The Art of Master Key Systems

Master keying is the complex process of setting up a master key system. Each lock within a system is rekeyed to work with its own key and a master key. It is one aspect of key management solutions that ensures access for authorized people.

How Master Key Systems Work

Master key systems are not just a way to keep your keychain from getting too heavy. They are the best example of smart, modern, and efficient security. With these systems, a single key can open more than one lock, but each lock still has its own key. A master key system is the stuff of dreams for property managers, business owners, and people who work in security.

The Hierarchy in Key and Access Control Systems

The Singular Role of Individual Keys

Getting to basics, individual or change keys work only with one lock. It is the most basic key and does not work in other locks or give you entry to anything else. It is the simplest solution for people who want the simplest security without the complex structures.

Master keys can open a set of predetermined locks, which makes it easier to keep track of keys in places with more than one lock. They put all the different features of each key under one cover, which is safety and convenience.

Grand Master Keys: The Apex of Key Management

The grand master key is at the top of the key hierarchy. This key means full access because it can open multiple groups of locks. Each group may have its master key. The grand master key is the best example of efficient and hierarchical key and access management for complex systems and buildings.
