I had the same problem today - January 30th 2009. what i did was spray some WD40 in the cylinder and sprayed the key with WD40, then inserted the key in the ignition, then "lightly" and i mean "lightly" tapped the end of the key with the end of a wrench (my brass hammer was not in reach) 3 or 4 times. removed the key and then inserted again - then "all was well. the ignition turned, car started, and i will now wait till the next time something goes wrong with the car...

check the linkage on the transmission from the shifter. or not try wiggling the key up and down. if the cable is broken try to move the linkage on the trans all the way foward ( towards the front tires) with the tires blocked because it may roll. try it then.

Hi there,
try turning the wheel to the right/left while turning the key in the ignition. You have to apply some force. Your car is probably outliving its road life.

Cheers & Best Wishes

sounds like the key is either worn down to where the ridges in the key wont push the tumblers inside the key lock cylinder into their proper place to move the cylinder into the starting position. Or your steering colum is locked and the wheel is moving freely as if it were not. So your solution would be to either have an expert look at it (estimated cost: 200$ low/400$high) or you can attempt to fix it yourself.
should you choose the "I'll fix it myself" method....try getting a new key made at a hardware store since keys wearout over time (ie:10years of turning that old key), this may solve the problem right away if the ridges are just worn on the key. Or the hard way, you need to get a phillips screwdriver and some jewelers tools and an 8mm or 10mm wrench/rachet+socket to disconnect the battery, then underneath the steering colum just under the ignition is a hole in the colum shroud/cover, from there you can disconnect the ignition key lock cylinder (the thing you put your key into). once you've removed the cylinder from the steering colum you should test your key again to see if you can turn the cylinder outside of the colum if you cannot then buy a new ignition key lock cylinder for about 15$-30$...problems solved.
