The Fingerprint Door Lock replaces traditional keys with four convenient entry methods — fingerprint, keypad password, IC card, and mechanical key backup — giving every household member and guest a flexible way to get in without sharing a physical key. The upgraded fingerprint sensor recognizes prints in under 0.5 seconds with a high accuracy rate that eliminates the frustrating false rejections common in older biometric locks. It stores up to 100 fingerprints and 50 passwords, making it practical for families, home offices, rental properties, hotels, and apartments where multiple people need reliable access. A USB port on the exterior allows emergency power via a power bank if the internal batteries run low, so you’re never locked out.
Installation requires no drilling or rewiring — it fits wooden doors between 1.18 and 1.97 inches thick, works on both left and right swing doors, and comes with all necessary tools and video tutorials to guide you through the process in minutes. One important first step: you must register an administrator fingerprint before any other setup, as the lock will accept any fingerprint until an admin is configured. Once set up, it delivers a clean, keyless entry experience that’s both more secure and more convenient than a standard door knob. A straightforward smart home upgrade that works for bedrooms, offices, and anywhere you want controlled, keyless access.
