This keyless entry smart deadbolt lock integrates a keypad, fingerprint touchscreen, and mobile app control into a single secure access solution.

Constructed from durable zinc alloy and hardened steel, the exterior housing resists tampering and weather exposure, while the precision‑machined internal components deliver consistent performance over extended use. The matte black finish provides a sleek, modern appearance that complements various door styles without attracting fingerprints or smudges. The lock supports multiple authentication methods, including high‑sensitivity capacitive fingerprint recognition, a backlit numeric keypad, and Bluetooth‑enabled app operation. Fingerprint scans process in under one second, and the keypad accommodates up to 50 unique user codes for family members or office staff. Through the dedicated mobile application, users can remotely grant temporary access codes, monitor lock status, and review entry logs. The auto‑lock function engages the deadbolt automatically after a preset interval, enhancing security without manual effort. Installation requires only a screwdriver and follows a straightforward process compatible with standard US door preparations. The lock fits doors between 1.38 and 2 inches thick, and the retrofit design allows replacement of most existing deadbolts without additional drilling. Both front and rear assemblies align securely, and the included mounting hardware ensures a stable fit. This versatility makes the lock suitable for residential entrances, rental properties, or small office doors. The smart deadbolt operates on four AA batteries, with low‑battery alerts sent via the app and an emergency external USB‑C port for temporary power. Data transmission is encrypted, and the touchscreen remains responsive under various lighting conditions. At a price of $36.00, this unit provides a practical balance of smart features and robust construction, making it a cost‑effective upgrade for users seeking basic connected access control without recurring subscription fees.
