- Patent protection until 2035
The 4KS cylinder is equipped with several locking sliders. Thanks to the freely moving locking elements in the plug, it is virtually impossible to scan the cylinder in order to make a copy key. The springless function also protects against bumping.
The hard metal control bars which also provide a body drilling protection in the 4KS cylinder offer effective protection against drilling..
The hard metal control bars and the modular version (SYMO) offer effective protection against pulling and snapping attempts.
The 4KS options make it possible: External key override cylinder function; Classroom and SOS function; dust protection; free-wheel function; cogwheel cam and much more.
As a reversible key with unique rounded tip, the 4KS key is particularly easy to use. The high-quality nickel-silver alloy of the key, the anti-friction coating of all locking elements and the springless technology of the 4KS plug guarantee high wear resistance even under the toughest conditions. The special feature of the 4KS key, however, are the overlapping curve millings. It practically rules out key manipulation within the locking system. The additional coding also provides highest security.
4KS is patented, springless and anything but conventional. In contrast to other locking systems, the locking elements in the 4KS cylinder are sliding along the curve millings on the key. No force is needed to insert the key due to lacking spring resistance. A total of 12 springless, solid locking pins are brought into specific positions via positive control of the 6 curves milings on the key and are scanned via 2 control bars. A locking bar in the plug controls the key’s additional coding. The 4KS key is scanned a total of four times and therefore offers the highest security.
