Four entry methods: Use fingerprint, PIN code, smartphone app, or mechanical key access for families, children, elderly members, and frequent visitors. 0.3-second fingerprint recognition: Fingerprint unlocking takes 0.3 seconds, entry takes 1 second, and the lock supports access for up to 50 users. Bluetooth app setup: Connect by Bluetooth to add users, set permissions, and monitor access logs; remote control requires pairing with a Gateway sold separately. 5–59-second auto-lock: The lock secures the door 5–59 seconds after closing, while mute mode supports quiet entry for late-night returns. Aluminum alloy security body: The lock has aluminum alloy construction, IP54 weather resistance, anti-peeping code protection, and a solid lock cylinder. 2-1/8-inch door-hole fit: The deadbolt suits 2-1/8-inch (54mm) holes, not 38mm holes, and installs with a screwdriver on standard US left- or right-handed doors.
