Restricted Keying Systems

Example of a master key system hierarchy

Restricted keying provides a much greater level of security with keys that are protected by a legal patent or a distributor agreement and can only be issued by an authorised and licensed locksmith.

This can increase the security of your home or business and provides greater key control as no keys are issued or copied without authorisation from you or your nominated signatories.

Restricted keys are generally constructed from high quality nickel silver providing greater strength and durability than standard brass keys.

Pinkerton Locksmiths record all information regarding your restricted key system so you can be sure how many keys have been issued.
