If I am reading you right, you are having trouble turning the key itself?
As above, try the other key first. Then try moving the steering wheel a bit. Sometimes, in some cars, the wheel gets intself into that exact position that it locks up the ignition. My T-bird was really bad about it. I don't know if our cars have this issue, I expect not due to the ignition placement.
My mother'* Escape was doing exactly this for a while. Really obnoxious. Eventually she had to have the dealership replace the ignition switch.
