# EVVA MCS Locking System

> High-security lock cylinder using magnetic rotors and dual mechanical coding.

EVVA MCS (Magnetic Code System) is an ultra-high-security mechanical cylinder lock designed to resist non-destructive picking and unauthorized key duplication. It pairs four permanent samarium-cobalt magnetic pills in the key with eight internal freely rotatable magnetic rotors and two mechanical profile tracks. Because the magnetic rotors operate contactless and cannot be deciphered via visual inspection or standard 3D printing, it is widely considered one of the most secure mechanical locking systems available.
