Since their foundation in Vienna, Austria in 1919, EVVA has grown to become one of the world’s largest manufacturers of keying systems.
EVVA’s name derives from a drive for invention, experimentation and application that has underpinned its reputation as a leader in the development of ground-breaking security technology.
It is extraordinarily difficult to reverse engineer 4KS. Moreover, 3 separate systems guard against key tampering and illicit copying by staff, visitors or contractors.
When a user inserts their key, 2 control bars in the cylinder scan 6 curves etched into the 4KS key and bring 12 solid, springless locking pins into specific positions. An additional bottom bar checks the edge profiles of the key. The 4KS key is scanned 4 times during the unlocking action — 3 times more than other systems. Only when all of these match up does the locking plug release.
The original 4KS key is produced exclusively by EVVA to increase system security. Distribution of the key blanks is tightly controlled with keys only available through certified dealers of EVVA 4KS.
Suitable for the most harshest environments, simple key alike systems, small Restricted Key systems through to large complex multi level Restricted Key systems.
EVVA EPS is not a simple pin-tumbler system. EPS employs unique, patented features to harden it against lockpicking, drilling and key bumping, as well as making key theft and illicit duplication more difficult. At the front of the cylinder more hardened steel pins provide additional intrusion-resistance.
In addition, multiple broaching sidebars (providing a theoretical 133 million combinations) enable authorised EVVA dealers to develop and install large multi-tiered hierarchies
of thousands of locks with a very low probability of phantom keys. All cylinders are made from brass, stainless steel and nickel components to deliver maximum operational lifespan.
