Pull the body of the lock and the U-shaped ring away from each other to put pressure on the mechanism inside the lock. Pull the body of the lock away from its attachment, or, if the lock is not attached, apply pressure on the U-shaped ring away from the body of the lock with your fingers. Keep holding a firm, steady pressure.
Step 2
Roll the dial closest to the U-shaped ring slowly, while keeping steady pressure on the mechanism. The dial will get difficult to roll over three consecutive numbers, and one of those numbers will click. You should feel and hear this small click, and that is the first number to your combination.
Step 3
Repeat Step 2 with the middle dial, and then the farthest dial. Leave the dial set when you find the click, moving onto the next dial. The combination will reveal itself, letting you pull the U-ring away from the body of the lock.
