Your profile says, "Currently looking" so we don't know what make or model your Airstream is. But if it's not vintage, you may be able to order a new lock, with keys, direct from Airstream, or through your nearest Airstream dealer.
Failing that, going along with the lock on the door should be a strike plate on the doorframe that engages the bolt that slides in and out of the lock when you turn the key. Your problem might be solved by adjusting the strike plate to align it properly with the lock's bolt.
