What Is a Restricted Key System?

A restricted key system uses specially designed keys that cannot be duplicated without your authorization. These keys work with lock cylinders that only professional locksmiths can access and rekey—and only with your permission.

Key blanks are protected by patents and not available at hardware stores, kiosks, or online.

How Is It Different from a Standard Key?

Standard house keys (like Kwikset or Schlage) can be duplicated almost anywhere—hardware stores, kiosks, even mobile apps.

With restricted keys:

• Duplication is legally restricted
• Only the locksmith who installed your system can make copies
• You may be required to show ID or a signed authorization to request new keys

This gives you control over every key made—and confidence that no unauthorized copies exist.

Who Should Consider a Restricted Key System?

You might want a restricted key setup if you:

• Have housekeepers, pet sitters, or contractors coming and going
• Rent out part of your home or use it as an Airbnb
• Have had past issues with lost or copied keys
• Want maximum control over your home’s entry points
• Have teens, roommates, or caregivers with access
• Own a high-value or custom property in areas like Arcadia, Biltmore, or Camelback

It’s also a great fit for busy families who need to keep track of who has access without constantly rekeying locks.

Can You Combine Restricted Keys with Other Security Features?

Absolutely. Restricted keyways can be:

• Used with high-security deadbolts
• Added to smart locks with backup keys
• Integrated into a master key system for larger homes
• Rekeyed periodically as needed for enhanced protection

We can walk you through all options to make sure your home security is both convenient and secure.

As many as you need—but only you (or someone you authorize in writing) can request copies. We keep your key code on file and provide professional duplication only after verifying your identity.
