  1. Open your lock using its current combination code.
  2. Rotate one of the dials so that it no longer matches up with its corresponding hash mark.

    > Note: depending model design there may be requirements around directionality here

  6. Focusing on only one dial at time(depending on indication) set(dial) that in correct position:

a. Using no force other than the movement of the dial itself, rotate it to its desired number.

> Note: Some Locks do not have a clear click effect while others will make an audible β€œclick”  when you've reached each numerical value

b. Continue rotating the dial past your desired number and then stop at your next numeral match

>Note: The second or third rotation should cause a noticeable click sound as above.
  1. Repeat step (5) with remaining dials

  2. After making all three changes (dials set to new combination numbers), use your finger once again to press down firmly on unlocked dial(to reset adjustments made).

  3. Test out your new combination by locking and unlocking the lock several times before closing

By following these simple steps, you can easily reset your 3-digit Master Lock without having to worry about forgetting or losing access to your previous combination code.
