APP Fingerprint Cylinder Smart Door Lock with Keypad

Secure, Keyless Access for Modern Homes & Apartments

Enjoy flexible, keyless entry with this APP Fingerprint Cylinder Electronic Smart Door Lock. Designed for home and apartment doors, it combines fingerprint recognition, keypad codes, key cards, mobile app control, and traditional keys in one adjustable cylinder lock. Manage access for family, guests, and tenants directly from your smartphone while keeping installation simple and non-destructive to your existing door.

Featuring a built-in fingerprint reader, this lock lets you unlock the door in seconds using your fingerprint, providing a highly reliable and convenient way to enter. The digital keypad allows you to create unique PIN codes that can be shared with trusted people, ideal for rentals, Airbnb, or visiting friends and service providers. A key card option adds another quick tap-to-unlock method. Through the Tuya app (iOS and Android), you can manage users, set codes, and view unlock records, so you always know who accessed the door and when.

When paired with the optional G2 gateway, the lock can connect to Wi‑Fi and work with Alexa or Google Home in supported regions, enabling voice control such as locking or unlocking via your smart speaker. Bluetooth support allows local app control even without Wi‑Fi. In case of low battery, you can still open the door with the included mechanical keys or use an emergency USB power supply to power the lock temporarily from outside. The adjustable-length cylinder is designed to fit most standard doors, making it suitable for new installations or easy replacement of an existing cylinder without drilling or changing the door body.
