Understanding Master Key Systems: A Guide for Property Managers

For property managers, balancing security and convenience is a daily challenge. You need to control who can access certain areas while making sure you can get in quickly when needed. This is where a master key system becomes an invaluable tool.

What Is a Master Key System?

A master key system is a way of organising locks so that different keys open specific doors, while one “master” key can open all of them. For example, tenants might have keys that work only on their unit or office, while you, as the property manager, hold a master key that grants access everywhere.

Why Property Managers Use Them

Access control – Limit entry to only those who need it.
Fewer keys to carry – One master key instead of a bulky set.
Quick emergency access – Essential for urgent maintenance or safety checks.
Customisation – Systems can be designed for multiple layers of access.

Compliance and Security

A licensed locksmith should design master key systems to meet Australian security standards. For commercial and multi-residential properties, restricted key systems are recommended—they can’t be duplicated without your authorisation, keeping the system secure over time.
