USA Trip

For the coming US trip, I bought a TSA security number lock for my luggage. Thinking it would be easy to set the lock, boy was I wrong. It didn't work! Worse, after fiddling with the lock for a few times, even the preset lock of zero couldn't be used too. Ahhhh. :(

Going to get help from a friend to try to unset the lock. Hope friend will be successful.
