I am sorry that you have not been helped yet. I just came online and saw your question

Does yours have both the factory alarm and the factory immobilizer/anti theft system? If it does, you cannot disable the alarm without disabling the immobilizer system as well which puts the vehicle in a no start condition until it is reprogrammed with factory scan tool and software

I have no idea. How would I find that out?
Expert:  Eric replied 1 year ago.


When you turn the key to the on position, there should be a small round light that comes on directly between the fuel and temperature gages(see attached) and then goes off. If yours has this, it has the anti theft/immobilizer system

Customer: replied 1 year ago.
it has that. So what do I do about turning the alarm off
Expert:  Eric replied 1 year ago.


Because the anti theft/immoblizer and alarm are incorporated into one system, you cannot just turn it off, otherwise you disable the starting system as it will prevent the engine from starting.
