Had it verified by the dealer that my remote control keys won't start the car because the AAM is blown (this is an EAM after '98) - I'm being told that if the car was jumped "incorrectly", this was the cause. I had AAA come out when I got stuck a couple months ago, and the battery would not jump, and did get replaced. I can only use the valet key to start the car.

Service advisor says, that's why there's roadside assistance and that they "never" jump a car, just replace the battery.

Two questions:

1. What is this AAM ($500+ part & labor, to replace and recode keys!)? They said it's under the fuse box, and that it could affect other systems. Would you DIY, or not mess with the electronics?

2. Here's my beef - the owners manual says nothing about not being able to jump these cars because of "sensitive electronics", (also a mention from the advisor), so I think MB has some responsibility here, no? What about AAA, anyone know if they are insured for such (supposed) mistakes?

We should all be looking forward to hearing about this one!
