Master key systems
Benefits of Restricted key systems
A restricted master key system is a type of keying system used in buildings and facilities to enhance security and control over access. It typically includes master keys (which open multiple locks) and restricted keyways, which are patented or controlled profiles that prevent unauthorized duplication. Here are the main benefits:
Key duplication control: Keys cannot be easily copied at a regular hardware store; duplication usually requires authorization and must go through the locksmith.
Restricted keyways: Unique and patented designs prevent the use of blank keys readily available on the market.
Controlled Access
Hierarchical access levels: Allows different users access to only the areas they need, while a master key can open all relevant locks.
️
Fewer keys to manage: One master key can replace multiple individual keys, reducing the bulk and complexity of key management.
Simplified lock changes: If one key is lost, only specific cylinders may need rekeying, not the entire system.
Legal and Policy Compliance
Patent protection: Many restricted key systems are covered under patent law, providing legal backing to restrict unauthorized duplication.
