Designed for the user

Whether in your own home, in a football stadium, a hospital or a commercial office environment, security and safety are a key consideration. CES locking systems provide only the highest levels of security through precision engineering and protection from duplication.

Master keyed locking systems are relevant if you want to lock many doors with one single key. Master keyed locking systems can also serve as an organisational tool since they allow the implementation of hierarchically structured access authorisations.

A locking system should be planned in close cooperation between the developer and the planning office. Only this will ensure that an ideal locking plan structure is found which affords the flexibility to make changes and extensions even years after its initial installation. These specific requirements determine what type of locking system is installed.

All CES master keyed locking systems are patent-protected and comply with the most stringent DIN/EN requirements, as well as
being approved by the BSI with their 3 star Kitemark.

Even the largest and most complex of buildings can be managed systematically. Apart from the grand master key, which can operate all the cylinders in the locking system, group master keys, group keys and sub-group keys deliver various hierarchical levels, as the building requires.
