What Is a Master Key? What You Need to Know

A master key system is a sophisticated security solution commonly used in larger organizations to provide multiple levels of access control. Understanding how master keys work can help you better grasp their significance in various settings.

What is a Master Key?

A master key is a specialized key that can open several different locks within a master key system. These locks are related in some way, allowing for hierarchical access control. For instance, in corporate office buildings, individual keys may be assigned to different departments, while a master key grants access to all areas of the building. To determine if your locks are part of a master key system, consult your builder, strata council, or property manager.

How Does a Master Key Look?

Visually, a master key resembles any other key, with grooves cut to fit specific locks. However, what sets a master key apart is its ability to operate locks with additional pin configurations. These locks, known as master-keyed locks, contain extra pins that respond to both individual keys and the master key.

How Does a Master Key Work?

A master key operates master-keyed locks by utilizing a third pin called the master wafer. This unique configuration allows the master key to unlock the lock, providing access beyond what individual keys can achieve.

Can You Duplicate a Master Key?

Master keys are protected by patents, preventing them from being sold or copied at hardware stores or commercial locations. However, authorized key providers can duplicate master keys with proper authorization, ensuring security and control over key distribution.
