How do pick guns operate to manipulate a lock?

1. Rotating the lock cylinder

2. Bouncing the top pins above the shear line

3. Applying pressure to the side cylinders

4. Vibrating the internal components

The correct answer is: Bouncing the top pins above the shear line

Pick guns operate by utilizing a mechanism that specifically targets the pins within a lock. The correct method of operation involves rapidly bouncing the top pins above the shear line, which is the crucial point where the pins must align to allow the lock to turn. When a pick gun is engaged, it delivers quick, controlled strikes that cause the top pins to momentarily jump above the shear line while the bottom pins remain in place. This action effectively creates a temporary unlocking condition, enabling the lock cylinder to turn and open the lock. This technique is particularly effective because most pin tumbler locks are designed to secure when the pins are aligned precisely at the shear line. By using rapid movements to manipulate the pins, the pick gun mimics the action of manual lock picking but automates the process, making it quicker and less reliant on the skill level of the operator.
