Okay so I just bought an 04 GTO two days ago with 126k miles. When I go to crank the car I have to hold the unlock button on the fob or spam the button with turning the key. If I do not then it will shut off immediately after cranking. I have read through the bcm threads and don't know if that is my problem or the problem is with my transmitter in the fob as my fob is pretty destroyed. Please help!!
