AI Verdict
A 3-in-1 biometric door knob with Tuya app control and 0.5-second fingerprint recognition, best for internal doors needing basic access management.
This lock is a situational fit, primarily due to its Bluetooth-only app control and zinc construction. It provides convenient biometric access for internal doors or low-security external doors, but its reliance on Bluetooth means you won't get remote Wi-Fi functionality without a separate Tuya gateway. The 508 DPI fingerprint sensor and 100-fingerprint storage are solid for its price band.
If you need true remote access and better security for a main entry, look for smart locks with integrated Wi-Fi and a higher security rating, often indicated by ANSI/BHMA certifications.

Dimension Scores
The 508 DPI fingerprint sensor boasts a 98% recognition rate within 0.5 seconds, which is above average for budget locks.
Connectivity is limited to Bluetooth for app control, restricting remote access and management to within close proximity of the lock.

Constructed from zinc, the material is average for a budget lock, but its weather resistance for outdoor exposure is not specified.
Best For

- Office doors within a home or small business.
- Apartment unit doors where a simple biometric solution is needed.
- Airbnb hosts managing access for guests with temporary codes (if using a Tuya gateway for remote access, not specified for this product).

Watch Out For

- While it fits door thicknesses from 1-3/8" to 2-3/16", you must verify your door size to avoid installation issues.

What Buyers Say
Users frequently highlight the straightforward installation process, often mentioning it only takes a few minutes with the included screwdriver. The multiple unlocking methods, especially the fingerprint and app options, are consistently praised for convenience. However, the Bluetooth-only app control is a recurring point of discussion, as it limits true remote management. Some feedback on similar Tuya locks points to the app's learning curve for initial setup, particularly when adding new fingerprints.
“Honestly, it was super easy to put on my bedroom door, and the fingerprint thing works like a charm, but I wish I could unlock it when I'm not home without buying extra stuff.”
Common Praise
- Installation is quick and only requires a screwdriver.
- Fingerprint recognition is fast, unlocking in under 0.5 seconds.
- The ability to store 100 fingerprints is useful for multiple users.
- Having both fingerprint and app unlocking means no more fumbling for keys.
- The mechanical key backup provides peace of mind for battery failures.
Common Complaints
- The Tuya app can be confusing for setting up fingerprints.
- Bluetooth range limits app control to close proximity, not true remote access.
- Requires 4 AA batteries that aren't included in the box.
- Concerns about the security level for main entry doors compared to more robust smart locks.
Ownership Tips
- Battery life can vary significantly based on usage frequency.
- The fingerprint sensor might require a few attempts for consistent recognition if fingers are wet or dirty.
- The silent mode setting in the app is useful for quiet entry and exit.
- The adjustable latch makes it adaptable to different door backsets without extra hardware.
Frequently Asked Questions
Does this lock require a Wi-Fi connection?
No, the lock connects to your phone via Bluetooth for app control. While some Tuya devices can use Wi-Fi, this specific model's app features are managed over Bluetooth.
How many fingerprints can this door lock store?
It can store up to 100 sets of fingerprints.
What happens if the battery dies?
You can use the included mechanical key as a backup to unlock the door in case of battery exhaustion.
Is installation difficult?
Installation is designed to be easy and takes minutes with the included screwdriver, fitting most standard single-cylinder US doors without extra drilling.
Can I manage user access remotely?
You can manage users and view access records through the Tuya app when you are within Bluetooth range of the lock. For remote management outside of Bluetooth range, a separate Tuya Wi-Fi gateway would typically be required, which is not included or specified for this product.
Buying Guide
When you're looking at a fingerprint door lock, you need to think about where it's going. Is it for your bedroom, an office, or your front door? This determines how much security and what kind of remote access you actually need. Don't just assume 'smart' means it does everything; check the connectivity type. Bluetooth locks need you to be nearby, while Wi-Fi locks offer true remote control, often at a higher price.
Control: App (Bluetooth)
This means you control the lock with your phone, but only when you're close enough for a Bluetooth connection, like how your headphones connect to your phone. If you want to unlock the door when you're miles away, this won't do it on its own.
Fingerprint Sensor: 508 DPI, 0.5s recognition
DPI (dots per inch) indicates the sensor's resolution, higher means more detail, like a camera. 508 DPI is a good resolution for accurate fingerprint reading. The 0.5-second recognition means it unlocks almost instantly, similar to unlocking your smartphone.
Material: Zinc
Zinc is a common metal for door hardware. It's durable enough for indoor use but might not hold up as well against harsh outdoor weather or determined forced entry attempts compared to heavier-duty metals like stainless steel.
Alternatives
If you need remote Wi-Fi access or higher security for an exterior door, look for smart locks with integrated Wi-Fi, a keypad for code entry, and a higher security grade rating.
