Restricted key systems
Know who holds your keys, and control who can get more.
In a restricted-key arrangement, additional keys are requested and supplied through an authorised process instead of being copied wherever someone likes. NorthTech plans and installs restricted-key arrangements for Melbourne businesses and properties with many doors or users.
Planned design, installation and handover are arranged through our office, Monday to Friday, 8am–6pm, and Saturday, 8am–12pm. Urgent locksmith callouts remain available 24/7.

What we do
What a restricted-key arrangement changes.
The aim is control over who can obtain more keys, not only over which door each key opens.
Authorised key requests
Restricted-key arrangements can require an authorised process for obtaining additional keys. We explain the rules of the chosen system and keep the authorisation process clear.
Works with a master key hierarchy
A master key system decides what each key opens; a restricted-key arrangement controls how more keys are supplied. A property can use both.
Planned around people and change
Staff leave, tenancies change and new areas are added. We plan the arrangement so it stays manageable when they do.
Installed, tested and handed over
After installation, the key groups are tested and the people responsible are shown how the arrangement works and how to request changes.
A considered approach
Is a restricted-key arrangement right for you?
It suits premises where keys matter: workplaces with many staff, buildings with several tenancies and properties where keys need to stay accounted for. For a single door, rekeying may be all you need.
The right choice depends on the doors, the people and how often access changes. We inspect the existing hardware first and explain what can be kept, what should change and how additional keys would be requested.
NorthTech is a Series Six dealer. This Australian Lock Company system is one option for medium-security master key arrangements with controlled replacement keys. We assess whether it suits your property before recommending it.
Common questions
- What is a restricted key system?
- It is a key arrangement in which additional keys are requested and supplied through an authorised process, so extra copies are not made freely. The details depend on the system chosen for the property.
- Are restricted keys the same as master keys?
- No. They answer different questions: a master key decides what a key can open, while a restricted-key arrangement controls how additional keys are requested and supplied. Many properties use both.
- Can an existing building be converted?
- Often. It depends on the existing locks and doors and on the access you need, so we inspect the hardware before saying what can stay and what should change.
- How do I get an extra key?
- Additional keys are requested through the authorised process agreed when the system is set up. NorthTech is a Series Six dealer. Keys are cut on site, at your property; we do not offer office key cutting. Ask us how it would work for your premises.
