certified master locksmith Interview Questions and Answers

1. What is the difference between a pin tumbler lock and a wafer lock?

   • Answer: Pin tumbler locks use a series of pins that must be aligned to allow the lock to open. Wafer locks use thinner, flat pieces called wafers that, when aligned, allow the lock to turn. Pin tumbler locks are generally more secure.

2. Explain the process of picking a pin tumbler lock.

   • Answer: Lock picking involves manipulating the pins within the lock cylinder to the correct height, allowing the lock to turn. Tension is applied to the plug, while individual pins are carefully lifted to their shear line using specialized picks. Once all pins are set, the plug will rotate, opening the lock.
