DISEC MR500F-25D1 – Keyed Alike Pair of Magnetic Euro Cylinder Protectors
The DISEC MR500F-25D1 Keyed Alike pair comprises 2 magnetic security protectors for Euro profile cylinder locks, configured with identical magnetic coding so that both can be operated using the same keys. The set includes 6 KM0P3GMR magnetic keys, each capable of unlocking either protector. This arrangement simplifies access management when protecting two doors without requiring separate magnetic keys.
Keyed Alike configuration – One magnetic key system for two doors
KA (Keyed Alike) means that both magnetic protectors have the same magnetic coding. Any of the six supplied magnetic keys can unlock either protector, regardless of which door it is installed on.
This configuration is particularly useful for a main entrance and a secondary entrance or two access doors within the same property. Keyed Alike operation applies exclusively to the magnetic security protectors: the existing Euro cylinder locks continue to operate with their own mechanical keys.
Magnetic protection and anti-pull mechanism
Each MR500F-25D1 features a rotating magnetic keyhole cover that restricts direct access to the cylinder. The matching magnetic key releases the protective cover, allowing the normal Euro cylinder key to be inserted and operated.
Each device also incorporates a self-adjusting spring-loaded anti-pull plate designed to improve resistance to removal attempts, together with anti-drilling protection for the fixing screws. Both protectors retain the mechanical and dimensional characteristics of the standard MR500F-25D1 model.

Lock compatibility and installation
The MR500F-25D1 protectors are designed for compatible Euro cylinder locks with 38 mm M6 fixing centres. Before installation, check the cylinder position, fixing-hole alignment, installation depth and external clearance on both doors.
The Keyed Alike configuration does not change the protector dimensions or mounting arrangement. Therefore, both locks must be compatible with the MR500F-25D1 model.
Before ordering: verify the 38 mm M6 fixing centres and nominal 25 mm height for both installations. The pair is supplied with matching magnetic keys. Contact Matteoda customer service for technical assistance, orderable finishes and estimated delivery times.
