The problem is that the encryption software (Keeloq) doesn't do well with cheap electronic parts. I spoke to one of the architects behind KeeLoq a few years back when we first encountered this problem, and he told me that Chrysler decided to use cheap, foreign, electronics parts, so that's the cause.
The fix is to re-flash the WIN module. The new programming is believed to knock the encryption to a much lower level and thus leaving the car less secure. Presumably, the car communicates with the key fob better with lighter encryption.
Still, if the WIN module (behind the dash next to the steering column) heats up, i.e., the car sits in the hot sun for a long period of time, then you're going to experience the problem again, regardless of whether or not the car has been re-flashed.
Hhhmmm....maybe that's why it only did it when I was in Florida? No garage, just covered parking.
We will see what happens when it's not in the garage now that it's getting warm here in NJ.
