Master keyed lock systems forms
Master keyed lock systems can take many different forms.
For example, an office building leased by a company with some individual offices. Each of these offices can have its key. The master key would then have access to all of these offices and generally be held by the head of the company, management personnel, security staff, and/or the cleaner.
Then for a multi-level building, a grand master key provides access to all the doors in the building, and level master keys are created for each level which only accesses the doors on their respective level.
In other words, such as the following format:
- Grand Master Key: Access to all doors and locks in all departments and floor level
- Master Key: Access to a department or floor level
- Individual Key: Access to an office in a department or floor level
