Instructions

  1. 1

    Rotate all the dials on the lock several times.

  2. 2

    Turn the first dial, the dial closest to the left side, until the first letter or number in the combination aligns with the mark on the side of the lock.

  3. 3

    Turn the second dial to the second letter or number in the combination, so that it aligns with the digit you selected in the previous step.

  4. 4

    Turn the third dial to the third digit in the combination.

  5. 5

    Turn the fourth dial, the dial closest to the right or on the bottom, to the fourth digit. You should now have a straight line of four letters or numbers.

  6. 6

    Pull out the lock's shackle.
