Notes About This Item:
This is in a factory sealed box
Notes from Amazon: This smart door lock knob offers three unlock methods: fingerprint, app control, and backup keys, providing versatile keyless entry. Note that fingerprint setup via the app is required before using the fingerprint function. For emergency power or charging, use a USB-A to Type-C cable; Type-C to Type-C cables are not compatible.
The lock features a security design with passage, entrance, and privacy modes, easily switchable via the thumbprint. These modes enhance privacy and control access, ideal for bedroom doors.
Installation is straightforward, requiring only a screwdriver and fitting most US door thicknesses (35 to 55mm). The product includes detailed installation instructions and videos.
A built-in 400mAh rechargeable battery powers the lock for 8-12 months on a full charge, which takes 4-6 hours. It supports only USB-A to Type-C charging and not fast charging. The lock includes a visual power display and low-battery alarm. The battery is non-removable, and battery life may vary with usage.
The smart app enables fingerprint management, unlock record viewing, auto-lock settings, and mode selection within Bluetooth range. For offline operation, fingerprint revocation and reconnection are necessary."
