This smart fingerprint door lock integrates a fingerprint scanner, digital keypad, and app-based control into a single handle set designed for front door use. The lock body is constructed from zinc alloy with a matte black finish, providing resistance against corrosion and everyday wear. The fingerprint sensor uses semiconductor technology to capture and authenticate prints quickly, with a recognition speed typically under 0.5 seconds. The keypad is backlit for visibility in low light and supports up to 20 user codes. Through the accompanying mobile app, users can remotely lock or unlock the door, generate temporary access codes for guests, and view entry logs. The auto-lock feature can be programmed to engage automatically after a set delay, enhancing security without manual intervention. The deadbolt mechanism is motor-driven and operates quietly, with a manual thumb turn on the interior side for emergency override. Installation is designed to fit standard door preparations (2-3/8 or 2-3/4 inch backset) and requires only a screwdriver; the included mounting hardware and step-by-step guide simplify the process. The lock runs on four AA batteries, and a low-battery warning will alert users through the keypad beeps and app notification. A backup mechanical key is also provided for power-out situations. The electronic components are sealed against dust and moisture, suitable for covered entryways. The overall feel is solid and responsive, with no noticeable lag during operation. This model offers a balance of convenience and reliability at a very affordable price point, making it accessible for homeowners seeking to upgrade to keyless entry without complicated wiring or subscription fees. The combination of multiple access methods—fingerprint, code, app, and key—ensures flexibility for households with different user preferences. The matte black finish blends with most modern door styles, and the handle provides a comfortable grip. While it is not a high-end smart lock with Wi-Fi bridge or voice assistant integration (it uses Bluetooth for app connection), it performs consistently for daily use within typical home range. The auto-lock delay can be set to 10, 30, or 60 seconds, and the keypad automatically locks after five incorrect attempts to prevent brute-force guessing.

This keyless entry deadbolt offers practical smart features and dependable hardware execution at a consumer-friendly cost.
