my father inlaw had a aveo that did the same thing but they had built in an override button near the shifter that you had to depress to get the key to unlock. upon taking the console apart it was found the "park" sensor was broken and had came loose from the housing. the car would think the car was still in gear and wouldnt allow you to turn the key to "off"

 

Do you know what the part number was for the wire?

 

Hey Midwest girl do you know what the part was that you needed to fix this? As I am having the same issue.. I have tried everything and nothing's working

 

Help my key won't come out of ignition stuck on acc tried everything.

 

My friend’s Captiva is doing the same thing. Randomly draining the battery, she says the radio is turning on by itself and the keys aren’t in it. Any help would be most welcome, Melinda!
