Master Key Systems

Master Key Systems for Controlled Access

A master key system lets you open multiple locks with one key while issuing restricted keys that open only the doors staff or tenants need. This is perfect for offices, medical suites, schools, and multi residential properties around Malvern, Caulfield, and Glen Iris.

How a master key system works

Each lock cylinder is pinned to a hierarchy. At the top is your master key, which opens every designated door. Below that, we create groups such as front entry only, storage only, or tenancy specific access. This reduces key rings, speeds up maintenance, and improves security oversight.

Benefits for property managers and owners

  • One key convenience for owners or facility managers
  • Restricted key control to prevent unauthorised copies
  • Scalable design so you can add doors or levels later
  • Clear hierarchy that matches your operational needs

We document your system and maintain authorisations for new key requests. For sites across Malvern East, Armadale, and Toorak, we can align access groups with teams, tenants, or contractor roles.

Our process

  1. Consultation to map doors, users, and security goals
  2. System design with future growth in mind
  3. Lock supply, fitment, and key issue under written authority
  4. Ongoing support for expansions and replacements

Where existing hardware is good quality, we can often adapt it to the new hierarchy and save on replacement costs.
