Restricted keyway locks are specialized systems engineered to prevent unauthorized duplication. Unlike standard keys that can be copied almost anywhere, restricted keys are patented and may only be duplicated by authorized locksmiths or dealers. These professionals must follow strict verification steps, including confirming your identity and authorization before making a copy. This added control ensures that only approved individuals can replicate your keys, giving you enhanced security and confidence over who can access your home or business.

Restricted keyways use uniquely patented key designs that can only be duplicated by authorized dealers. To obtain an additional key, you must provide proper identification and proof of authorization at a certified dealer, who is also required to keep detailed records of every key copied. Since these keys cannot be reproduced at standard hardware or key-cutting shops, you always know who holds access. This system prevents unauthorized duplication and entry, making it an excellent choice for homeowners, businesses, and property managers looking to strengthen security.

While restricted keyways are an important component of high-security locks, they are not the same as a full high-security system. Restricted keyways focus on controlling key duplication, ensuring keys cannot be copied without authorization. High-security locks go further, combining key control with enhanced physical protection against picking, drilling, and forced entry. These locks often meet or exceed standards such as ANSI or UL ratings and are engineered to withstand aggressive attacks, making them ideal for high-risk or high-value settings. In short, restricted keyways contribute to security, but true high-security locks pair key control with robust physical defenses.
