Re: key fob won't work, alarm goes off - stuck!
Even though I own a real Mercedes they will NOT service the Xfire. You can call the one in your area to see. We have 3 and their response was we only service cars with a star on them. But the good news is an independent Mercedes mechanic will do a good job on the SKEEM. They are not cheap. Labor can be expensive. They have to take the dash off.
