Master Key Systems

What is a Master Key System?

A master key system is a key management plan whereby a master key in the system can open several locks which have their own individual keys. These master keys work with different types of lock such as door locks, cabinet locks or padlocks, as long as the cylinder inside them is of the same model. Master keying is commonly used when a key hierarchy is required to restrict the access that people have to different areas or levels of a building.

Why Should You Install a Master Key System for Your Business Premises?

If you manage a business, you understand the importance of security. You want to protect your employees, your inventory, and your customers. One way to do this is by installing a master key system. This system allows for the use of multiple keys, each of which can open some, but not all, of the locks in the system.
As a business owner, you understand the importance of security. You want to protect your employees and your commercial property.

Below are some of the benefits of installing a master key for your business:

  1. A master key system adds an extra layer of security.
  2. It’s more convenient than carrying around multiple keys.
  3. You’ll have access control and can easily track who has access to which keys and when they accessed them.
  4. You can quickly change the locks if an employee is terminated or loses a key.
  5. It can save you time and money in the long run.
  6. It can help prevent lockouts (and the associated costs).

Master keyed lock systems forms

Master keyed lock systems can take many different forms. For example, an office building leased by a company with some individual offices. Each of these offices can have its key. The master key would then have access to all of these offices and generally be held by the head of the company, management personnel, security staff, and/or the cleaner.
Then for a multi-level building, a grand master key provides access to all the doors in the building, and level master keys are created for each level which only accesses the doors on their respective level.

In other words, such as the following format:

  • Grand Master Key: Access to all doors and locks in all departments and floor level
  • Master Key: Access to a department or floor level
  • Individual Key: Access to an office in a department or floor level

What is a Restricted Key System?

Master key systems with restricted key systems helps maintain better key control with high security practices. A restricted key system is where the keys supplied are restricted in its distribution either covered by a patent, design registration or formal agreement. This makes duplication of restricted keys by unauthorised third party extremely difficult. A master keyed system has a lower number of keys, reducing key replacement costs. It is also convenient and provides quick access to all rooms, which can save lives in case of emergency.

Is Your Restricted Key Design System Expired?

If you have a restricted key design system in place for your business, it’s important to regularly check and make sure that it hasn’t expired. An expired system can leave your business vulnerable to security breaches and theft.
Here are a few things to look for to see if your system needs to be updated:
1. Check the date on your key cards. If they are more than a year old, they may no longer be valid.
2. Make sure all of your employees who have access to the restricted keys are still employed by your company. If someone has left the company, their key card should be deactivated.
3. Review your security procedures to make sure they are still up-to-date and effective. If you’ve made changes to your business since implementing the restricted key system, those changes should be reflected in your security procedures.
