Master Key Systems

Armstrong is recognised as the industry leader in Master Key systems. Master Key systems are used to allow or restrict access of different areas to different people.


What is a Master Key System?

A master key system is a key plan whereby selected keys 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.

For example, each employee has one key that opens the main entrance, their own office door and their filing cabinets. These keys work with different types of locks, e.g. door locks, cabinet locks, padlocks, etc., as long as the cylinder inside them is of the same model.
