How to Open Cylinder Combination Locks

A standard four number cylinder combination lock has more than 12,000 different locking combinations. The lock has four separate numbered barrels that range from one to eight and mount on the lock cylinder. When you select the correct combination of numbers, you can pull the notched pin out of the cylinder. The process on how to open the cylinder combination lock is straightforward.
