Technology - 3KS (3 Curve System) works with a unique and patented system that requires no springs. Unlike conventional locking systems, in the 3KS cylinder the locking elements move along the curves on the key and are not pushed against a spring force.

During the locking action, the 3KS key is scanned a total of 4 times – this is three times more than with other systems. The springless locking pin function guarantees utmost wear resistance and protection against picking. This technology means that there are reams of variations for cylinder master key systems.

How does the e-primo differ from the locking cylinder in your house or apartment door?
