What are protected keys?

 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.
