In this blog we will be looking at master key systems; what they are, how they work, the benefits and more!
What is Master Keying?
A master key system refers to a mechanical locking system used throughout a building or complex, where one key can be used to access multiple different locks. Master key systems are designed to either provide or limit access to certain locked areas within a building.
Master key systems use cylinder locks featuring additional pins, these are referred to as either the ‘master shim’ or ‘wafer pin’. These allow the locks to be accessed by both normal individual keys, and master keys. The extra pin is inserted between the top and bottom pins within a standard cylinder lock, meaning the master keyed lock can be unlocked using at least 2 different keys.
Different Keys in Master Key Systems
As well as having master keys, there are also two other types of keys used within master key systems; Submaster keys and differ keys.
Submaster keys are designed to access certain doors, depending on the holder of the key. Master key systems work on a key distribution hierarchy, so submaster keys will have more access than keys that can only unlock one single lock, but they will not have as much access as the master key.
Differ keys are used where each lock has a unique cylinder that requires a different key to lock/unlock it. These keys will only unlock the lock they are specified for.
Benefits of Master Key Systems
There are many benefits of using a master key system, including enhanced security, control, and convenience.
Increased Security
Master key systems have the benefit of increased security. Planning a master key system means that all access is predetermined, as specific keys grant specific access. This increases the level of security for all involved, as well as the security of goods which may be stored in locked places. The decreased number of keys in a master key system also means that there are fewer keys that go missing.
Level of Control
The level of control is higher with a master key system, which is another benefit. Master key systems ensure that access at all levels is controlled. It is also not possible to get a master key, or a submaster key copied at any locksmiths. The only way you can duplicate a master key, or get a replacement, is for the registered owner to order one directly through the supplier or manufacturer.
Convenience
Having a system with a reduced number of keys means replacing lost/damaged keys is cheaper and more convenient, it also means you won’t have to carry lots of keys around together, which can get confusing and heavy.
Ordering a Master Key System
When ordering a master key system, it is important that you have planned the number of doors, number of keys, who has access, and the sizes of the cylinders. Creating a table as shown below can be very helpful when ordering a master key system.
