A master key system is when one key can open a variety of different areas in a building, for example this could be used for a manager to have access to every single door or area of a site. In additional to this, a master key system can allow individual employees to have access to specific areas of a business whilst restricting others. For example, the image below shows that the grand master key can open all of the locks in the system. Whereas the key holder for Master Key 1 can only open all of the locks in group A and group B, and the key holder of sub master C will only be able to open these locks throughout the system. For example a finance officer can have access to a front door of the building, a finance office, and the archive room which is limited to other staff.
Master Key systems have a variety of benefits, it provides convenient access without the need of carrying round a bunch of keys, it is easy to identify who has access to what area in the organisation, and additional locks can be added without having to have new keys made!
