Notice: If you connect the door lock directly via mobile Bluetooth, it can only be operated within 10 meters of the lock. Affected by walls and other obstructions, the actual usable range may be shorter. To control the lock remotely without distance limitation, you need to connect the device through a smart gateway.

4 Flexible Unlock Options

Choose from 4 convenient access methods: Biometric fingerprint scan, anti-peep password, physical backup key, and Bluetooth APP unlock (compatible with Tuya & Smart Life), to fit different daily scenarios.

Ultra-Fast Fingerprint Access

Powered by advanced biometric technology and smart chips, the lock recognizes fingerprints in under 0.5 seconds for instant, one-touch entry.

Anti-Peep Fake PIN Protection

The decoy password function lets you input random numbers before/after your real PIN, hiding your actual code from prying eyes and boosting home security.

Remote & Temporary Access Control

Grant access to guests, family, or cleaners via the Tuya/Smart Life APP. Generate one-time or time-limited temporary passcodes, so visitors never have to wait outside.
