Master Key Systems

Benefits of a Master Key System

Master key systems will typically work off of a basic pin tumbler lock.

In a master key system, authorized personnel can be given a “Grand Master” key that can open every lock in the building. This grand master key replaces the needs for a large confusing key ring and makes it easier for property managers or building supers to make sure they can access any room they need.

About Master Key Systems

Simply put, a master key system is a method of securing large complexes, such as an apartment complex or an office building, in such a way that access to multiple points, by multiple people, can be organized and controlled.

Picture a Christmas tree. In master key systems, less powerful keys at the bottom are called “change keys”. Each one operates only one lock or one group of locks. The key at the top is known as the “master key”.

The simplest master key systems have two levels of keying and are considered the lowest level of master keying. Indeed, a master key system can be scaled to incorporate multiple “masters”. These are known as multi-level master key systems.

Take an apartment complex for example. All of the tenants might need access to the main lobby entrance, the laundry room and, of course, their individual apartments. For convenience, the lobby and laundry room might share the same key and each apartment its own key (change keys).

But what of the property manager, who may need access to all apartments as well as the lobby and laundry? This is where a master key system is both convenient but also secure. Rather than maintaining a key for each apartment, the property manager might be issued a “master” key allowing access to all apartment locks. When a new tenant moves in, there is no need to re-key every lock only the individual apartment.
