ok, maybe this is a stupid question - but wouldn't they have access to a TSA-approved key?
i also don't know how i feel about those TSA approved locks. on two separate occasions, i've had them ripped off my luggage. "they" (whoever they may be) ripped the whole tag off of the zipper and left only the part that is in contact with the teeth. needless to say, i wasn't very happy about that. after the second time, i stopped using the TSA-approved locks.
