Loosen the lock's tightening bolt, allowing the pin keys to slide flush against the cylinder tube.
Press the keyhole end of the lock gently against something flat, such as a wall or table.
Slide the pin inside the tube into its corresponding notch on the lock. Tighten the tightening bolt so that the pins are still able to move.
Insert the seven-pin lockpick straight into the lock. Turn it to the right slightly as you push the pick in. The pin keys move backward as you do this. Press the pick against the spring at the back of the lock.
Continue pushing in on the lockpick while turning it to the right. This causes the lock to open. Tighten the tightening bolt further so that the pins are secured in place and cannot move. Remove the lockpick.
