I have had troubkle getting the key in but never out. That's anew one. Anyways my problems were always fixed with a goodly application of a spray cleaner like wd40 followed by a quick spray of some kind of lubricant. should work for getting it out. Spray first then gently try and move the key around (don't get too forceful, they do snap, then you really do have a job). Spray again, repeat until you feel something budge, which it should.
