Smart Biometric Fingerprint Door Knob with App Control

Key Features of the 3-IN-1 Smart Door Knob

3 Unlock Ways Our smart door knob supports three different unlock methods: fingerprint unlock, remote control via an app, and emergency backup keys. This multifunctional design makes it a reliable keyless entry solution.

Rechargeable & Emergency Unlock No need to frequently replace batteries! Our Bluetooth lock is rechargeable through a Type-C cable. When power is low, simply charge the smart lock to unlock. Additionally, it comes with an emergency spare key for reliable unlocking. Note that this device supports Bluetooth connection via the app, requiring Wi-Fi and a gateway for full functionality.

Easy Installation Installing the fingerprint door knob is quick and straightforward. Using a screwdriver, you can set it up in just a few minutes. It fits most US doors and can be easily integrated with existing locks. Detailed installation steps and videos are available for your convenience. The supported door thickness is 35-55mm, and the distance from the door edge to the handle hole should be 60-70mm or adjustable.

Smart and Safe Technology The biometric fingerprint lock recognizes your fingerprint in just 0.5 seconds. It stores up to 20 fingerprints and allows sharing of up to 20 access codes with family members. Once unlocked with a fingerprint, the door will automatically lock in 5 seconds, ensuring security even in a hurry. The interior thumb turn switches to normal mode, making it easy to use.

Smart App Control Our smart lock comes with a free app, TUYA SMART APP, which allows you to add fingerprints, check unlock records, monitor battery levels, and set auto-lock, passage mode, and privacy mode for added convenience and security. Your fingerprint data and in-app information are stored locally, enhancing privacy and security.
