Stainless Steel Mechanical Door Lock - Keypad - Keyless - Deadbolt with Handle - Complete Set.

Keyless entry door lock with mechanical deadbolt and stylish interior design, compatible with most doors with a thickness between 30mm and 65mm.

Mechanical and waterproof: This keypad lock operates on a mechanical principle and requires no batteries, for added peace of mind. No more complicated programming and nuisance alarms.

High quality and more durable material: The stainless steel lock body is extremely hard (grade 304), making it very difficult to force. Made of 304 stainless steel with reinforced anti-corrosion surface treatment, it provides 5-15 times more durability than other materials.

Enhanced pass-through function: A special lock switch, located inside near the door handle, allows the retractable bolt to remain retracted after opening, allowing the door to close without locking.This avoids frequent access problems and prevents electronic automatic locking systems from being triggered accidentally.

Easy installation: a simple screwdriver is enough for installation, without additional wiring or drilling. The keyboard is wear-resistant, leaves no traces for burglars and offers enhanced security.
