Luggage manufacturer Samsonite offers a variety of business, personal, travel products and accessories. Many Samsonite pieces such as attaches and other bags include a three-digit, built-in combination lock. When purchased, the locks are set on a factory default combination that you can change as often as you wish.

Turn the number dials to the previously set combination, or to "0-0-0", the factory default combination for Samsonite luggage.

Locate the reset button, usually placed to the side of the combination dials.

Press the reset button and hold it while rotating the number dials to the desired combination. Set this to a sequence easy for you to remember but hard for others to figure out.

Release the reset button after you set the numbers to the new combination.

Test the combination by turning the dials to the new code to open the lock. If the combination does not open the lock, repeat Steps 1 through 4 and test the lock again. If you still can't open the lock, contact Samsonite Customer Service at 800-765-2247.
