These locks are TSA approved and can be opened by the TSA (and anyone with a basic lock-pick set).
So -despite the post-911 rules- you can lock up your unicycle hardware while flying.
I wouldn’t trust my luggage with one of those on it, especially if they can all be opened with the same key. Any moron with a file can easily buy one and make their own masterkey.
Even without the key thing I would trust these kind of locks.
But keep in mind the only other option you have is having no lock.
yeah seriously thats the whole point of this lock to let the bag screeners open to inspect it.
