You avalanche may be in security mode. If this is the case, you will have to call the dealership and get the code. If that is not the case, you have a bad ignition. You will have to change your ignition box and lock cylinder. Make sure your shifter is all the way up, just in case the cable broke.
hey RichardI was reading your post. I have a question. My son grabed the gear shift on the steering wheel of my 2003 avalanche and busted it off. I have replaced it and the big orange wire going down in to the box. But the key is stuck into the ignition and will not come out or turn. What do you think I need to do now? Thank you Tony
where do you enter the code if its given to you by the dealership?
