Our experienced technicians can assist you in designing, developing and maintaining a secure master keying system to ensure that your facility is solidly protected.

Keying systems range in levels of security; from standard key profile systems to highly restricted systems requiring authorisation for obtaining additional keys.

Procuring a restricted keying system from John Barnes gives you the security of knowing that your keys cannot be duplicated by anyone, and keys can only be issued by us upon stringent authorisation.

Key control is the primary aspect of your security solutions. If you can’t control who can copy your keys, you can’t control your security.

John Barnes' vast experience and expertise in the industry allows us to provide recommended high-security keying systems tailor-made to suit all your requirements.
