Maximum intrusion resistance and flexibility in a master key system

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 outperform all others in challenging environments be they dirty, dusty or salty.

When organisations require maximum intrusion resistance and flexibility in a master key system, they choose 4KS.

When it comes to performance in challenging environments, the active sliders and springless design in 4KS provides an edge that is unmatched by other systems. As a key is inserted, most master key systems rely on small springs to push the locking pins into place. Even small amounts of dust, dirt or grit can affect the operation of the cylinder. Thanks to the 4KS springless design, when the key is inserted into the cylinder, the sliders (locking pins) are actively moved into place by the tracks of the 4KS key. This provides industry leading operation and reliability in the harshest of environments.

It is extraordinarily difficult to reverse engineer 4KS.
Moreover, 3 separate systems guard against key tampering and illicit copying by staff, visitors or contractors.

As a reversible key with unique rounded tip, the 4KS key is simple to use. The high-quality nickel-silver alloy of the key, the teflon coating of all locking elements and the springless technology of the 4KS cylinder guarantee high wear resistance even under the toughest conditions. The special feature of the 4KS key is the overlapping curve technology. It practically rules out all forms of manipulation within the locking system and the use of dealer profiles greatly enhances security.
