Keys are easy to lose, forget or hand over to someone else.
A fingerprint smart door lock offers a much more convenient way to get into your home. Instead of searching through your pockets for keys, you simply place your finger on the sensor and unlock the door.
But modern fingerprint smart locks can do much more than biometric unlocking.
Depending on the model, you can also get:
- Fingerprint access
- PIN codes
- Smartphone control
- Temporary guest codes
- Remote locking and unlocking
- Auto-locking
- Activity history
- Apple Home support
- Alexa and Google Home compatibility
- Mechanical key backup
- Emergency USB power
- Built-in Wi-Fi
- Facial recognition
- NFC access
For this guide, we compared popular fingerprint smart locks available through major online marketplaces and looked at fingerprint capacity, reliability, connectivity, battery life, security features, backup access and installation requirements.

What Is a Fingerprint Smart Door Lock?
A fingerprint smart lock is an electronic door lock that uses biometric recognition to identify an authorized fingerprint.
Instead of inserting a key, you touch the fingerprint reader.
The lock compares the fingerprint with the registered fingerprints stored in its system.
If there’s a match, the lock releases the mechanism.
Many models also provide alternative ways to enter the home.
For example:
Fingerprint → Unlock
PIN → Unlock
Phone → Unlock
Physical key → Unlock
This redundancy is important because no electronic lock should depend on only one method of entry.
What Should You Look for in a Fingerprint Smart Lock?
Before buying one, don’t focus only on the fingerprint scanner.
There are several other things that matter.
1. Fingerprint Recognition
A good fingerprint reader should recognize an enrolled finger quickly and consistently.
Look for information about:
- Recognition speed
- Recognition accuracy
- Number of fingerprints supported
- Local fingerprint storage
- Wet or dirty finger performance
Remember that manufacturer accuracy figures are controlled specifications, not a guarantee that every user’s finger will work perfectly every time.
2. Backup Entry
This is extremely important.
Imagine your lock battery dies while you’re outside.
A good smart lock should provide at least one backup option.
Depending on the model, this could be:
- Mechanical key
- Emergency USB power
- PIN code
- NFC card
- Smartphone
- External battery connection
The best locks provide multiple options.
3. Battery Life
Smart locks are battery-powered, so battery life matters.
Depending on the lock, you may get several months of operation from a set of batteries.
Some newer models are beginning to address battery maintenance in creative ways.
The DESLOC V150 Plus, for example, uses an integrated low-light solar panel combined with a 10,000mAh battery.
4. Remote Access
Remote access allows you to control or monitor your lock when you’re away.
This can be useful for:
- Airbnb hosts
- Family members
- Cleaners
- Contractors
- Employees
- Deliveries
- Rental properties
However, remote access usually requires Wi-Fi, a hub or another internet-connected component.
5. Door Compatibility
This is one of the most important things to check before buying a smart lock.
A fingerprint lock may be excellent but completely useless if it doesn’t fit your door.
Check:
- Door thickness
- Backset
- Cross-bore diameter
- Deadbolt type
- Door material
- Lock orientation
- Existing cylinder
- Mortise configuration
Some popular smart locks are designed specifically for American-standard deadbolts.
If your door uses a European-style multipoint lock, mortise lock or a common Nigerian security-door configuration, the installation requirements may be completely different.
Never order a smart lock until you’ve measured your door.
#5 — eufy Smart Lock Touch & Wi-Fi
Best for: Families that want fingerprint access and multiple users
The eufy Smart Lock Touch & Wi-Fi is a straightforward fingerprint smart lock that combines biometric access with traditional smart-lock features.
The Wi-Fi version supports fingerprint access, keypad entry, smartphone control and physical-key backup.
eufy’s specifications list support for up to 100 users on one account, Bluetooth, 2.4GHz Wi-Fi and a BHMA Grade 2 certification. The lock is designed for doors approximately 35–55mm thick, with supported 60mm or 70mm backsets.
Fingerprint access
eufy says the fingerprint reader can correctly recognize a registered fingerprint up to 98% of the time when the finger is positioned correctly.
That’s useful because the entire point of a fingerprint lock is quick access without entering a code every time.
Other access methods
You can use:
- Fingerprint
- Keypad
- Smartphone
- Physical key
That makes the lock practical for households with multiple people.
Security
The lock carries a BHMA Grade 2 certification, and eufy says it has been tested through 250,000 locking and unlocking cycles.
Battery
The lock uses four AA batteries.
eufy lists approximately 6 months to one year of battery life depending on usage.
Potential downside
The biggest issue for international buyers is compatibility.
eufy specifies particular door dimensions and recommends against steel doors for this model.
That means you should measure your door before ordering.
Best for
Families looking for a relatively straightforward fingerprint smart lock with multiple user access.

#4 — Lockly Secure Pro
Best for: Multiple ways to unlock your door
If you don’t want your smart lock to depend entirely on fingerprint access, the Lockly Secure Pro is an interesting option.
Lockly has built its smart locks around multiple access methods, including fingerprint recognition, keypad entry, smartphone access and physical keys.
The Secure Pro can store up to 99 fingerprints, according to Lockly’s current support documentation.
That makes it especially useful for:
- Large families
- Rental properties
- Shared houses
- Small offices
- Guest accommodation
Fingerprint system
The Lockly fingerprint system requires several scans when registering a new fingerprint.
According to Lockly’s instructions, a fingerprint is scanned six times during registration to create the biometric profile.
Once registered, users can access the lock with their fingerprint.
Why multiple entry methods matter
Suppose someone forgets their fingerprint isn’t working.
They can use another method.
Or perhaps a guest doesn’t need permanent fingerprint access.
You can provide a temporary code instead.
This makes a smart lock much more flexible than a traditional key.
Potential downside
Lockly’s product range includes several versions, and features differ between models.
Before purchasing, verify:
- Exact model
- Wi-Fi support
- Fingerprint capacity
- Door compatibility
- Included accessories
- Remote access requirements
Don’t assume every Lockly model has exactly the same features.
Best for
People who want fingerprint access but also need several alternative entry methods.

#3 — ULTRALOQ U-Bolt Pro WiFi
Best for: A traditional deadbolt-style fingerprint lock
The ULTRALOQ U-Bolt Pro WiFi is one of the better-known fingerprint smart locks for people who want a familiar deadbolt format combined with modern access technology.
The U-Bolt Pro WiFi has a built-in Wi-Fi chip, meaning an additional ULTRALOQ Bridge isn’t required for Wi-Fi connectivity.
It also supports fingerprint access, Bluetooth and smart-home integrations.
Fingerprint capacity
ULTRALOQ’s current 2026 support documentation says the U-Bolt Pro WiFi supports up to 50 users, with each user able to register one code and two fingerprints.
That’s plenty for most households.
Smart-home integration
The current U-Bolt range supports platforms including:
- Alexa
- Google Assistant
- SmartThings
- IFTTT
ULTRALOQ’s documentation also distinguishes between models with built-in Wi-Fi and versions that require the separate Bridge.
Door sensor
One useful feature is support for a door sensor on the U-Bolt Pro WiFi.
That means the system can know whether the door is actually closed rather than simply assuming the lock has been operated.
Why we like it
The U-Bolt Pro WiFi is attractive because it combines:
- Fingerprint access
- PIN codes
- Smartphone control
- Bluetooth
- Wi-Fi
- Physical-key backup
- Door-status monitoring
- Smart-home integration
It’s a good example of a smart lock that doesn’t force you to use just one method of entry.
Potential downside
Again, door compatibility is the biggest consideration.
A smart lock designed for a standard deadbolt may not fit a non-standard security door.
Before buying, measure your existing lock.
Best for
Homeowners who want a conventional deadbolt-style lock with fingerprint access and built-in Wi-Fi.
[Check Price on AliExpress →]
#2 — Aqara Smart Lock U100
Best for: Apple Home and smart-home enthusiasts
The Aqara Smart Lock U100 is one of the most feature-rich fingerprint smart locks in this comparison.
It combines biometric fingerprint access with a touchscreen keypad, Apple Home Key, NFC, smartphone control and a traditional mechanical key.
Aqara says the fingerprint reader has a 98.6% recognition rate, recognition time of less than 0.5 seconds, and local storage for up to 50 fingerprints.
That’s an impressive combination.
Apple Home Key
One of the U100’s biggest selling points is Apple Home Key.
If you use a compatible iPhone or Apple Watch, you can tap your device against the lock to unlock the door.
Aqara says Home Key can even work when the Apple device has run out of power, subject to Apple’s supported power-reserve functionality.
For Apple users, that’s extremely convenient.
Multiple Entry Methods
The U100 supports a wide range of unlocking methods.
These include:
- Fingerprint
- Password
- Apple Home Key
- Aqara Home
- Google Home
- Alexa
- NFC card
- Aqara integrations
- Mechanical key
Aqara’s documentation lists nine unlocking methods.
This makes the U100 much more versatile than a basic fingerprint lock.
Temporary Passwords
This is particularly useful for guests and rental properties.
The U100 supports:
- Permanent passwords
- Periodic passwords
- One-time passwords
Aqara also supports phantom passwords, which allow additional digits to be entered around the actual password to make it harder for someone watching you to identify the real code.
Security and Durability
Aqara lists the U100 as meeting the BHMA Level 3 structural standard and gives the exterior keypad an IP65 rating.
The fingerprint data is stored locally, and Aqara says sensitive data is protected using 128-bit AES encryption.
Battery Life
The U100 uses four AA batteries.
Aqara lists an average battery life of approximately eight months, based on its laboratory test conditions.
It also includes a USB-C emergency power option if the batteries run out.
Potential downside
The U100 is primarily designed around an American-standard deadbolt.
Aqara lists support for 60mm and 70mm backsets and door thickness of approximately 35–55mm.
That makes measuring your door extremely important before ordering.
Also, while basic functions can work directly over Bluetooth, Aqara says a compatible Aqara hub is required for certain remote features and smart-home automations.
Best for
Apple users and smart-home enthusiasts who want one of the most feature-rich fingerprint locks available.

#1 — DESLOC V150 Plus
Best overall fingerprint smart lock
The DESLOC V150 Plus is one of the most interesting new smart locks to emerge in 2026.
Why?
Because it combines several technologies that traditionally required separate products.
You get:
- Fingerprint recognition
- 3D facial recognition
- Built-in Wi-Fi
- Smartphone control
- Automatic locking
- Mechanical keys
- USB-C emergency power
- A large rechargeable battery
- Integrated solar charging
DESLOC introduced the V150 Plus at CES 2026 as part of its new flagship smart-lock lineup.
Why the Solar Charging Matters
Battery maintenance is one of the biggest annoyances with smart locks.
If your lock runs on batteries, eventually you’re going to have to replace or recharge them.
DESLOC takes a different approach.
The V150 Plus has an integrated perovskite solar panel designed to harvest energy from sunlight and ambient light.
The company says it is designed to continue charging even in low-light and shaded conditions.
That doesn’t mean you’ll never need to charge the battery.
Instead, the solar system is designed to reduce how frequently you need to do it.
Fingerprint + Face Recognition
The V150 Plus isn’t just a fingerprint lock.
It also includes 3D facial recognition with liveness detection.
For fingerprint access, DESLOC uses what it calls a GPT curved fingerprint sensor.
The lock can store up to:
- 50 fingerprints
- 50 faces
according to DESLOC’s current product specifications.
That gives you several convenient ways to enter your home.
Built-In Wi-Fi
Another advantage is that the V150 Plus has built-in Wi-Fi.
DESLOC says no separate gateway is required.
Through the DESLOC app, users can:
- Manage access
- Check lock status
- Receive notifications
- Review activity records
- Control the lock remotely
- Set automatic locking
That makes the lock particularly attractive for people who don’t want to build an entire smart-home hub ecosystem just to operate their front door.
Large Battery
The V150 Plus includes a removable 10,000mAh battery.
DESLOC says it can provide more than eight months of normal use without solar charging, depending on usage.
It also includes:
- USB-C emergency power
- Two mechanical keys
So even if the battery becomes completely depleted, there are backup options.
Outdoor Protection
The exterior assembly is rated IP65, and DESLOC lists the lock as meeting BHMA Grade 3 security and durability requirements.
That makes it more suitable for an exterior entry door than many indoor-only smart locks.
Potential downside
The V150 Plus is a relatively new and sophisticated product.
That means it isn’t the obvious choice for everyone.
It’s also considerably more expensive than basic fingerprint locks.
And, as with every smart lock in this guide, you need to make sure the lock is physically compatible with your door before ordering.
Best for
Homeowners who want the newest combination of fingerprint access, facial recognition, Wi-Fi and low-maintenance solar-assisted power.

Fingerprint Smart Lock vs. Keypad Smart Lock
Is fingerprint access really necessary?
Not always.
A keypad lock can be perfectly convenient.
Here’s the difference:
| Feature | Fingerprint Lock | Keypad Lock |
|---|---|---|
| Fingerprint access | Yes | No |
| PIN access | Usually | Yes |
| Physical key | Usually | Usually |
| Phone control | Many models | Many models |
| Guest codes | Many models | Many models |
| No code to remember | Yes | No |
| Sharing access | Fingerprint/code | Code |
| Wet/dirty hands | Can affect scanner | Usually unaffected |
Fingerprint access is particularly convenient for people who enter and leave frequently.
You don’t need to remember a PIN or take your phone out of your pocket.
Are Fingerprint Smart Locks Secure?
A fingerprint lock can be very convenient, but it’s important to understand what biometric access actually does.
The fingerprint reader is primarily an authentication mechanism.
The physical security of the lock still depends on:
- Lock construction
- Deadbolt strength
- Door construction
- Strike plate
- Installation
- Cylinder design
- Security standards
- Software security
- Access management
A premium fingerprint reader doesn’t automatically make a weak door secure.
For the best result, the entire door system needs to be secure.
What Happens If the Fingerprint Doesn’t Work?
This is why backup entry methods matter.
Your finger might fail to register because:
- It’s wet
- It’s dirty
- Your finger is damaged
- The scanner is dirty
- The battery is low
- The fingerprint wasn’t registered correctly
A good smart lock should therefore provide another method.
Depending on the product, this could be:
PIN + mechanical key
or:
Fingerprint + phone + PIN + key
The more reliable backup methods you have, the better.
Smart Lock Installation: Measure Your Door First
This section is particularly important if you’re buying from an international marketplace.
Before ordering, measure your existing door.
Door Thickness
Measure the thickness of the door.
Many popular smart locks support doors in the range of approximately 35–55mm, but this varies by model.
For example, Aqara lists 35–55mm for the U100, while eufy lists the same general range for its Touch models.
Backset
The backset is the distance from the edge of the door to the center of the lock hole.
Common sizes include:
- 60mm
- 70mm
But don’t assume.
Measure your own door.
Cross-Bore Diameter
Some locks require a specific hole diameter.
Again, this is especially important with American-style deadbolts.
Door Type
Ask yourself:
Do I have a standard deadbolt?
Or:
Do I have a mortise lock?
Or:
Do I have a multipoint security door?
This distinction can determine whether the smart lock can be installed at all.
Important for Nigerian Buyers
If you’re buying a fingerprint smart lock in Nigeria, don’t simply choose a model because it has good reviews on Amazon or AliExpress.
The electrical side isn’t the main concern with smart locks because they’re battery-powered.
The bigger issue is physical door compatibility.
Many popular models from Aqara, eufy and ULTRALOQ are designed around particular deadbolt dimensions.
A typical Nigerian security door may use a different lock body or multipoint locking mechanism.
Before purchasing:
- Take photos of your existing lock.
- Measure the door thickness.
- Measure the backset.
- Measure the lock-hole diameter.
- Identify whether it’s a deadbolt or mortise lock.
- Check the manufacturer’s compatibility chart.
- Ask the seller if the exact model fits your door.
If possible, have a locksmith inspect the door before you spend money on an expensive smart lock.
Fingerprint Smart Locks for Airbnb and Rental Properties
Fingerprint locks can be useful for rental properties because you don’t necessarily need to hand guests a physical key.
However, fingerprint access isn’t always the best option for short-term guests.
A temporary PIN may be more convenient.
For example:
Guest arrives Friday → temporary PIN active Friday–Sunday
Guest leaves Sunday → PIN automatically expires
Some smart locks support temporary or one-time passwords.
The Aqara U100, for example, supports permanent, periodic and one-time passwords.
This can be more practical than registering and later deleting every guest’s fingerprint.
Fingerprint Smart Locks vs. Traditional Keys
Here’s a simple comparison.
| Feature | Traditional Lock | Fingerprint Smart Lock |
|---|---|---|
| Physical key | Yes | Usually backup |
| Fingerprint | No | Yes |
| PIN | No | Usually |
| Phone control | No | Many models |
| Remote access | No | Some models |
| Guest codes | No | Many models |
| Activity history | No | Some models |
| Auto-lock | Mechanical | Yes |
| Battery required | No | Yes |
| Smart-home integration | No | Some models |
Traditional locks are still reliable and inexpensive.
Smart locks simply provide more convenience and control.
How Long Do Smart Lock Batteries Last?
Battery life depends on:
- Number of daily unlocks
- Wi-Fi usage
- Bluetooth usage
- Auto-lock settings
- Temperature
- Battery type
- Fingerprint scanner activity
- Other features
For example, Aqara lists an average of approximately eight months for the U100 under its test conditions.
eufy lists approximately six months to one year for its Touch model.
DESLOC takes a different approach with its 10,000mAh rechargeable battery and solar-assisted charging.
Don’t treat any manufacturer’s battery-life number as a guarantee.
Your actual experience can be different.
Which Fingerprint Smart Lock Should You Buy?
Here’s the simple breakdown.
Choose the eufy Smart Lock Touch & Wi-Fi if:
You want a straightforward fingerprint lock with support for many users and Wi-Fi connectivity.
Choose the Lockly Secure Pro if:
You want lots of alternative access methods and support for up to 99 fingerprints.
Choose the ULTRALOQ U-Bolt Pro WiFi if:
You want a traditional deadbolt-style fingerprint lock with built-in Wi-Fi and smart-home integration.
Choose the Aqara U100 if:
You’re an Apple user or want a feature-rich smart-home lock with Apple Home Key, fingerprint access and multiple password options.
Choose the DESLOC V150 Plus if:
You want the newest combination of fingerprint recognition, facial recognition, Wi-Fi and solar-assisted battery management.
Final Verdict
Fingerprint smart locks are becoming much more capable.
The best models aren’t simply replacing a key with a fingerprint scanner.
They’re turning your front door into a connected part of your smart home.
The eufy Smart Lock Touch & Wi-Fi is a practical option for families.
The Lockly Secure Pro stands out for its large fingerprint capacity and multiple entry methods.
The ULTRALOQ U-Bolt Pro WiFi is a strong choice if you want a traditional deadbolt-style smart lock.
The Aqara U100 is particularly impressive for Apple users and smart-home enthusiasts.
But our overall pick is the DESLOC V150 Plus.
Its combination of fingerprint access, 3D facial recognition, built-in Wi-Fi, 10,000mAh battery, USB-C emergency power and integrated low-light solar charging makes it one of the most interesting fingerprint smart locks of 2026.
However, there’s one piece of advice that’s more important than choosing the right brand:
Make sure the lock actually fits your door.
A smart lock with incredible features is useless if your door requires a different lock mechanism.
Measure first, then buy.
