My 2001 Alero's ignition switch key cylinder looks to be bad, I am unable to turn the key from the off position. I have everything removed with the exception of the shift lock cable. I have depressed the lock tab as discribed on another thread in this forum, with no success. I am wondering if the key has to be in the on position before the cable can be pulled out. Any one know or have some helpful guidance?
Also, if the key cylinder is bad and cannot be turned to the on position. Is there a way to remove the lock cylinder without destroying the switch module?
Thanks
