Restricted Key Systems
From single-door access to complex multi-site facilities across Perth, Gronbek designs and installs precision-engineered locking solutions tailored to your organisation’s security needs.
What is a Master Key System?
A master key system is a specially designed lock system that allows one key – the master key – to open multiple locks, even though each lock also has its own unique key. It’s a smart and secure way to manage access across a commercial property or residential building without needing a separate key for every door.
At the core of a master key system is a clever locking mechanism that uses additional pins (called master pins) inside the lock. These pins create multiple shear lines, which allow more than one key to operate the same lock. That means individual users can still have their own keys, but a master keyholder – such as a property manager or security staff – can access all designated areas with a single key.
Master key systems are ideal for both commercial and residential settings. They help streamline access control, reduce the number of keys in circulation, and enhance security. Whether you’re managing an office, apartment complex, school, or multi-unit property, a master key system offers convenience, flexibility, and peace of mind.
Rethink your Security
Gronbek: Securing what matters most!
Bi-Lock, Abloy and EVVA – Perth's Restricted Key Specialists
Not all master key systems offer the same level of key control. The brand behind your locks matters – particularly for restricted key systems where preventing unauthorised duplication is the whole point.
As authorised suppliers and installers in Perth, we work with three of the most trusted names in high-security keying.
Bi-Lock Exclusive
Developed in Australia and one of the country's most widely adopted restricted key systems for commercial properties. The Bi-Lock Exclusive system uses a patented key profile that can only be cut by authorised Bi-Lock locksmiths.
Once your system is registered, duplicate keys can't be made at a hardware store or by an unlicensed locksmith – giving you genuine control over who holds a working key. It's a practical, cost-effective choice for offices, strata buildings, and multi-tenancy sites across Perth.
Abloy Protec
The global benchmark for high-security mechanical locking. Unlike conventional pin tumbler locks, Abloy uses a rotating disc detainer mechanism with no springs, making it highly resistant to picking, drilling, and manipulation.
Abloy restricted key systems are the preferred choice for government facilities, high-value commercial premises, and any environment where security cannot be compromised. As an Abloy locksmith in Perth, Gronbek handles supply, installation, and ongoing key management for Abloy Australia systems.
EVVA
An Austrian-engineered restricted key system known for its precision tolerances and innovative key profiles. EVVA keys in Perth are suited to commercial master key environments where long-term key management and duplication control are priorities.

Who Needs a Master Key System?
Master key systems are a smart choice for any property that requires controlled access across multiple rooms, units, or departments. They're especially useful in environments where security, convenience, and efficiency are a priority.
- Office Buildings – Manage access to private offices, meeting rooms, storage areas, and shared spaces with a streamlined key system for employees, managers, and maintenance teams.
- Apartment Complexes – Keep resident access organised across foyers, garages, lifts, storage areas, and shared amenities, with controlled key handling for strata managers, maintenance teams, and approved contractors.
- Schools & Universities – Improve campus security by controlling keys across classrooms, labs, staff areas, and secure storage, with clear oversight for administration, facilities teams, and authorised providers.
- Hospitals & Healthcare Facilities – Protect patients and sensitive areas by controlling access to wards, theatres, treatment rooms, and secure storage, with accountable key management for clinical and facilities teams.
- Warehouses & Industrial Sites – Reduce downtime and protect restricted zones by managing keys for loading bays, equipment rooms, cages, and plant areas, with fast access for supervisors and maintenance teams.
- Hotels & Hospitality – Keep daily operations moving by managing keys for guest rooms, staff-only zones, storage areas, and service corridors, with smooth handovers for housekeeping and maintenance teams.
Rekeying and Changing Locks in Perth
A master key system is only as effective as the key control behind it. When a staff member leaves, a tenant moves on, or a key goes missing, you have two options – and knowing which one to choose saves time and money.
Rekeying locks in Perth means modifying the internal pins of your existing lock cylinders so that old keys no longer work, without replacing the hardware itself. It's quicker and more affordable than a full lock change, and the right call when your existing hardware is in good condition.
Changing locks in Perth makes more sense when the hardware is worn or damaged, you're upgrading to a higher security grade, or you're moving to a restricted key system like Bi-Lock or Abloy that requires new cylinders.
As master locksmiths in Perth with over 45 years of experience, our team can assess on-site whether rekeying or replacing is the better option – and complete the work the same day in most cases.
