North Carolina Locksmith Practice Exam

What feature does a Group 1R lock have compared to a standard Group 1 lock?

1. Higher manipulation resistance

2. X-Ray resistance

3. Ability to withstand less expert manipulation

4. Lower security standards

The correct answer is: X-Ray resistance

A Group 1R lock is designed to provide specific enhancements in security features compared to a standard Group 1 lock. One of the key characteristics is its increased manipulation resistance. This means that a Group 1R lock has been engineered to better withstand attempts by unauthorized individuals to manipulate the lock mechanism. The option referring to X-ray resistance is misleading because while some high-security locks may have features to resist tampering or unauthorized access via methods that could include visual inspection (not specifically X-ray), the real distinction between a Group 1 and a Group 1R lock lies more in the manipulation resistance provided by the Group 1R design. This understanding emphasizes the importance of evaluating the security measures in place within different lock classifications. The higher level of manipulation resistance found in a Group 1R lock makes it a more secure choice than a standard Group 1 lock.
