What is a Restricted Keyway Lock?

Restricted Keyways are lock cylinders with unique key slots designed to limit access only to authorized key holders. The key slot refers to the specific shape and configuration of the keyhole within the lock cylinder.

In a restricted keyway system, the key slot design is usually uncommon or not easily accessible, making it more difficult for unauthorized individuals to duplicate keys or gain unauthorized entry. Restricted keyways are commonly used in high-security settings where access needs to be tightly controlled, such as government buildings, corporate offices, or sensitive areas within facilities.

A key feature of restricted keyways is that they are typically protected by patents, meaning that the design of the key slot is proprietary and owned by the lock manufacturer. This helps prevent unauthorized key duplication, as only authorized locksmiths can obtain the necessary authorization from the lock manufacturer to duplicate keys.

Restricted keyways may also come with additional security features, such as specialized key blanks, unique key codes, or key control policies, to further enhance the security of the system. These measures help ensure that only authorized personnel can access restricted areas or facilities.

Restricted keyway systems are typically designed, manufactured, sold, and serviced by specialized providers or lock manufacturers. These providers often require relevant authorizations and licenses, and work in collaboration with lock manufacturers to provide specialized keys and locks to ensure the security and legality of the system.

Restricted keyway systems are commonly used in commercial and institutional settings, such as large corporations, government agencies, healthcare facilities, schools, hotels, public facilities, etc., to ensure strict control and restriction of access to specific areas or resources. These service providers typically offer a range of services, including system design, installation, maintenance, authorization management, and key control, to meet the needs and requirements of their customers and ensure the security and reliability of the system.

Is “Do Not Duplicate” really a deterrent?

In fact, in some countries or regions, having “Do Not Duplicate” engraved on keys does not have legal binding force, as it is merely a suggestion rather than a mandatory restriction. Moreover, keys with such engravings can still be duplicated, as key engraving is not a valid form of identity verification, and duplicating keys does not necessarily require the possession of an original key.

Therefore, the security of restricted keyways primarily relies on their patented or proprietary key designs and strict key control measures, rather than the presence of “Do Not Duplicate” engravings.

Restricted keyways are not absolutely secure either

The security of restricted keyways relies on strict key control measures, including limiting key duplication permissions. However, if unauthorized individuals are able to obtain the original key or duplicate the key through other means, the security of restricted keyways can be compromised.

Although restricted keyways typically use patented or proprietary keyway designs, it does not mean that they are absolutely secure. Advanced techniques such as key copying, key machining, lock picking, and other methods can still pose a threat to restricted keyways.

While restricted keyways may have physical attack features such as resistance to pulling and prying, they can still be vulnerable to violent destruction or physical attacks. For example, using excessive force or specialized tools to force open or damage the lock body may bypass the security of restricted keyways.

If you require a higher level of security protection, you may consider installing an electronic access control system. If you are interested in this option, please contact us for more information.
