Bongo Fury

As I've said, during our travels through Spain, we got 'done' by the usual band of robbers. They got into the Bongo by screwdrivering the passenger door lock - very little obvious damage, but that door no longer accepts a key. We can live with it, as the central locking still works, and the passenger door can be opened and shut, but not with the keys. Can anyone help with whether we can get a replacement lock that will gel with the system? If we claim, I think we'll have to have the whole system replaced, mucking up our no claims and our next year's premium. Any advice appreciated. Malabar.
