What Is a Restricted Key System?
A restricted key system uses patented or controlled key blanks that can’t be copied at standard key cutting kiosks or hardware stores. Extra keys are only issued through an authorised locksmith (and usually only with permission from the key system owner). This gives you far better key control, especially when staff, tenants, contractors, or cleaners have access.
Why Businesses Choose Restricted Key Systems
For commercial sites, lost keys and uncontrolled duplicates are a real security risk. Restricted keys help you:
- Control who can request additional keys
- Reduce “mystery copies” made without approval
- Improve security when staff change or keys go missing
- Keep access organised across multiple doors and users
Restricted key systems are also a strong foundation if you plan to expand into a master key system later.
Restricted Keys for Homes & Rentals
Restricted key systems aren’t just for big buildings. They’re ideal for homeowners and landlords who want tighter access control, especially when:
- You’ve had trades or previous occupants with keys
- You’ve moved into a new home and want peace of mind
- You manage a rental and want to prevent tenants copying keys
- You want to issue spares without losing control of security
If security is a priority, a restricted key system is often a better long-term solution than standard key-and-lock setups.
