I did a search on this site for "central module" and found several other people that have the same or similar problems with the remotes.

This sounds EXACTLY like what I have.
So, I called a local mechanic and he said that the computer needs to be adjusted when this happens, however, only the dealerships can do it.
I then called the dealership and spoke with a tech. He'd never heard of the "transport" or "sales" modes before. Not a good sign.
I have no other choice but to take it to the dealer and have them do a diagnosis. Bummer the average joe can't reset the computer....
BTW, the local mechanic said that a 9V battery connected to the terminals of the cigarette lighter would have prevented this from happening.
