Hey Guys,

I seem to being having some with my 04' crossfire, im not much of a car guy so not really sure whats going on, but to make sure i wasnt wasting anyone's time I read a majority of these post and some youtube videos.
The problem started 2 days ago go to get in my car, doors wont unlock from the FOB, try to unlock with key, and alarm just goes off, eventually get the alarm off and try to start the car (found out from post dont do that) well obviously doesnt recognize my key so car starts and turns off, get new batteries for the FOB and I read all the FOB instructions and restart the computer by taking off the positive for a bit and reconnecting and then pressing open twice and then inserting to on position, and attempt to start car, does the same thing, turns over and then just shuts off. Made sure batteries were good Red LED lights up, had battery checked seems to work fine. Starter seems ok since car turns over, both batteries are OK.
Now question is what should I do, i read most peoples post that had this problem and they simply grounded the cables and everything started working, but after grounding and everything my FOB wont work but the key does turn the engine over but shuts off in like a second. Oh also I took apart the Key FOB a few min ago to look at the chip and nothing really seems to be wrong with it and no one can really tell me if the chip is fried but i doubt it.
What should i TRY NEXT?
