Not sure if anyone had this problem before or not but, my security stays on when i put it in the on position. It would crank but wont start. I would need to insert the key in the ignition to start it up. I know someone that works at the dealer and he thought it was the bcm but that wasnt the case and now im stuck with a brand new genuine bcm. I have also replace the battery on the keyfob too. He tried to reprogram the key but he said it wouldnt let him for some reason and all out of idea of whats wrong with its beside its some kind of electrical problem. Fyi, the spare key doesnt work also.
