What is a master keyed system?
A master keyed system comprises a number of cylinders/locks that allow different groups or individual key holders to gain access to all or individually defined areas of a building or buildings.
What are the benefits of a master keyed system?
There are many benefits of a master keyed system, but the overriding one is that access can be controlled across a building allowing appropriate people access to defined parts of the building.
Secondary advantages mean that individuals can have access using only a minimum number of keys.
Are there any disadvantages to a master keyed system?
With most security measures the objective is the right balance between convenience and security. A master keyed system can be both convenient and secure. However, it should be kept in mind that if a master key is lost or stolen the security of any of the locks that key activated is compromised. It is sometimes argued that when a lock accepts a large number of different keys it is conceivable that it could be more vulnerable to picking; however the number of break-ins where a cylinder is picked is extremely small. Current master key lock designs make lock picking almost impossible.
How flexible is a master keyed system?
A master keyed system is a dynamic entity. As your business/organisation changes a good and well planned master keyed system should be able to adapt to changing requirements.
Can a master keyed system be installed in phases?
Yes, this is very often the case, particularly when putting master keyed systems into existing buildings.
Ideally, the system should be planned and agreed in its entirety, possibly even allowing for future expansion and changes, and the actual cylinders can be called for over a period of time to suit budget availability.
