Master key systems are beneficial for both residential and commercial security, but what exactly is a master key system, and how can it keep your family or business safe?

In a nutshell, a master key system works like most key systems, with the exception that it allows for varying levels of access to each lock. For example, a landlord might use a master key that allows easy access to every apartment in his or her building, or you might have Cheap Lock & Key install the system for a business that requires restricted access for its employees. Whatever your use case, there are many types of keys used in a master key system to become familiar with. Let’s take a look.

  • Change Key: Also known as a sub-master key, the Change Key is the lowest level of the master key system and can only operate one lock.
  • Master Key: This is probably what your landlord or “super” has. It’s a key that opens many locks, each of which has its own key.
  • Grand Master Key: This key is designed to fit several master key system locks.
  • Great Grand Master Key: This key is at the top of the key-system chain. It allows for the greatest access and will open all subsequent key systems under it, like the ones already mentioned in this article.
