Smart Fingerprint Door Lock

Smart fingerprint door lock with integrated handle design that combines a digital lock and door lever for added convenience, eliminating the need for a separate handle. It features 4-in-1 unlocking options including fingerprint, passcode, mobile app control, and mechanical key, allowing flexible access for family, guests, and temporary visitors with one-time or custom codes. The fingerprint sensor provides fast 0.3-second recognition, while the auto-lock function can be set between 5 to 60 seconds after the door closes for added security. Built for durability, it has passed up to 100,000 usage cycles and 2000N pressure resistance testing, supporting both residential and commercial use. It is easy to install with only a screwdriver required, fits most standard doors with 60–70mm backset and 35–50mm thickness, and works on both left and right-handed doors.
