MDP seems to have the answer for this snafu. Their support email is up on their website along with their request for service form. Be smart and sign it - I forgot to and there was a back and forth that was my fault - not theirs. They need the Skreem module, ECM and all the keys. Also the documentation to prove ownership. When it arrives just plug it back together and it should work. I'll post more when I have a chance to drive it around, but it worked fine at the shop and I expect this is the solution. MDP obviously cares about solving this and will give you any help you need to see it does. The shop where it is now works on MB and other cars and their MB scanner plugged in to the OBD port, and showed no codes when scanned. All lights and doors working as they should. Nothing to do with the keys - they are ready to go. I think the cautions I've read on the Forum about disconnecting the battery for the install, and having a good battery are worth following. I' m putting in a new Interstate battery just to be sure.

I have nothing to do with MDP and wouldn't understand what they did to it (which they won't do.) Anyone needing this service should just contact MDP via they support line and follow their requests for documentation which you can include with the parts when you send them to them.

Important to note: FCA (Chrysler now) did absolutely nothing to help us find a solution, and dealers couldn't care less about our plight. Probably they don't have the MB software to monitor codes, and of course MB won't help with any of this. If/when Chrysler ever comes up with some new modules it may be prudent to buy one and have MDP look at them to see they work for the specific car - I don't know anything about that. But if you have a non-op SKREEM module or the symptoms we all know about - this appears to be the solution to use, and will probably be less expensive than getting the SKREEM from Chrysler anyway. Screw these companies - they left us sitting and their inattention to our predicament was evident and threatened our ability to ever use the cars.
