The "Ask a Mechanic" Thread in The Tailgate Posted April 10, 2010 · Edited April 10, 2010 by Veretax you could try flushing the lock cylinder out with wd-40 and trying a spare key.I'm assuming you already tried wiggling the steering wheel back and forth?? You likely will need a new key cylinder which is more than 10 bucks,but sometimes flushing it out works directions http://www.2carpros.com/forum/2000-chevy-impala-ignition-switch-issues-vt68221.html (the disconnecting the battery part is important since it has pass key security) perhaps call the dealer and see if there is a recall...springfield might know,it seems a common problem. WD-40 into the locking mechanism? that's an interesting thought. Yeah we tried moving the steering, it wasn't locked up and i could move it in either direction fairly far, didn't make a difference. Although We did try my wife's key while we were still stuck. The mechanism would seem to sense the key was there as the lights would change as they normally do internally, but it still would not turn.
