How Does a Master Key System Work?

The way a master key system works depends on the locks and the keys. Locks are usually of the pin-and-tumbler design where the key notches push the pins in the lock upwards, successfully unlocking it. The locks involved in master key systems are made in such a way that they work with more than one key. The design of the lock and the keys are essential in creating master key systems.

There are different keys involved in a master key system, which allows people in different levels and positions to get access to particular areas of the property only.

  • Change Key

The change key, which is also referred to as “sub-master key,” can only open one lock and other locks that are similar to it. The lock that the change key opens can be opened by the master key and other higher-ranking keys.

  • Master Key

Some properties have the master key as the highest-ranking key. If the master key didn’t exist, there would only be one key for a lock. The master key is necessary so that you can still open the lock even if the change key gets lost.

  • Grand Master Key

A grand master key is even more significant than a master key because it can open more than one master key system. Because it can open different master key systems, this includes change keys within the same system.

  • Great Grand Master

The great grand master key opens all the grand master key systems, so it can be used to open basically everything within the property or the building.

Maintenance staff and landlords don’t need to have a heavy ring of keys to be granted access.

3. Increased efficiency

Having only one or several keys for an enormous property will save everybody time when a particular room has to be opened. Landlords can access all the apartments should it be required.
