One key. Every door.

Master keying for homes and businesses — one key that opens everything, and sub-keys that open only what you choose.

Carrying a bunch of keys for one building is a solvable problem. A master key system lets one key operate every lock in your home or business, while individual sub-keys open only the doors you decide — the office but not the storeroom, the flat but not the meter cupboard.

We design and pin master key systems to suit how your property actually runs: landlords with multiple units, offices with staff access levels, or simply a home where you're sick of the keyring. We'll map it out with you, then build it with a multitude of keying options.

Perfect for

  • Homes — one key for front, back, garage and shed
  • Small business — owner master, staff sub-keys
  • Landlords — one master across every unit
  • Body corporate and shared buildings
  • Offices with tiered access levels

Common questions

Good to know

Can sub-keys be limited to certain doors?

That's the whole point — each sub-key opens exactly the doors you nominate, while your master opens everything. We design the hierarchy with you before any pinning happens.

Can you master-key my existing locks?

Usually yes, if the cylinders are compatible — which keeps the cost down. Where they're not, we'll quote compatible hardware upfront.
