I forgot to mention that I have the immobiliser 3 (p05107051AA)laying here beside the compurter.The guy at dodge dealership told me that if the chip in the key went bad or the other part that situation (I think that the other part is the immobiliser,Im not sure because I cant seem to find any information on it) any how he told me if either part went bad it would still turn over.He said just like the spare key without the chip.I dont have the(other key) to test tha therey.If anyone has a X-tra key w/out the chip would be so kind to try to start your car/truck and let me know if it turns over or not.If it does not turn over that would let me if thats my problem.I work for a living so I'm poor w/no money-so could any one help me bypass that chip. My old 1988 F150 starts just fine w/out a computer chipped key.

 

Welcome to the site. I will move this thread to the second generation Neon section,
FF

 

Welcome! First, the F150 doesn't have chipped keys, which is why it will start without one. Second, a Neon will turn over and actually start for about 3 seconds with a non-chipped key. It will then shut itself off.

 

yup, it will start and run, for about 3-5 seconds and then shut off

 

Apparently this is different than other makes of vehicles, Example is the 2003 Chevy blazer. Nothing happens except the instrument cluster goes berserk and flashes "SECURITY" in the Odometer LCD.
Fords do the same thing.
But as I've said before I'm a Mopar N00b.

 

Yes, each make has their own system that can and generally do work differently.
