You force the inner chamber to twist in the direction it would eventually go to unlock. Most locks inner core will have a tiny bit of play. You then go down the line pushing each pin up until the split gets stuck in the top, outer part. Once all pins are "out" the inner barrel will turn, lock picked.

You use a torque wrench to turn the bottom chamber slightly, then you push up on the a pin until it sets. What does it mean to set? It means the top pin gets stuck in the top chamber, resting on the bottom chamber. Rinse an drepeat until the dividing line in the middle is clear, and the lock opens. This can happen because the holes in the chamber aren't drilled in a perfectly straight line, and lockpickers take advantage of it

One way to open locks is to use a drill bit to drill right above the top of the keyway. The idea is to completely obliterate the "shear line" which is the line between the inner cylinder, called the core, and the outer part. That's why many high security locks have hardened steel pins or disks embedded at the top of the core.
