This double sided keypad door knob integrates a dual-cylinder design with a key alike system, offering both keyless entry and traditional key access for enhanced flexibility.

Constructed from corrosion-resistant zinc alloy and reinforced thermoplastics, the lock body undergoes rigorous durability testing to ensure long-term performance in varied environments. The electronic keypad supports up to 20 user codes, enabling customized access for family or frequent visitors without compromising security. Its weatherproof and waterproof rating (IP65) protects internal components against rain, dust, and UV exposure, making it suitable for outdoor installations such as gates, fences, swimming pool enclosures, and interior doors. The dual-cylinder mechanism allows independent locking from both sides, while the key alike feature means all included keys operate the same lock, simplifying key management for multi-point installations. Operation is powered by four AA batteries (not included), with a low-battery indicator to prevent lockouts. The touch-sensitive keypad responds reliably even in wet or gloved conditions, and the backlight helps in low-light settings. The finish is a durable matte coating that resists fingerprints and fading. This lock emphasizes practical security without requiring Wi-Fi or app connectivity, reducing potential electronic failures. Installation is straightforward with standard door preparations, and the lock fits doors 1.375 to 2 inches thick. The overall build prioritizes consistent functionality across temperature extremes, with a tested operating range of -20°C to 60°C. For homeowners seeking a reliable, no-frills smart lock that combines mechanical backup with keypad convenience, this model provides a balanced solution for both residential and light commercial use. The affordable price point makes it an economical upgrade for multiple doors while maintaining essential security features.
