Magnet codiertes Schliesssystem

MCS. 100% key copying protection

Security featuring technical excellence

Thanks to the worldwide unique MCS security, MCS master key system operators need not worry about any issues. This is firstly down to keys' 100% copying protection and secondly, a result of the system's vast calculation security levels. Reserves can already be integrated when planning the master key system. Consequently, your facility can continue to grow and MCS grows with it.

Your MCS benefits

  • Protected against 3D printing
  • For challenging master key system structures
  • Very high protection levels against burglaries
  • Patent protection until 2035 at the latest
    (according to EP3221536. For country-specific patent protection, see


MCS cylinder

MCS cylinder

The MCS cylinder contains eight freely rotating magnet rotors to the left and right of the key channel and each one is assigned to one of the four magnet pills on MCS keys. The magnet rotors are brought into a locking position using keys with access authorisations. Mechanical components arranged above grant permission to unlock components.

The MCS key

The MCS key combines no less than two technologies for triple security: One magnetic and two mechanical encoding features. The eight-stage magnetic key scanning takes place via the four magnet pills, permanently magnetised in different magnetic alignments on either sides. Mechanical encoding also achieves unparalleled security with its precise length profile as well as additional, mechanical encoding features.

The MCS design key

MCS keys are optionally available in the colours black, red, blue, white, yellow and green. The colour coding helps to differentiate between keys.

Picking and scanning protection

The freely rotating magnetic motors of MCS cylinder is separate from the key channel and can therefore not be scanned or manipulated. This means that the magnetic coding in the MCS cylinder cannot be scanned.

Drilling protection

The hard metal elements in the MCS cylinder plug offer effective protection against drilling.

Protection against pulling and snapping

The hard metal elements and their modular design (SY-MO) provide a high level of protection from plug pulling and snapping attempts.

Security card

Key copies, additional cylinders and lock charts are available from authorised EVVA Partners, providing the relevant proof of legitimacy only, i.e. the EVVA security card.

Patent protection until 2035 at the latest

All EVVA products are available at authorised EVVA Partners only. EVVA is authorised to take legal steps against any kind of patent infringements. Patent protection until 2035 at the latest.

Technical protection thanks to the required specialist expertise

The technical features of an MCS key require extensive specialist knowledge and specialist machinery during production. This makes it extremely difficult to illegally copy keys.
