What are the Pro’s of a Restricted Master Key System?


Staff generally only need one key to enter through a gate, office door, warehouse, padlock as an example

Key control:

As a restricted key has a legal patent on it extra keys cannot be cut by anyone. Keys can only be cut through the initial locksmith who created the system and only with written documentation by the signature holder (ie; manager, business owner)

This also means that there is no need to worry of unauthorised access to you premises if you have a staff turn over once their key has been returned as they did not have authority to get keys duplicated.

Higher Security:

Restricted Key System are resistant to forms of manipulation such as; picking, drilling, bumping and hard blows.


As Restricted key systems require precision to work efficiently they are made with higher grade materials to ensure that your locks & key will last in high traffic areas.
