See my profile....I do not know much about your rig, I am a CJ kina Guy.
I'm sure some of this has been attempted...But here goes!
Pull/ turn the steering wheel either direction while trying the key thing.
If you have "TILT STEERING" tilt both directions, don't slam it, but do it with a purpose...while doing the Key thing
You may also check linkage to your tranny, for like foreign objects wedged in......simply shaking it may un-bind it.
Other than that EZ stuff, consult a repair manual for other parts that would affect you.
Your key switch may be messed up....have you/ can you.... tried a different key?
Let me know what happens....With GOOD NEWS!
