This fingerprint smart door lock combines a sturdy zinc alloy construction with a smooth brushed finish, offering reliable keyless entry for exterior doors. It operates through capacitive fingerprint recognition, a backlit keypad, and a physical key override, ensuring access in various conditions. The lock’s motor-driven latch retracts quietly and quickly, with a response time under 0.5 seconds. The fingerprint sensor is embedded in the handle, allowing one-step unlocking. The keypad features a scratch-resistant surface and supports up to 50 user codes. The interior handle includes a twist knob for quick egress and a manual lock/unlock switch. The lock body is built with reinforced metal gears and a weather-resistant coating, suitable for both indoor and outdoor installations. It runs on four AA batteries, with a low-battery indicator and an emergency micro-USB port for backup power. The installation process fits standard door prep (2-1/8 inch borehole, 1-1/2 inch backset) and requires no wiring. This model is designed for wood, metal, or fiberglass doors between 1-3/8 and 2 inches thick. It supports passage mode and auto-lock mode, configurable via the keypad. The overall build quality emphasizes durability and consistent performance over time. There is no need for smartphone integration or app setup, making it a straightforward replacement for existing locksets. The price point at just over one hundred dollars positions it as a practical upgrade for households seeking enhanced security without complex installation. The tactile feedback from both keypad and fingerprint sensor is precise, minimizing failed attempts. The handle’s ergonomic curve fits a natural grip, and the lock body’s compact design does not interfere with door swing. This electronic lock is intended as a primary entry solution for front or side doors, suitable for residential use. It does not rely on Wi-Fi or Bluetooth, so there is no risk of network interference or hacking. The power consumption is low, with an average battery life of roughly 8 to 12 months under normal use. The fingerprint storage uses capacitive technology, which is less affected by dry or wet fingers compared to optical scanners.

This product delivers fundamental smart lock capabilities with robust physical components and straightforward operation.
