We need to know how the pin tumbler locks work to understand how bumping works. The mechanism for these bolts is relatively simple. These contain the inside of the cylinder, two kinds of pins, the key, and driver pins.

When the bolt is locked, both pins occupy the same pinhole and are pushed together by a spring, stopping rotation. When these pins are aligned, separating the pins and core creates a shear line, allowing the plug to rotate inside the cylinder.

Inserting the keyhole pushes the pins to align along the shear line, aligning with the lock. This action allows the latch to rotate the core and unlock the bolt, giving access to the door. Again, it’s a mechanism that can be manipulated with little knowledge.

Explaining Bump Keys

On the other hand, a bump key works slightly differently since it’s cut with unique sharp picks and broad valleys. This device to open doors is not for aligning the pins but to impact them under force! That’s where the issue comes for us homeowners.

The bump key goes into the tumbler lock; it relies on the spring tension of the pins to align it. The lock bumpers apply the impact force, or “bump,” to force the key deep into the lock, causing the jar and the driver pins to “jump” just for a second or less. Once these are forcedly aligned, the shear line turns the core and opens the door.

Burglaries can occur with no sign of forced entry. Although we cannot determine how many of these events occur because of key bumping, we can rest assured that a significant number is attributed to it, as we now know that pin tumbler locks are vulnerable to key bumping.
