Restricted Master Key Systems

Create your own unique master keys and control who can use them

Restricted Master Key Systems

Restricted keys enable a business to keep track of who is holding keys

Restricted keys are ordered by nominated staff members and are individually numbered to allow a business to keep track of who they are issued to.

AJAX can design your unique system to suit your needs. We survey each door on site, then enter all details into our master keying software.

Our highest level of security is KABA EXPERT. Our mid level of security is DC1B which is endorsed by the MLAA.


Before we install a system, we create your own unique master key schedule, by surveying every door, then discussing with you exactly how you want it to work. Of course a copy is supplied to you to keep track of the system.

User Friendly

All our lock cylinders are stamped with door numbers, and all keys are clearly stamped for easy identification, or cross reference I.D.


It makes absolutely no difference to us (or the price) how many levels of keys you wish to have. Our prices include the supply, keying and installation of all, regardless of complexity.

Loss Prevention

No key shall be cut without the appropriate signature appearing on a basic letterhead document (preferably emailed). See our Restricted Master Key form on this page. You can choose to have your Restricted Keys either hand delivered, posted or collected from our showroom.
