She's an 04, so do you still have factory warranty on this vehile? If so let
the dealer worry about the parts an labor for this issue. If you dont, I
will let someone else tell you how to fix this. Its not real complicated,
but it can be a real pain to do. I would try to turn the wheel hard to the
left or right, so see if the lock is just really tight. I have a habit of
rolling the steering wheel when I first get out of my truck, and as a
result, I end up with a very stiff wheel lock the next time I start the
truck, and I have to pull (sometimes pretty hard) to get the wheel unlocked.

In a '04 I'm sure it's different than the one IdaSpode showed a picture of.
But that was the part I was thinking of.  I'll bet in an '04 it's going to
be a shop repair.  Especially if you've not done one yet.  The older ones
were pain enough.
