You’ve probably heard the term “master key system” before, especially if you own or manage a commercial property. For those who aren’t familiar, State Locks & Keys is here to explain. In simple terms, a master key is a key that opens all the doors for you. It may sound confusing. After all, how can just ONE key open several doors while another only gives you access to one? We’ll explain.
How Master Keys Are Ranked
Master key systems require you to have a key set consisting of several keys. However, each key in the set is different based on what they allow you to access and can be ranked on a system from “change key” to “grand master key.” Let’s discuss each kind of key.
The lowest ranking key in the system is called a change key, or sometimes a sub-master key. This key gives you access to only one lock and any locks that are identical to it. The lock that opens with the change key can also be opened with a master key and any key above that rank.
In some ranking systems, a master key is the highest-ranked key. Without a master key, each lock will have its own key. A master key will open all locks on a property.
Grand Master Key
There’s a key higher ranked than a master key? Yes! Grand master keys allow access to multiple master key systems. For facilities with several campuses or buildings that require their own key system, a grand master key will allow you to access the locks in all systems.
Great Grand Master Key
For businesses that require more than one grand master key system, you’ll need a way to unlock ALL the locks within the grand key systems. Theoretically, you could have a higher ranking key, but at that point, the systems get too confusing to keep track of.
