Key wouldn't turn for hours/Wheel Locked. (possible key or ignition lock cylinder?)

[Elliesue]

Started having the same problem with my 2005 Saturn Vue. I had been using the same key for 8 years and tried the spare. That worked for a couple of months and then had the same problem - the key wouldn't turn in the ignition. Tried WD40 and then a shot of canned air and that worked for a short time. Key was still sticking. I called the local GM dealer and brought the car in today. Much to my surprise I was told that I would be given a new cylinder and keys (which had to be ordered and will be here in a few days). Also to my surprise I was told that there will be no charge, since this was covered in perpetuity under an issue years ago that Saturns were having. No complaints there!
