Master Key Systems Explained: How They Can Simplify Security
Posted on 6th, Mar 2025
Security is a top priority for businesses, property managers, and even homeowners. One of the most effective ways to enhance security while maintaining convenience is by implementing a Master Key System. If you’re looking for a way to simplify key management and access control, this system might be the perfect solution.
At Locksmiths Perth 24/7, we specialize in designing and installing customized Master Key Systems for commercial and residential properties. In this guide, we’ll explain what a Master Key System is, how it works, and why it can be a game-changer for your security needs.
What is a Master Key System?
A Master Key System is a hierarchical keying system that allows different levels of access using a structured set of keys. It provides controlled access to various doors while enabling a single master key to unlock all designated locks within the system.
For example, in an office building:
- Employees have keys that open only their specific offices.
- Managers have keys that open multiple offices.
- The owner or security head has a Master Key that opens all doors.
This system eliminates the need for carrying multiple keys and provides a more secure and convenient solution for access control.
How Does a Master Key System Work?
A Master Key System works by using a special configuration inside the lock cylinder. The locks are designed to work with multiple keys, each granting access based on predefined levels.
Key Levels in a Master Key System
- Change Key (Sub-Key) – Opens only a specific door and is assigned to individuals with limited access.
- Master Key (MK) – Opens all locks within a specific group (e.g., all office doors in a department).
- Grand Master Key (GMK) – Opens multiple groups of locks (e.g., all office doors in different departments).
- Great Grand Master Key (GGMK) – The highest-level key, which opens all locks in the system.
Each key level is strategically assigned to allow access to specific areas while restricting unauthorized entry.
Benefits of a Master Key System
1. Enhanced Security and Access Control
With a Master Key System, you can control who has access to different areas of your property. This helps prevent unauthorized entry and ensures only trusted personnel can enter restricted zones.
2. Convenience and Fewer Keys to Carry
Instead of managing multiple keys for different doors, a Master Key System allows authorized personnel to carry just one key, significantly reducing key clutter.
3. Customizable Access Levels
Whether you need different access levels for employees, managers, and executives, a Master Key System can be tailored to suit your security needs.
4. Cost-Effective Solution
A Master Key System reduces the need for multiple locks and complex security systems, making it a budget-friendly option for businesses.
5. Quick and Easy Rekeying
If a key is lost or an employee leaves, rekeying a Master Key System is faster and more cost-effective than replacing multiple locks.
