Cobalt This sporty compact was faced with the difficult job of replacing the popular Cavalier, but whether the base model, or the supercharged SS is chosen, is has made for a great replacement.

Default Locked Cobalt GM radio

Does anyone know how unlock the GM radio part number 15851728 off a 06-07 Cobalt¿ Or how you would go about entering the unlock code, because even I tried entering what I believe might be the code it doesn’t do anything or say anything or completely lock me out after x amount of tries like it’s supposed to and pressing any button doesn’t seem to do anything. I’ve also heard that I could remove a chip to unlock it but I’m unsure as to which one if anyone knows for sure which chip could you let me know, I’m between two 8 pin chips but am unsure, thanks.
