I don't use a lock, I use plastic zip-ties. They can open it if they need to (which is true of any lock) but it keeps folks with sticky fingers from browsing around, and keeps it from opening by accident.</font>
But how do you remove the zip-ties?
Easy - use a pair of scissors or knife.
BUT WAIT! You can't pack those in your carry-on, right? So you pack them in your checked luggage - which is sealed by the now-impenetrable zip-tie!

just poking fun. It's a good idea.
