To understand how bumping works, we need to know how the pin tumbler locks work. 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 in a locked position, both pins occupy the same pinhole and are pushed together by a spring, stopping rotation. When these pins are aligned, the separation between the pins and core creates a shear line, allowing the plug to rotate inside the cylinder.

When inserting the keyhole, thus 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. It’s a basic mechanism that can be manipulated, by just a small knowledge.
