Restricted key systems solve a common commercial security problem: employees who need master keys during employment but could make unauthorized copies before leaving. Standard keyways can be duplicated at any hardware store without authorization. Restricted keyways prevent this by limiting key cutting to authorized dealers who verify owner identity before duplication.
The mechanical and legal restrictions work together. Mechanically, the key profile is patented so generic blanks don't exist. Legally, authorized dealers sign contracts committing to verify owner identity before cutting replacement keys.
Every duplication is logged in a manufacturer tracking database.

How restricted key control works
Restricted key control combines two layers of protection. Mechanically, the key profile is patented by the manufacturer. Blank keys can only be purchased by authorized dealers under licensing agreements.
Hardware stores cannot stock or cut these profiles because they can't obtain the blanks.
Legally, authorized dealers contractually commit to verifying owner identity before cutting replacement keys. The verification process requires owner authorization paperwork (typically a signed authorization letter on company letterhead or a key card issued at installation). Dealers log every duplication in the manufacturer's tracking database.
The result is multi-layered protection. A lost key cannot be duplicated at a hardware store (no blanks available). Even an authorized dealer won't cut a replacement without owner verification.
And the audit trail shows exactly when each key was duplicated and by whom.

Restricted key system FAQs
Common questions about commercial restricted keys.
What does 'restricted keyway' actually mean?
A key profile protected by patent and dealer licensing. Only authorized dealers can obtain blanks and cut keys. Requires owner authorization for every duplication.
Prevents unauthorized copies.
How much does a restricted key system cost?
Installation: $245-$545 per cylinder including hardware. Owner authorization setup: $95 one-time. Key duplication: $45-$65 per key through authorized dealer only.
Can lost restricted keys still be copied?
Not without owner authorization. Authorized dealers verify owner identity before cutting. This prevents lost keys from being secretly duplicated at hardware stores.
Which brand is best for our business?
Depends on budget and security needs. Schlage Primus is the easiest retrofit. Medeco M3 is the most common value choice.
Mul-T-Lock MT5+ is the maximum security option. We consult during assessment.
Can we master key a restricted system?
Yes. Master key hierarchies are supported by all major restricted keyway brands. Common for commercial installations with differential access needs.
What happens if the owner authorization is lost?
You contact us to re-register. The manufacturer has records tied to the system installation. Re-registration takes 2-5 business days but can be expedited for urgent needs.
Do we need both physical and electronic access?
Not required but often recommended. Physical restricted keys for reliability and emergency access. Electronic access control for daily convenience and audit trails.
Defense in depth.
Can you convert our existing commercial hardware to restricted?
Yes. Retrofit cylinders fit into existing Grade 1 commercial hardware. The lock body stays; only the cylinder is replaced with the restricted keyway version.
How is this different from standard Grade 1 locks?
Grade 1 is physical durability and attack resistance. Restricted keyway adds legal and mechanical key control on top. Most commercial restricted keys are also Grade 1 - you get both.
Does this help with DEA compliance for medication storage?
Yes. DEA requires substantial construction and controlled access for Schedule II-V storage. Restricted keyways meet the key control aspect of DEA requirements.
Can multiple dealers cut keys for our system?
Only authorized dealers for your specific brand. Our authorization lets us cut Medeco, Mul-T-Lock, and Primus. Other authorized dealers in your area can also service your keys if you provide the owner documentation.
What if we're audited and need to prove key control?
Documentation is the key. We provide installation records, key holder lists, and duplication logs. Restricted keyway systems have audit trails that satisfy most compliance requirements.
