Master key systems have become increasingly popular for businesses as a convenient and efficient way to manage access to commercial properties. In this article, we will explore the benefits and functionality of master key systems.
What is a Master Key System?
A master key system is a system that allows for the creation of multiple levels of access to different areas of a building or property. A master key system uses a hierarchy of keys to control access to different locks. The hierarchy typically includes a grand master key, which can open all locks in the system, sub-master keys that can open a group of locks, and change keys that can only open one specific lock.
There are different types of master key systems available, including:
- Simple Master Key System: A basic system that provides different levels of access to different areas of the property.
- Maison Keying System: A system that uses a sub-master key for each floor of a building or each individual unit in a multi-tenant building.
- Grand Master Key System: A system that allows for access to all locks in the system, including sub-master and change keys.
Benefits of Using a Master Key System
One of the main benefits of using a master key system is the convenience it provides for businesses. Rather than carrying around a large set of keys, employees can carry one key that provides access to all areas they need to access.
In addition, a master key system enhances security by allowing businesses to control access to different areas of a building or property. For example, a retail store may want to restrict access to their stockroom or office, and a master key system would allow them to do so.

Factors to Consider When Choosing a Master Key System
When selecting a master key system, businesses should consider the size of their property, the number of doors that need to be secured, and the level of security required. For example, a small retail store may only need a simple master key system, while a large office building may require a grand master key system. Additionally, different industries may have specific security requirements, such as healthcare facilities or government buildings.

Implementing a master key system involves selecting the right locks and keys, creating a key hierarchy, and managing access permissions. It is important to work with a professional locksmith like Ace Locksmith to ensure that the system is properly installed and maintained.
