2002 C320 key won't turn, door locks don't work after jump starting. SAM bad? - PeachParts Mercedes-Benz Forum

After trying to jump start this 2002 C320, the key no longer turns in the ignition, nor do the door locks work. I had the car towed to a Euro car repair shop, and they said the EIS was bad. I suspected that was not the problem, as other things did not work either. They took the EIS out, and I sent it for repair. The key shop tested it, and said there was no problem with it. I believe that the SAM is bad. The question is, if I get a new or used SAM withe the exact same part number, will it work? I do have a STAR C3 computer and hardware, but I am sure the ignition key needs to be working for coding to be done. If I replace the SAM, will the existing EIS communicate with it? Any help will be much appreciated. Thanks, Rich
