Combination lock does secure the luggage but it brings a new problem - what to do if you forget the codes of the clocks?
Bear some easy tips in mind on resetting combination lock codes:
1) Try the factory codes set by manufacturers. They are usually vey simple, like 0-0-0, or 1-1-1. If this doesn't work, try step 2.
2) Get a pin and put its end into the reset button on the combination lock. This button is usually located on the side of the lock.
3) Press this button constantly while resetting the codes. Dial up to the numbers you want on the lock. Keep pushing the reset button during this process.
4) Make sure the new codes are easy to remember. But don't use any repeating numbers like 2-2-2 or sequential ones like 1-2-3.
