The Upgraded Fingerprint Smart Door Knob offers a modern, keyless solution for securing bedrooms, home offices, and apartments. This 3-in-1 lock allows for entry via biometric fingerprint, Bluetooth app control, or a traditional mechanical key for emergency backup. Finished in a sleek matte black, it features a versatile Passage, Privacy, and Silent Mode system, easily adjustable by a thumb turn to fit your specific lifestyle needs throughout the day.
Designed for convenience, the lock includes a built-in rechargeable battery that lasts up to one year on a single charge and can be powered up via a USB Type-C port. The accompanying app allows users to manage fingerprints, track access logs, and share entry permissions with family members within Bluetooth range. With a simple screwdriver-only installation and “low battery” notifications, this smart knob provides a reliable and stylish security layer for any interior or front door.
