Understanding Your Master Key System

A Master Key System is a key plan whereby selected keys can open a number of pre-defined doors. Basically, it’s a system that allows two or more keys to open one lock. Master key systems have a series of locks that are individually keyed but having the added benefit of an overriding master key that can lock and unlock the entire series. With a traditional Master Key System, you need locks and keys that are the same make and model, then the locks must be rekeyed. The basic pin tumbler master locks use a master wafer/pin in between the key pin and the driver pin.

Most master key systems work in a hierarchical way, providing various levels of access and control for a secure site. For example, an apartment building owner can unlock all doors and locks however the tenant can only unlock one door. Or in a commercial working environment like an RSL club or licensed premises, a manager/employee will have one key that gives them access to the building, their office and perhaps a filing cabinet depending on responsibilities.

Keyed Alike Systems is an arranged number of locks, setup to be operated by the same key; many locks operated by one key. This is the most basic type of master key system.

Level 2: Master Key System (MK)

Master Key Systems are used when there are a number of locks each having their own individual key, and also a key that will operate all the locks which are the master key. Using this system, holders of individual keys may open those locks that they are authorised to operate, while those in charge may open all the locks.

Level 3: Grand Master Key System (GMK)

A Grand Master Key System is an extensive system that requires locks to be master keyed in groups, with a master key to operate all locks within its own group but no other group and has a grand master key which will operate all locks in every group. Thus, people may be authorised to operate individual locks only, all locks in a group, or all locks within the system according to the need of the user.

Level 4: Great Grand Master Key System (GGMK)
