What should I do if the password lock fails after the customs lock of the suitcase is used?

Let's see what the fault is. I've met many times before. The travel password lock can't be opened with the correct password, because it is caused by bumping or vibration. Try the numbers near the correct password, and you can basically solve it. For example, the default password is 000, that is, 00 1, 002,003,004,005, 0 10/0,020, etc. Try it slowly. I used to toss 1 hour and opened it. The feeling of that moment is indescribable!

If it still doesn't work, you have to go to the locksmith. Except for TSA002, the key to the customs lock is basically not available on other models (I searched).
