A restricted system ties every key to a patented profile and an authorised holder list. Copies can only be issued to named people, which is what makes key control real rather than a policy on paper.
What's included
- Restricted cylinder supply and installation
- Master and grand master hierarchies
- Authorised signatory setup and key register
- Additional keys issued against written authority
- Expansion of an existing system as you add doors
How the job runs
- 1
Scope
Doors, users and access levels mapped before any hardware is ordered.
- 2
Design
A key chart showing exactly which key opens which door.
- 3
Install
Cylinders fitted, keys issued and signed for.
- 4
Ongoing control
Future keys only released to your nominated signatories.
Things worth knowing
- Restricted systems carry a higher upfront cost than standard cylinders. They pay off where staff or tenants change.
