First of all: keep calm. Think of a relaxed vacation moment to shake off stress and then do the following step by step:
1. calmly go through all the codes that come into question. And test whether the suitcase can be opened after all. If you have not yet selected a personal combination of numbers, the code is: 0-0-0.
2. remember that you have a lock slider in front of you. This means: push or slide the lock to the side.
3. check whether you are "looking the right way". Number combinations such as 8-6-9 can also be read as 6-9-8.
If none of these tips work, the lock may have been damaged during the journey. In this case, please contact the retailer where you bought the suitcase directly or report the damage to the transport company.
