I tend to think that car might have have had the "SKREEM DELETE" done, that, and I suspect the CLP/SSM is water damaged -but it is VERY hard to say, as it sounds like (as you were told above) that the car has been modded or damaged in some way.

I'd just contact the the MSS and see if they can help. I KNOW they can make keys for you, they make keys for Crossfires every day.
Just do not expect the services of the MSS to be free - they provide a service and they charge for that service. IF we could help you for free, we would.
