Benefits of Master and Restricted Key System

We recommend restricted key system installation for the following reasons:

  • Higher security. Lock cylinders are designed and made hardened materials and have high security technology at hat make them hard to pick or drill. Higher security locks like Kaba cylinders are virtually impossible to pick.
  • Key authorisation. When a key system is managed by Diamond Locksmiths, only authorised personal can authorise key duplications. We can cut from the key code with the submission of a key order form and do not require a key to duplicate. We will call you when it’s ready for collection or delivery.
  • Key, door and access management. If your facility has multiple locations, doors, keys and user roles, then a key hierarchy can be designed and implemented where a master key opens all doors, with lower level (change) keys only open role specific doors. The provides a cost-effective access control for various employees within your business and options for expansion as your business grows.
  • Systems information and data management: At Diamond we maintain the latest versions of ProMaster and work with you to maintain relevant and reliable system information.
  • Patented Locks and keyways. No other locksmiths or person can duplicate your keys.
