Do you lock your suitcase when you travel? If yes, then there are some things you need to be aware of if you travel to the USA for example. If the admission authorities want to inspect your luggage, they will open it whether it's locked or not and they don't ask for permission. Those are the rules.
If you have a TSA-approved lock on your suitcase, the autrorities have special keys that allow them to open and relock the locks without cutting or breaking them. Then your lock is still intact and your luggage - still safe from theives. Check out our selection of TSA-approved locks here.
