Multiple protection as standard

Vertical pin pairs and optional side locking elements check the robust nickel silver key and allow the barrel to turn when the shear line is reached.
The patented centering pin protects the lock cylinder against the bumping method.
The overlapping key profile provides protection against the picking opening method.
Hardened steel elements in the barrel and in the housing make it difficult to drill or pull the lock cylinder.

Even more security available, if desired

You can choose a lock cylinder with 4 or 5 tumbler pins – for even greater protection against impressioning.
Optional steel security elements protect the lock cylinder.
Optional sacrificial cut: In the event of attempted manipulation by pulling the lock cylinder, it breaks off at a pre-defined point, and cannot be opened with conventional tools, like a screwdriver. It can still still be opened with the corresponding key in an emergency.
Additional options such as cylinder covers

You design your master key system.
All options are available to you

AP2000 can be used with all serial keying and master key system types – from the one-key-for-all solution for home use, from simple to complex master key systems with different access authorizations. The basis is a key plan, according to which selected keys can open a series of specific doors. To design the key plan, we examine and evaluate our 
customers’ requirements in detail. This means better control, saving costs incurred by duplicate keys and reducing the total number of keys.

Free choice of lock cylinders

The cylinder programme features a wide variety of types to choose from. You can also integrate, for example, cyl for cabinet locks, key-operated switches or lift controls into the system. Choose between nine surface finishes to harmonise your design.

Added value for your master key system.
Useful special functions
