Cylinder Types

Varying degrees of complexity can be achieved to suit a variety of needs but there is often confusion between the different types of cylinders.

Keyed Alike:

A keyed alike system is when all locks can be operated using the same key.

Master Suites:

In a straight master keyed suite all the locks can operate off different keys, but another key (called the master key) will open them all. Keyed Alike groups can also be incorporated into any Master Key suite.

ARRONE Cylinder Master Suites

Grand Master Key Suites:

Grand Master Key suites are used when it is necessary to have more than one master key group. These groups are referred to as sub suites. In these instances, all cylinders irrespective of their sub suite, are controlled by one key known as the Grand Master Key.

Common Cylinders:

The common entrance suite removes the need to hold two keys, for example one for the front door and one for an individual room in student accommodation or a block of flats. A common entrance key will open both the front door and the individual room.
