The Magnetic Defender Disec MRM39 for Dierre Cylinder Locks offers absolute security and protection for Dierre armored doors. It is installed on the exterior side of the armored door and acts as an impenetrable shield, protecting the cylinder and the internal lock mechanism.

Controlled Key Duplication: Duplication of magnetic keys can only be carried out at authorized stores upon presentation of the ownership card.
