What Is a Restricted Keyway?
The plain-English explanation of restricted keys and why they matter.
The problem restricted keys solve
Standard keys can be duplicated at any hardware store. That means every 'trusted' contractor, ex-partner, or previous owner could still have working keys.
For most homes, that's an acceptable risk. For higher-value or higher-turnover properties, it isn't.
How it works
Restricted keyways use patented or controlled blanks. Only authorized locksmiths can duplicate them, and only for verified owners.
Every duplication is documented.
Popular restricted systems
Popular systems include Medeco, Mul-T-Lock, Assa, and various regional brands. A locksmith can match a system to your existing hardware.
Compatibility varies by brand.
Cost and tradeoffs
Restricted keys cost more per copy and require a specific locksmith to duplicate. That's a feature, not a bug.
Budget accordingly.
When it's the right choice
Restricted keyways are the right call for landlords, businesses, high-value homes, and anyone with genuine key-control concerns.
