Master key systems use mechanical locks arranged in a hierarchy —
cost-effective, reliable, no power dependency. Ideal for strata buildings, offices, and
smaller businesses.
- Grand master key — opens every lock in the system (strata
manager or building owner)
- Sub-master keys — access a section (a floor, wing, or common
areas)
- Change keys — open only the specific door assigned (tenant
or staff member)
Electronic access control adds digital
management — keycard, fob, PIN, or biometric. You can grant, restrict, or revoke
access remotely and see a full audit trail of who accessed what and when.
Commercial lock projects begin with a site assessment — the locksmith maps all
access points, identifies security levels, and designs the system before any hardware is
ordered:
- Site assessment — all doors, access levels, and key holders
are mapped to design the correct system architecture
- Hardware supply & installation — high-security cylinders,
electronic readers, control panels, and exit devices are fitted and wired
- Restricted key system — for master key systems, restricted
blanks prevent unauthorised duplication; the locksmith's name is stamped on each key
and only they can cut new ones

Master key systems are the standard solution for Central Coast strata schemes —
they give the strata manager universal access while ensuring each tenant's apartment is
secure and independently keyed.
Restricted key systems are a must for
strata: tenants can't get copies cut at a hardware store. All new keys must go through
the registered locksmith, giving you full control over who holds a key to the building
at all times.
