Why Upgrading to a Patent-Protected System Is Critical for Schools, Hospitals & Government Buildings
Can you account for every restricted key in your building?
Across Australia, more than 80% of restricted key systems currently in use are outdated or no longer legally protected. Many organisations believe their keys are “restricted” — but the patent or registered design protection expired years ago.
If your premises rely on an outdated master key system, your security may already be compromised.
What Is a Registered Key System?
A registered key system is a high-security locking system where:
- The key profile is legally protected
- Only authorised locksmiths can duplicate keys
- Key cutting requires signed approval
- Strict key control procedures are enforced
This prevents unauthorised key duplication and protects your building from uncontrolled access.
As outlined in the Registered Key Expiry notice
- Patent Protection provides legal protection for up to 20 years.
- Registered Design Protection protects key profiles for up to 10 years.
- Once expired, any manufacturer may legally reproduce that key design.
That means former “restricted” keys may no longer be restricted at all.
The Hidden Risk: Expired Registered Key Systems
Many commercial and government facilities are still operating on:
- Expired Lockwood profiles
- Legacy Abloy systems
- Older master locksmith keying systems
- Restricted profiles no longer legally protected
When patent or registered design protection expires:
- Keys can potentially be copied
- Your building loses controlled access integrity
- Master key hierarchies become vulnerable
- Security compliance may be compromised
For schools, hospitals, and government buildings — this is not just inconvenient. It is a serious security liability.
Why Restricted Master Key Systems Are Essential
A restricted master key system allows controlled, tiered access across:
- Classrooms and staff rooms (schools)
- Wards and medication storage (hospitals)
- Sensitive government offices
- Commercial multi-site operations
- Industrial facilities and warehouses
Benefits include:
✔ Controlled key duplication ✔ Centralised key management ✔ Reduced rekeying costs ✔ Hierarchical access control ✔ Enhanced security compliance ✔ Audit trail capability
Without a legally protected registered system, these benefits weaken significantly.

Why Security Edge Is Different
Key Security with an Edge
Security Edge combines:
- 6-pin inline keying system
- Sidebar wave configuration
- Unique side-cut key profile
- Individually designed sidebar patterns
When inserted, the key aligns with a uniquely etched sidebar inside the cylinder, allowing rotation only when the correct pattern matches.
This provides strong resistance against:
- Picking
- Bumping
- Drilling
- Impressioning
- Plug torque attacks
Independently Tested & Accredited
Security Edge cylinders are:
- Independently tested by NATA
- Accredited to AS 4145.2 standards
- Tested for over 114,000 durability cycles
- Rated for resistance to picking, bumping, drilling & plug torque
This makes Security Edge one of the most robust high security restricted key systems in Australia.
Ideal for:
Schools
Control access to:
- Classrooms
- Administration areas
- Staff-only spaces
- Restricted storage areas
A properly designed master key system prevents uncontrolled duplication and protects students and staff.
Hospitals & Healthcare Facilities
Secure:
- Medication rooms
- Records rooms
- Staff-only areas
- Controlled access wards
In healthcare environments, key control is critical for safety and compliance.
Government Buildings
Protect:
- Sensitive documentation

Outdated key systems expose agencies to unnecessary risk.
Commercial & Industrial Sites
From a single building to multi-site operations, Security Edge systems are scalable and flexible, making them ideal for:
- Corporate offices
- Warehouses
- Construction sites (with construction keying options)
- Retail operations
Construction Keying Advantage
Security Edge is the only high security product available on the Australian market designed with construction keying options — allowing temporary access during building works while maintaining long-term master key integrity.
More Than 80% of Systems Are Outdated
Industry experience shows that the majority of existing master key systems installed before 2015:
- Have expired registered design protection
- Use profiles no longer legally restricted
- Rely on outdated cylinder technology
If you cannot confirm your key system protection status, it may already be vulnerable.

🔒 Legal key duplication control
🔒 Long-term protection (Security Edge protected until 2034)

Final Thought
If your restricted key system was installed over 10 years ago, there is a high likelihood it is no longer legally protected.
Now is the time to upgrade to a registered design, patent-protected restricted master key system.
Because when it comes to protecting your premises — whether it’s a school, hospital, government building, or industrial site — security should never expire.
