Master key systems explained…

Basic master key systems comprise of a Master Key which passes a group of locks, each with its own separate ‘differ’ key.
A larger group of locks may require dividing, into departments for example, and each departments’ locks would have a separate ‘sub’ master key which would pass the locks in that department but not the locks in other departments.
Our master key systems would of course still pass all locks in all departments.

Examples of our Master Key Systems

Example 1

A block of 12 flats has a master key which passes all locks, tenants would be issued with a key that operated their individual flats but each tenant key would also pass a ‘common’ cylinder fitted to the external entrance door to the flats. Another key may be allowed to access the main entrance and a Cleaners cupboard only.

Example 2

A High School has six departments and ten buildings. The site manager requires one master key that passes all locks. He requires six sub master keys, each one passing locks in the relevant department. Each classroom has its own ‘differ key’
Sub Master Keys are issued to the relevant Department Head and ‘differ keys’ are issued to teachers so that they have a key to their own classroom.
Separate keyed alike locks still passing the master key are fitted to Cleaners Cupboards, another keyed alike set to Store Cupboards.
Main entrance doors are fitted with keyed alike locks which remain outside of the main master key systems due to the consequences of a master key being mislaid or stolen. In these circumstances, only the outer door cylinders would need to be changed, making our master key systems one of the most efficient type of key system available.
