How does a key lock work?

Contents
Basic pin-and-tumbler locks have several spring-loaded pins inside a series of small cylinders. When the right key slides into a pin-and-tumbler lock, the pointed teeth and notches on the blade of the key allow the spring-loaded pins to move up and down until they line up with a track called the shear line.
