Key control, not just keys
Every business hands out keys: to staff, cleaners, contractors and managers. With standard keys, each one can be copied at a shopping mall kiosk in two minutes, and you never find out. A restricted master key system closes that gap.
Each person gets a single key that opens only the doors they need. Supervisors and managers carry keys that open more, and the owner or facilities manager holds the master. The key profile is restricted, so blanks are not available to the public and copies can only be cut by us, on your written instruction.
How our restricted systems work
- Numbered key schedule. Every key is stamped with a number and recorded against the person who holds it, so you can audit your keys at any time.
- Signed authority. Only nominated people in your organisation can request a new key, in writing. Staff cannot order copies themselves.
- Keys cannot be duplicated elsewhere. The blanks are restricted to authorised dealers and cut on controlled machines.
- Designed around your building. We map who needs access to what, then build a hierarchy of grand master, master and individual keys that fits how you actually operate.
- Expandable. New doors, padlocks and cabinets can be added to the system later without starting again.
Who uses restricted master keys
We install and manage restricted systems for banks, supermarkets and retailers, offices, warehouses and property managers, schools and other sites where many people need different levels of access and a lost key can’t be allowed to become a security problem.
Key profiles we supply
We match the level of protection to the site. Profiles we work with include EVVA 4KS, OZ, Binary Plus, GP1, Primus and Series 6. For the highest security requirements we recommend EVVA 4KS, a patent protected system we supply as an authorised agent.
What the process looks like
- We visit the site, walk through every door and talk through who needs access where.
- We design the key plan and give you a fixed quote.
- Cylinders are pinned and keys are cut in our Mt Roskill workshop.
- We install the cylinders, issue numbered keys and hand over the key schedule.
- Future keys and changes are handled on your signed request.
Frequently asked questions
What is a restricted master key system?
It is a set of locks where each person gets one key that opens only the doors they need, while managers hold keys that open more. The "restricted" part means the key profile is controlled: blanks are not sold to hardware stores or key kiosks, and new keys are only cut by the authorised locksmith on the written request of a nominated signatory.
Why not just use ordinary keys?
Ordinary keys can be copied at any key cutting counter in minutes, so once a key leaves your building you have no idea how many copies exist. With a restricted system you know exactly how many keys exist, who holds each one, and nobody can get another without your authorisation.
What happens when a staff member leaves without returning a key?
Because every key is numbered and recorded, you know exactly which doors are affected. Only those cylinders need to be re-keyed, not the whole building, and the replacement keys stay under the same controls.
How much does a master key system cost?
It depends on the number of doors, the hierarchy of access and the profile you choose. A small shop might need a handful of cylinders; a supermarket or office building can run to dozens. We survey the site, design the key plan with you and give a fixed quote before any work starts.
Can padlocks and cabinets be on the same system?
Yes. Padlocks for gates, fences, containers and power boxes, as well as cabinet and cupboard locks, can be keyed into the same restricted system so staff carry fewer keys.
