Yeah, you're right about that. The entire Mitsu delarship that I'm dealing with is pretty sleazy, I didn't learn this until the after the fact. But, then again, what car delarship isn't sleazy? They're in the business to make money and helping out the little guy with the little Mirage is not in their agenda.
I digress... I do have an update, I didn't try to resync the key but I found out that when I put the ac on full blast this afternoon I didn't have the issue. So this has to be heat related.
