demand for a reversible key system was predominantly driven by Switzerland. The other systems, such as MCS, were not reversible key systems and 3KS, unfortunately, did not catch on in Switzerland. That's good

And in the years after that we were continually developing innovative locking systems, such as GPI, MCS, ICS, 3KS plus, electronic authorisation for master key systems was introduced, and finally, we launched

towards innovative security solutions such as the EMZY electronic motorised cylinder, the impressive MCS magnetic code system or the ­AirKey and Xesar electronic access systems. Hier geht’s zur EVVA Academy

The tried and tested magnetic technology is still popular despite 3D printing. A milestone in EVVA's history, which still offers an unparalleled level of security and is 100% copy proof.
