4KS is a maximum security lock system that uses patented technology to eliminate key bumping and minimise intruders’ ability to tamper with, pick, or bypass the lock.
Hardened metal elements provide exceptional resistance to drilling, impact, or barrel-pulling attacks.
The key is reversible meaning it can be inserted either way making operation simple. The 4-curve design incorporates additional security ensuring the system is suitable for deployment in the largest and most complex master key systems. Unlike most master key systems that rely on spring pressure in the cylinder, the 4KS sliders (locking pins) inside the cylinders are actively moved by the tracks in the key. This active operation means 4KS will perform well in challenging environments be they dirty, dusty or salty.
