Oklahoma Locksmith Practice Exam

Which component of a lock provides resistance to picking and drilling?

1. Pins

2. Detainers

3. High-security features

4. Knobs

The correct answer is: High-security features

The component that provides the most significant resistance to picking and drilling in a lock is found in high-security features. High-security locks are designed with advanced mechanisms and materials that make them difficult to compromise. These locks may include features such as hardened steel inserts that resist drilling, complex pin configurations that thwart picking attempts, and additional security measures like electronic components or patented keyways that limit key duplication. While pins and detainers are essential mechanisms within various lock types, they do not inherently provide the same level of protection as high-security features. Pins may be part of a standard pin tumbler lock, which can still be vulnerable to skilled picking techniques. Detainers are another locking mechanism but also lack the robust protective qualities of high-security features. Knobs serve as part of the lock's exterior and do not actively contribute to the lock's resistance to picking or drilling. In summary, high-security features integrate multiple advanced elements that significantly enhance a lock's resistance to unauthorized access, making them the most effective choice for protection against picking and drilling.
