Master Key & Restricted Key SystemsRichmond & inner Melbourne
One key for you, limited keys for everyone else — and no unauthorised copies, ever.
What master key systems actually involves
A master key system gives each holder access to exactly what they need and gives you a single key that opens everything. A restricted system adds the part most businesses actually need: the key blank is patented, so copies can only be cut by us, only for a person on your authorised signatory list. Together they stop the slow leak of keys that every organisation suffers.

Master Key Systems — what customers say
Illustrative examples — real reviews replace these at launch.
“We had eleven different keys for nine doors and no idea who held what. Now one key for me and a limited key per person.”
“Designed it so we can add the second floor later without recutting everything. Worth the extra thought at the start.”
“The restricted blanks are the part that actually solved it. Nobody can quietly cut a copy at a kiosk any more.”

Master Key Systems — common questions
How is this different from just keying everything alike?
Key alike gives everyone the same access. A master system gives each person a key that opens only their doors, while your master opens all of them. That difference is the whole point once you have more than a couple of staff.
What stops a staff member cutting a copy at the shops?
The restricted blank. It is patented and not sold to general key cutters, so a copy can only be made by us and only for someone on your signatory list. That is the control a standard key cannot give you.
Can we start small and grow it?
Yes, and you should. A system designed with expansion in mind lets you add doors, floors or a second site later without recutting everything. Designing it properly at the start is the difference.
