Stuck locks I've heard of and experienced myself, but the key not coming out is weird. This tells me the pins inside the lock are seized and not allowing the key to come out. I would spray a little chain lube into the lock and jiggle the key to get the pins lubricated and release the key. Spray more lube, then put the key in and out a few times, like a penis in a vagina, just to get everything lubed up.
Graphite lubricant is the best choice for seized locks, but in a pinch chain lube or even WD-40 will do the trick without hurting anything.

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.
If it's like the situation with my 636, then your key is possibly stuck in "lock" position. Try this: push your clip-ons hard to the left, then turn the key counter-clockwise as far as it can go, then turn the key clockwise at the same time as you start pushing the clip-ons a bit to the right. The key should spring out of "lock" position.
