A master key system comprises an unlimited number of cylinders locking in different ways, all of which are opened by a master key. Master key systems are used in private homes, stores, storerooms, garages, and cloakrooms in public buildings of all kinds such as schools, hospitals, theatres, lidos, sports facilities and records offices.
These systems can be considered for premises such as administration and industrial buildings, hotels, hospitals, airports, universities, etc.
A general master key system is divided into separate main groups, groups and sub-groups, with corresponding central and individual locking to comply with an organization scheme prepared for a specific range of application (locking concept). The object of the system is to define the areas of responsibility clearly and unambiguously.
