What is a Master Key System?

A master key system means that it is possible for people, who are authorised to access different doors within a system, to each have just one key.

Benefits for you:

  • Security with as few keys as possible
  • Easy use, as only one key is needed for all relevant doors
  • Simplified organisation
  • It is possible to define exactly who has access to which areas
  • All cylinder locks and types (main entrance doors, internal doors, garage doors…) can be locked with just one key

Example of a master key system:

Example: master key system (general main group key system) for an office building used by two companies, Smith Ltd. and Jones & Co.

  • GHS: The general master key locks all doors (e.g. for security guards)
  • HS 1 (Smith Ltd.): This master key locks all doors used by Smith Ltd. (e.g. for Smith Ltd.’s director)
  • 1G 1 (Smith Ltd.): In addition to locking the main entrance and the general staff areas (storeroom, toilet, kitchen), the 1st group key only locks Smith Ltd. offices 1 and 2 (e.g. for the clerical assistant)
  • 1G 2 (Smith Ltd.): The 2nd group key locks the main entrance, the general staff areas and all secretariat doors (e.g. for the secretary of Smith Ltd.’s director)
  • HS 2 (Jones & Co.): This master key locks all doors used by Jones & Co. (e.g. for Jones & Co.’s owner)
  • 2G 1 (Jones & Co.): The 1st group key only locks the doors of the sales areas, the main entrance and the general staff areas (e.g. for Jones & Co.’s sales staff)
  • 2G 2 (Jones & Co.): The 2nd group key locks the secretariat doors, the main entrance and the general staff areas (e.g. for the secretary)
