Restricted Master Key Systems
Restricted Master Key Systems in Perth
Service Overview
Restricted Master Key Systems are a proven security solution for commercial properties that need controlled access without the complexity of carrying multiple keys. This system uses a structured hierarchy of locks and keys, allowing different levels of access throughout a building while maintaining strict control over who can enter specific areas.
At Lock Smith Perth 247, we design and install restricted master key systems tailored to your premises, staff structure, and operational needs. These systems use restricted, patent-protected keyways that prevent unauthorised key cutting, helping protect your business from internal and external security risks.
Restricted master key systems are commonly used in offices, warehouses, medical centres, schools, strata buildings, retail sites, and government facilities across Perth.
Types of Restricted Master Key Services Offered
New Master Key System Design & Installation
We assess your site layout, access requirements, and operational structure before designing a system that balances security and convenience. Locks and cylinders are supplied and installed to suit commercial-grade use.
Restricted Key Systems
Keys are issued under strict control, with duplication only available through authorised channels. This ensures long-term security and accountability.
System Expansion & Re-Keying
As your business grows or changes, your master key system can be expanded to include new doors, areas, or access levels without replacing the entire system.
Audits & Upgrades
If you already have a master key system in place, we can audit its effectiveness, identify weaknesses, and upgrade it to a restricted keyway if required.
How Restricted Master Key Systems Work
A restricted master key system is built around a clear access hierarchy.
Individual locks are keyed so that:
Each staff member has a key that opens only the doors they are authorised to access
Department or area managers can access multiple doors within their zone
A master key can open all doors within the system
All locks are matched to a restricted key profile, meaning keys cannot be duplicated without formal authorisation. This prevents uncontrolled key copying and reduces the risk of lost or unauthorised keys compromising your site.
The system is designed during the planning stage, ensuring flexibility for future changes such as staff turnover, office expansions, or access level adjustments.
Benefits of a Restricted Master Key System
Clear control over who can access specific areas
Reduced number of keys carried by staff and management
Prevention of unauthorised key copying
Improved security through restricted keyways
Scalable design that adapts to business growth
Better accountability when keys are issued or returned
This approach improves day-to-day efficiency while strengthening overall site security.
