a standard 2-1/8 inch bore without drilling.
Which brand of smart lock is the most reliable?
Reliability tracks the design more than the badge. TEEHO models lead on owner-reported multi-year use, and the ULTRALOQ Bolt SE carries BHMA certification with an IP65 rating and lifetime mechanical coverage. Owners frequently single out Schlage Z-Wave deadbolts for keypad capacity and physical key backup, though those sit above this budget ceiling.
Do smart locks work without wifi?
Yes for entry. All ten locks here store codes and fingerprints on the lock itself, so keypad, fingerprint and physical key entry keep working with no internet, no app and no hub. You lose remote unlock, push notifications and activity history when the connection is down.
How long should batteries last in a smart lock?
Claims run from five months on the eufy C30 to 365 days on the TEEHO models and up to 18 months on the ULTRALOQ over Thread. High-traffic doors drain faster, and Wi-Fi use costs more than Bluetooth or Thread. Most of these locks take four AA cells and only the eufy C220 includes batteries.
Which Smart Deadbolt Should You Buy
The TEEHO TE002 is the best smart deadbolt under 200 dollars for the widest set of households, because fingerprint entry, a keypad and a physical key all work without a hub, an app or a monthly fee. If you want remote unlock without buying a bridge, the ULTRALOQ Bolt SE is the connected pick, with Matter over Thread support for Apple Home and an 18 month battery claim on that radio. For a rental or a house where people rotate constantly, the Philips Wi-Fi Smart Deadbolt handles one hundred custom passcodes and Away Mode.
Check the bore size before anything else, since that is the mistake that sends a lock back. If you want to read more budget-tested gear this year, our smartwatch picks under 200 dollars and dehumidifier picks under 200 dollars follow the same approach.
