When picking a padlock, the only part you need to worry about is the part where the key goes into the lock. The locking mechanism has pins attached to springs. The key pins are on the bottom and the driver pins are on the top. The key turns when the pins of different heights are separated, flush and aligned. Stick a tension wrench into the keyway and put pressure on it. Take a pick to push the rest of the pins up until they are flush with the shear line. Stick the tension wrench into the bott...
