Restricted key systems

Restricted master key systems for your home and business — a security key that can't be duplicated without your written authority.

A standard house key or building key can often be copied in minutes, which means every key you've handed out may still be in circulation. If you need greater control over who can have a copy and further physical security of the lock itself then a restricted key system provides a more secure solution.

Restricted security keys or registered keys use protected key blanks that can only be duplicated through your authorised locksmith, with your approval. Copies can be controlled and recorded, giving you a clear understanding of who has access to your property and how many keys have been produced.

For homes, rentals, offices, commercial sites and government facilities, restricted keying gives you control over your keys rather than relying on the assumption that copies haven't been made.

Restricted master key systems take this a step further. You can have a master key for the entire property, with restricted sub-keys issued to specific people or areas. Every additional key is authorised and accounted for, so you stay in control of who has access.

Why restricted

  • Keys cannot be copied without your authority
  • A register of every key on issue
  • An extra level of security for home or business
  • Ideal for staff, cleaners, contractors and tenants
  • Combine with master keying for full control

Common questions

Good to know

How is this different from 'do not copy' stamped keys?

A stamp is a suggestion — restricted profiles are a legal and mechanical control. The blank itself is protected, so a kiosk simply can't cut one.

What happens if I need more keys?

You authorise them, we cut them, the register gets updated. That's the system working exactly as intended.
