EVVA keys are protected in several different ways to ensure unauthorised key copying is as difficult as possible:
1. Technical & technological key protection
EVVA locking systems are developed in the in-house design department and meet very high technical standards. They can only be manufactured using specially constructed machines.
2. Managed key protection
Only authorised key holders are able to order new keys from EVVA or an EVVA partner. A security card supplied with the cylinder upon purchase is used to identify such key users.
3. Legal key protection
All EVVA locking systems and key profiles are patented.
