Master Key Systems

Make premises more secure and building management more efficient 

What is a master key system?

In a master key system, every key can unlock one or several openings. Each key’s reach is determined by their position in a carefully designed hierarchy.

Keys may be issued according to authority or function. For example, the CEO and security manager hold a master key which unlocks everything. IT staff keys unlock the server room and its contents, but no other offices or services. Cleaners can unlock every room, but cannot access cupboards, machines or letterboxes.

When properly configured, a master key system is secure, flexible, scalable, convenient and cost-effective.

A master key system helps you manage and filter access to multiple openings without software or wiring. Everyone opens the doors they need without carrying multiple keys. Only those with authorization get in.

Because a single key may operate multiple locks, effective master key system design reduces the number of keys you need to cut, track and replace at your organization. It saves you time and money.

A master key system frees building users from bulky keyrings and saves them time hunting for the right key. Users enjoy the convenience of carrying one key to unlock doors, lockers, letterboxes, padlocks, cabinets and more.

And with fewer keys in circulation, the problem of lost and stolen keys is reduced.
