Master key systems increase control and convenience

A master key system is a key can open a number of pre-defined doors. It helps maintain better control, saves key replacement costs and is convenient, as there are a lower number of keys in circulation. It also provides quick access to all rooms within the premises, e.g. for security staff and management personnel. This is not only convenient but can save lives in case of emergency.
In the above example, the ‘Grand Master Key’ would open all doors and lock types in the property . The “Financial master key” opens the account office and purchasing office, “Sales master key” open sales office and secretary’s office, “Warehouse master key” open the workshop and stores.

In addition, each employee has one key that opens the main entrance, their own office door and their filing cabinets.
