Dimension Scores
The fingerprint recognition rate is stated at 98% with a 1-second unlock time, though some users report occasional issues with wet hands.
Connectivity is limited to Bluetooth, restricting app control to short range and lacking Wi-Fi for remote access.
The app allows for fingerprint and code management, and viewing unlock records, but lacks broader smart home integration.
Constructed from zinc material, it's suitable for interior use but lacks specific weather resistance ratings for outdoor applications.
Best For
- Securing interior rooms like bedrooms, home offices, or storage closets.
- Apartment dwellers needing a keyless entry solution for individual rooms.
- Users who frequently forget keys but need quick, personalized access.
- Small offices or private spaces requiring access control for up to 50 users.
Not Recommended For
- Exterior doors requiring robust weather resistance or advanced security features like a deadbolt.
- Users needing Wi-Fi or smart home hub integration for remote access beyond Bluetooth range.
- Environments where hands are frequently wet, potentially hindering fingerprint recognition.
- Anyone who prefers not to manage physical backup keys outside the secured area.
Watch Out For
- The fingerprint sensor sometimes struggles with wet hands; one user reported needing to wait for hands to dry post-shower before it would recognize their print.
- Some users found the installation instructions to be out of order, making the setup process more challenging than expected.
- Initial fingerprint registration can be finicky; one user had to register their thumbprint four or five times at different angles for reliable recognition.
- The automatic relocking feature, while convenient, can lead to accidental lockouts if the emergency key is not stored externally.
- App control is strictly Bluetooth-based, meaning you cannot unlock or manage the lock when outside of Bluetooth range.

What Buyers Say
Many users found the installation process surprisingly quick, with some completing it in under 10 minutes, even without extensive instructions. The multiple unlocking methods, especially the fingerprint scanner, are frequently highlighted for convenience, though some experienced initial setup difficulties with fingerprint recognition. The Bluetooth-only app control is a recurring point, limiting its utility for remote management. The automatic locking feature is appreciated for security but also noted as a potential cause for accidental lockouts if not managed carefully with the physical key.
“This thing is pretty cool for my bedroom, but seriously, my hands gotta be dry or it just stares at me like 'who are you?' and the app only works when I'm practically hugging the door.”
Common Praise
- Installation is quick and straightforward, often taking less than 10 minutes.
- The fingerprint scanner provides fast access, recognizing prints in 0.1 seconds.
- The ability to mute voice prompts makes the lock operate quietly.
- The USB-C port for emergency charging is a practical backup if batteries die.
- The automatic relocking feature adds a layer of security, ensuring the door is always locked.
Common Complaints
- Fingerprint recognition can be inconsistent with wet or damp hands.
- The app's functionality is restricted to Bluetooth range, preventing true remote access.
- Instructions provided can be unclear or out of sequence, complicating setup for some users.
- Registering fingerprints sometimes requires multiple attempts and specific angles for reliable operation.
- The auto-lock feature, while convenient, can lead to users locking themselves out if the physical key isn't accessible.
Ownership Tips
- The fingerprint sensor's reliability decreases significantly if hands are even slightly damp.
- Battery life is generally long, but the low battery warning is crucial to prevent being locked out.
- The physical keys are essential to keep outside the room, especially with the auto-lock feature engaged.
- Managing multiple fingerprints and codes through the app is simple once the initial setup is complete.
- The lock mechanism itself is quiet, which is a plus for interior doors, especially if voice prompts are muted.
Frequently Asked Questions
Does this lock connect to Wi-Fi for remote access?
No, this lock connects via Bluetooth only, meaning you can only control it through the app when you are within Bluetooth range.
How many fingerprints can I store on this lock?
You can store up to 50 unique fingerprints on the lock for different users.
What happens if the batteries die?
The lock has a low battery reminder. If the batteries completely drain, you can use a physical key or connect a power bank via the Type-C emergency charging port to temporarily power it.
Is this lock suitable for outdoor use?
This lock is designed for interior doors like bedrooms, offices, or apartments and is not specified for outdoor use or weather resistance.
Can I install this myself?
Yes, it's designed for DIY installation on US standard doors, requiring no wiring or drilling, and fits both left and right-handed doors.
Buying Guide
When looking at a fingerprint door knob like this, you need to think about where it's going. It's a door knob, not a deadbolt, so it's best for interior doors where you want convenience and a bit of privacy, not maximum security for your front door. Understand that 'smart' here means Bluetooth, not Wi-Fi, so you won't be unlocking it from across town. Also, consider who will be using it – if they have consistently dry hands, the fingerprint reader will be a breeze.
Fingerprint Recognition Rate (98%)
This number tells you how often the lock is expected to correctly identify a registered fingerprint. A 98% rate means it should work almost every time, like a reliable key, but not perfectly every single time.
Connectivity (Bluetooth)
Bluetooth means the lock talks to your phone only when your phone is close by, typically within 30 feet. It's like using a remote for your TV – you have to be in the same room. If you want to unlock your door when you're not home, you need Wi-Fi.
Door Thickness (1-3/8'' to 2-1/8'')
This is crucial for installation. Just like buying clothes, if the size isn't right, it won't fit. Measure your door's thickness to ensure the lock can be properly mounted and function.
Alternatives
If this lock doesn't fit your needs, search for 'Wi-Fi smart deadbolt' for enhanced security and remote access, or 'weather-resistant smart lock' if it's for an exterior door.
