When I go to start my car. I know, I programmed an aftermarket key fob and come to find out. That was a bad idea that before it stopped starting completely, it had intermittent starting. So I've to my understanding, it has something to do with the car. Key mobilizer, antenna that is either broke inside or just too old inside of the steering wheel where the key goes in or when I program the aftermarket key fob, I somehow made my car think that I'm trying to steal it and will not allow me to start the car, what do I need to do should I completely replace the whole immobilizer system? As I've already checked almost every single. Fuse, except for whatever the information is underneath the steering wheel, the panel that you have to pull out, that has the soldiering on it to find out if it's sad or not. That's where I have stopped to find out to issue.

Hello,

We can help you get it going again. The first thing we need to know is while you are cranking the engine over does the security light flash? If not the immobilizer is not the problem, if so lets reset the system, this video we show you how.

Holly crap, i pray this works. This is the one thing i javent tried oddly i did unhook the battery but i didnt know aboit this trick. This is what ive done. The first time it did blink, 3 times to be exact, after that it didn't anymore. Ive already check the main fuse box under passenger side hood and the fuse box on the left side of the drivers legs. I have not checked the one under the steering column or have i went as far to physically check the ring around the ignition key portion. I also tried resetting my main key by the switching of 0 I II ON, between the I and II with in between locking and unlocking the car door.

I pray this works. Ill be doing this tomorrow because its been at my work for 4 months trying to rack my brain and about to buy what i thought i needed. Ill let you know tomorrow evening. Thank you
