You should be able to get a new cylinder from the dealer. With proof of ownership, it can even be made to work with the same keys. It may take a few days to get it in. I can't access my service manual, so I'm doing this from memory, but I think that there are only a couple of easily fabricated tools needed to get the cylinder out, the dealer would know better.

Good luck

You might also want to check in at the other place (google benzworld 107 forum) for more resources.
