This smart door handle lock integrates multiple access methods into a compact unit designed for interior doors. It combines a biometric fingerprint sensor, a backlit keypad, RFID key cards, and Tuya Bluetooth app control, along with two traditional backup keys. The lock is constructed with a zinc alloy housing and a durable polycarbonate keypad cover, offering resistance to daily wear. The fingerprint module uses a semiconductor sensor that can store up to 20 fingerprint profiles, enabling quick recognition. The keypad supports up to 50 user codes, while the RFID function accepts up to 20 cards.

All electronic components are powered by 4 AA batteries (not included), with a low-battery indicator to prompt timely replacement. The lock mechanism features a standard latch bolt compatible with most interior door preparations, and installation requires only a screwdriver. The product operates via the Tuya Smart app over Bluetooth, allowing users to manage access codes, check lock status, and enable one-time or timed passwords remotely when within range. No hub is needed for Bluetooth operation. The lock body measures approximately 6.3 inches in height and 2.8 inches in width, with a backset adjustable to 60mm or 70mm, fitting door thicknesses from 35mm to 45mm.

The lever design is ambidextrous and can be flipped to suit left or right-handed doors. The finish is a smooth matte black coating that resists fingerprint smudges. The lock is rated for indoor use, suitable for bedrooms, home offices, or storage rooms where keyless convenience is desired. In terms of daily performance, the fingerprint sensor offers consistent reading under dry conditions, while the keypad provides tactile feedback.

The RFID cards operate at a standard 13.56MHz frequency and are compatible with most existing card-based systems. The Bluetooth app interface is straightforward, supporting user management and activity logs. The backup keys operate a traditional lock cylinder for emergencies. The lock’s rated operating temperature range is -10°C to 55°C, ensuring stability in typical indoor environments.

The overall build feels solid, with no noticeable play in the lever after installation. This lock presents a practical solution for households needing flexible entry methods without complex wiring. It is priced affordably, delivering a combination of biometric, keyless, and mechanical access in one unit. The straightforward installation and simple daily operation make it a suitable choice for homeowners or renters looking to upgrade interior door functionality.
