Magrath Security design and install Master Key Systems and we have our very own exclusive high security restricted section system, which is trademark protected.

Key control is an essential part in a buildings security and a master key system allows you to control the movement and accessibility of people within a building or buildings.

This can either be on an open section key or a restricted security key, which is registered to stop unauthorised duplication and can include euro cylinders, oval cylinders, rim cylinders, padlocks and cam locks.

A basic master key system is set out with locks pinned in a way where individual keys operate as any other lock would, but a master key would operate all locks within its system.

Master Key System Example
Illustration shows as example of a master key system.

Magrath Security currently holds and manages hundreds of systems for a huge range of clients, from individual homes, schools, management companies and government institutions.

Magrath Security can arrange to upgrade the security of your property by installing a security lock with a registered key to your front door.  This key is then registered to you meaning no keys can be duplicated without your knowledge or authorisation.

Magrath Security can design a system to suit your needs and budget. Our systems have unlimited variations and once installed our Master Key systems can be extended, downsized or amended, to suit your needs.
