This keyless entry door lock integrates multiple access methods into a single, durable unit designed for residential and commercial use. The exterior is constructed from a zinc alloy and stainless steel combination, offering resistance to physical impact and weather exposure. The fingerprint sensor employs semiconductor technology for rapid recognition, storing up to 100 unique fingerprints. It supports 20 access codes and includes two physical keys as a backup. The lock body houses a quiet motor that operates the latch smoothly, and the entire assembly meets ANSI Grade 2 security standards for basic residential and light commercial security. Power is supplied by four AA batteries, which provide an average of 8 months of normal use, with a low-battery indicator on the exterior panel.

Functionally, the lock operates through three primary modes: fingerprint, keypad code, and mechanical key. The fingerprint sensor reads the user’s fingerprint within 0.3 seconds under normal conditions, even if the finger is slightly wet or dry. The backlit keypad allows for code entry in low light, and the lock can be programmed to accept a temporary code for guests or service personnel. The auto-lock feature can be set to engage after a delay of 10 to 99 seconds, ensuring the door is always secured after entry.

Additionally, a passage mode allows the lock to stay unlocked for extended periods when needed. The internal mechanism is built with precision components that maintain consistent performance over thousands of cycles, and the unit is rated for temperatures between -20°C and 50°C, making it suitable for indoor applications in various climates. The lock is designed to fit standard North American door preparations, with an adjustable latch depth of 60mm or 70mm, and a backset of 60mm or 70mm. It fits doors with thickness ranging from 35mm to 55mm. Installation requires only a screwdriver and approximately 15 minutes, as the mounting plate and wiring are pre-assembled. The finish is a matte black coating that resists fading and corrosion. Quality control during production includes individual testing of each sensor and motor before packaging, which contributes to a low failure rate in the field. The lock’s circuit board is sealed to protect against humidity and dust, though it is not rated for outdoor use under direct rain.

The product balances reliable daily performance with an affordable price point, making it a practical choice for property owners seeking to upgrade from traditional keyed locks.
