The 3KS 3-curve system stands out due to its unique, patented, springless operating principle. Unlike conventional locking systems, in the 3KS cylinder the locking elements move along the curves on the key and are not driven against a spring force. The technology in detail: 12 solid, springless locking pins are brought into specific positions via positive control of the 6 key curves and are scanned via 2 control bars. A locking bar in the plug controls the key's cross-section profile.
