Prestolocks are guaranteed for life, and they are easy to reset. If you have a new briefcase and want to customise the combination, or if you've inherited a briefcase or bought one second-hand and aren't sure what the combination is, with a little time and persistence you can figure it out and reset the combination.

Instructions

  1. 1

    Use the current combination to open your briefcase. If your briefcase featuring a Prestolock is new, the factory setting for the combination is "0-0-0." If you do not know the current combination, test all possible number combinations until you find one that opens the briefcase.

  2. 2

    Write down the three-digit combination you are going to use as the new combination.

  3. 3

    Hold the reset button--on the inside of the briefcase, behind the combination lock--down with one finger while you rotate the numbers on the Prestolock until they are set to your new combination.

  4. 4

    Let go of the reset button. Rotate the numbers on the combination dial to scramble them.

  5. 5

    Test your new combination by entering the combination. If the briefcase unlocks, you have successfully changed the combination.

Tips and warnings

  • When you choose a combination, make it easy to remember, but not so easy that someone can guess it easily. Don't use three of the same number.
