There is currently locks on the cases with no keys, however they are unlocked and can easily be removed to place your own lock on. You could take the original lock to get re-keyed which could work out wonderfully if purchasing more than one case.
I have 4-4ft cases, 2-3ft cases and 2-5ft case. All available except one of the 5ft cases needs top glass replaced. Would be easy to replace since its rectangular and will drop right into its slot.
