When it comes to security and access control systems, there are various options available to ensure the safety of a building or facility. Two commonly used key systems are UL347 and restricted keys. While both systems offer enhanced security features, there are some key differences between them. Let’s dive into the specifics of UL347 and restricted keys to understand their unique characteristics and advantages.
1. UL347 Keys
UL347 stands for Underwriters Laboratories Standard 347, and it is a nationally recognized certification for key security. UL347 keys are designed to provide a high level of protection against unauthorized duplication. These keys are typically used for commercial and industrial applications where strict control over key duplication is necessary.
The process of obtaining UL347 keys involves submitting the key design to Underwriters Laboratories for evaluation and testing. Once the key design is approved, the manufacturer is authorized to produce keys that meet the UL347 standard. These keys often come with unique features such as intricate keyway designs, complex bitting patterns, and special key blanks that are difficult to duplicate.
The primary advantage of UL347 keys is their level of key control. Since the key design is registered with Underwriters Laboratories, only authorized locksmiths or key control centers can duplicate these keys. This ensures that unauthorized copies cannot be made without proper authorization, enhancing the overall security of the system.
2. Restricted Keys
Restricted keys, on the other hand, are another type of high-security key system that offers increased protection against unauthorized duplication. These keys are often used in residential, commercial, and institutional settings where key control is paramount. Restricted keys differ from standard keys by incorporating added security features that prevent unauthorized key cutting.
Restricted key systems are typically proprietary, meaning they are exclusively produced by specific manufacturers or locksmiths. The key blanks used in restricted key systems are not readily available in the general market, making it more challenging for unauthorized individuals to reproduce them. These keys may also incorporate complex keyway designs, patented key blanks, and advanced manufacturing techniques to further enhance their security.
The key control measures in restricted key systems include strict control over key blanks and issuing limited authorization for key cutting. Only authorized locksmiths or distributors have access to the necessary key blanks and cutting equipment. This helps maintain a high level of security, as unauthorized copies of restricted keys cannot easily be made.
The primary advantage of restricted keys lies in their key control and protection against unauthorized duplication. Since the key blanks are not widely available, it becomes significantly more difficult for someone to make unauthorized copies. Restricted keys provide an additional layer of security and peace of mind for property owners and managers.
3. Key Differences
While both UL347 and restricted keys offer enhanced security features, there are some key differences between them.
UL347 keys undergo a standardized testing and certification process by Underwriters Laboratories, ensuring a specific level of security. On the other hand, restricted keys are often proprietary and incorporate unique security features that vary depending on the manufacturer or locksmith.
UL347 keys are generally associated with commercial and industrial applications where strict control over key duplication is required. Restricted keys, on the other hand, are used in various sectors, including residential, commercial, and institutional settings.
The key control procedures differ between the two systems. UL347 keys are typically controlled by authorized locksmiths or key control centers. Restricted keys are controlled by a specific manufacturer or locksmith, who has exclusive rights to the key blanks and cutting equipment.
Both UL347 and restricted keys offer increased security and key control. UL347 keys meet the nationally recognized standard for key security and provide strict control over key duplication. Restricted keys, on the other hand, incorporate unique security features and are produced exclusively by specific manufacturers or locksmiths. Understanding the differences between these key systems can help property owners and managers make informed decisions regarding their security needs.
