TSA says to not use TSA locks on gun cases-


"Firearms must be unloaded and locked in a hard-sided container and transported as checked baggage only. Only the passenger should retain the key or combination to the lock unless TSA personnel request the key to open the firearm container to ensure compliance with TSA regulations."

"TSA approved locks compromise the security of your firearm. Remember, the law states that you ALONE maintain possession of the keys to your gun case"

i used a heavy duty pad lock

and carried a spare
