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.

My 2010 SRT8 just started doing this today. Went to the dealer and thought I'd solved the problem by purchasing a new battery for the key fob but filling up my Chally 15 minutes later it quit on me again (oh bother). Going home and restarting the car using the remote push button it started up fine for me so after all this reading I've concluded this is another intermittent problem.

1) Have any of y'all tried using a better (more expensive) remote as a possible solution? If so then what fob make did you chose to use & why? I ask because the above referenced response says the Dodge key fob as "cheap" and may not be up to the task at hand.
2) Is this issue related in any way to tuning issues or emission testing issues?
3) What common tactics are the dealers using in order to solve the problem? I do have a good dealer at my disposal but I still would like to "nudge them" in the right direction if possible.
Any & all advice is greatly appreciated. Thanks in advance!

i would like to know why this is a problem that many of the cars are experiencing, but yet it isnt ready to fix when we go to the dodge dealer. i just purchased my srt8 less than amonth ago, and yet i took 10 mins to open it with the remote for work today. i was pissed because my mom yelled at me for not going back to the dealer and throwing it in their faces.lmao. but i will go t the dealer monday because i am still under warranty.

lets just hope i dont run into an emergency and the car cant start.............

If it will not start w/ the remote have you tried popping the start button out and using the key? Just a thought.

Just so to be clear, the hidden key from the FOB will only open the door. The FOB must be inserted into the hole in the dash to start the car and this does not depend on a battery in the FOB to happen, it's a proximity type of thing.

its not starting the car thats an issue, its unlocking the doors to get into the car as the issue. and with both remote keys. after the car gets unlocked, then there is no problem turning it on with the remote start or the push button inside.
