Default Help! Key won't turn in ignition!

What in the world happened? 94 SC400...97K miles...absolutely no problems until yesterday. Key WILL NOT turn in ignition. Tried both keys...I am aware of the 'wheels turned against steering wheel lock' issue- wheels are straight and the steering wheel is free to turn (or, was until it locked as I was turning it...) The auto tilt works properly. I checked iATN to see if there were any pattern failures, nothing mentioned. Has any one seen problems with these ignition switches before? I searched the posts here for problems, did not find any...
HELP!
Thanks for your time-

Thanks for the replies, but still no go. It will not come out of park without the key in the acc or run position, and I can't turn the key! Turning the wheel either direction doesn't help either...
Please keep the ideas coming!

before you do that..^ are you trying to turn the wheel from side to side WHILE attempting to turn the key?

and about the shifter, use a flat head screw driver and there is a lock override switch under the little black square in the top left. use that and put it in neutral.

In the day it was often said "you NEVER oil a lock". Rxcept when it is jammed up with hardened oil applied by someone that didn't get the message. Aliga is right on both his suggestions. May I add: Get a an of carb cleaner withg the tiny red spout that will fit inside your lock. Spray the heck out of it and keep a rag up against the outside to prevent the spray from dripping on the plastic. Run your key in and out briskly while the cleaner is wet. IT this is going to fix it it should be free at this point. If it does free up squirt another dose in there. Don't use WD 40 after you get it working....go to a lock shop and get some genuine LOCK LUBE. WSD is a great idea to FREE up a lock though.

Good luck,

John

my 92 sc400 is having the same problem. I've had a mechanic and a locksmith look at it and tell me i need to replace the lock cylinder. How am i supposed to get the cylinder out if i cant turn it to ACC in order to remove it?
