3KS Schliesssystem mit 3 kurviger codierung

3KSplus. For the toughest conditions

Unbreakable security

You can rely on 3KSplus. Thanks to its high levels of resistance the system also locks and unlocks in the toughest conditions and even after years, it works like on the first day. This makes 3KSplusyour first choice for the toughest conditions – at high altitudes or in production facilities subject to high amounts of dirt. And not just that: 3KSplusalso provides excellent calculation features to even implement highly complex master key systems.


Your 3KSplus benefits

  • Resistant and extremely durable
  • For highly complex master key system structures
  • Springless technology
  • Patent valid until 2025



The 3KSplus cylinder

In contrast to other master key systems, the locking elements in the 3KSpluscylinder move along the curve key cuts on the key. It is no longer necessary to apply force against the spring resistance. A total of 12 springless, solid sliders are brought into a specific position via positive control of the six key curves and scanned by two control bars.


The 3KSplus key

As a reversible key the 3KSpluskey is particularly easy to use. The high-quality nickel-silver alloy and the anti-friction coating of all locking elements as well as the springless technology of the 3KSpluskey guarantee high levels wear resistance even in the toughest conditions. The special feature of the 3KSpluskey, however, is the overlapping curve key cuts. It practically rules out key manipulation within the master key system. The additional coding also guarantees highest security.

The 3KSplus design key

The 3KSpluskey is optionally available in the colours black, red, blue, white, yellow and green. The colour coding helps to assign keys to certain doors.

Picking and scanning protection

The 3KSplus-cylinder is equipped with several pins. It is not recognisable which pin is active in each case. With 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 cylinder bumping.

Drilling protection

The hard metal control bars and the body drilling protection elements as well as the body drilling protection in the 3KSpluscylinders offer effective protection against drilling.

Protection against pulling and snapping

Hard metal control bars, the drilling protection elements and its modular design (SYMO) offer effective protection against pulling and snapping attempts.

Security in its most complex form

3KSplus is frequently used in very large facilities with complex master key system structures and a high number of user groups. Why? 3KSplus provides excellent calculation features. Industrial companies, universities and large retail chains also benefit from the system's durability, convenience levels and the option to combine 3KSplus with EVVA electronic locking system components in one facility.
