One TSA002 and one TSA007 master key for TSA locks. If you only need one, it is listed separately as a single item. Please check your lock or key to see if it is marked TSA 002 or TSA 007. These keys can also be used to unlock locks if you forget the number. Basically, these keys can be used for all TSA002 locks, but please note that they may not be able to unlock locks if the lock or keyhole is damaged. Please note that these keys may not work with TSA002 locks on Arnold Palmer suitcases from about 15 years ago.
