Welcom to the forum.

This is a very common problem on the pre-2015 that I have seen on this forum. Basically what happens is either the battery dies, was disconnected and/or replaced. The result is either the car won't start, or starts but the keyfobs don't work. Problem is, I have seen lots of posts saying "my battery died, I replaced but car won't run" and they never seem to come back to state what the fix was.

Now on 2010-2011 models there was a recall on the WIN module, which could be the problem if the car does not start. However, there was a member on the HP tuner forum that recently disconnected his battery on his 2009 and the car would not turn over. Turns out it was a loose connection.


Now if the battery was completely discharged it is a good chance the battery will need to be replaced as one or more of the cells could have gone bad.

That said, what are the symptons...engine won't crank, engine cranks but won't start, engine cranks and starts but keyfobs don't work?

Guess I was extra lucky. My 2010 RT battery lasted 9 years, 2 months. It grunted one morning but started so replaced it that afternoon. ZERO issues....

Mine died after 7 years. It was embarassing because it occurred while my 2009 SRT was undergoing NJ state motor vehicle inspection. It had to be pushed out of the garage! I replaced it with a Bosch AGM battery.

So a word to the wise, replace your old battery before it strands you someplace.
