Master Key Systems

Strengthen Your Security With Our Master Key Systems

Key control is the most important aspect of your security. If you can’t control who can copy your keys, you can’t control your security. Our Master Key Systems gives you the power to allow or restrict access to certain areas of the workplace. You may be wondering though: How does a master key system work?

A Master Key System consists of two or more different keys to open one lock. The Master Key can operate all locks within a facility while each lock maintains its own individual key.

For example: keys issued for Office 1 won’t open the door to Office 2, but a Master Key will operate both doors. This system is convenient if an employee or tenant loses their keys or requires emergency access.
