The unique magnetic keys guarantee maximum key copying protection. The system has three different safeguards that protect against keys being copied or tampered with:
Managed protection EVVA or EVVA Partners only make keys for authorised individuals with required proof of entitlement, such as a security card.
Legal protection Keys are manufactured for sale by EVVA only. What's more, EVVA protects against unauthorised manufacturing of MCS keys by means of patented features on the key.
Technological protection Keys have technological features such as permanent magnetisation, which require specialised machines for their manufacture. Illegal manufacture is, therefore, virtually impossible.
