The ignition switch in my (purchased new; we call it "The Tank") 1997 FZJ80 locked up on wife when she had it parked on level ground at her horse stable. Neither my wife's key nor my key would work. Inserting the key would not unlock it, and of course the steering wheel and transmission remained locked up. Neither my wife's key nor my key would work. After several minutes of jiggling the key back and forth in the ignition switch while shaking the steering wheel back and forth, the ignition switch finally let loose, and I could start the truck. This happened once before last year, when the rig was parked facing downhill on a very steep hill, and I had left the wheels turned all the way left. In years past, I've worn out several ignition keys that stopped working at some point; I assume that the keys are intentionally made from softer metal (brass), so that they wear out before the switch wears out. Do you think that our two keys are just worn out, or could something else be the problem? As mentioned, I purchased it new, and the rig only has about 135,000 miles on it -- not much for a nearly 30-year-old Cruiser. The rig has been all over the world during my Foreign Service career, but doesn't have much visible rust (except underneath); it practically looks showroom-new.
 
It'll be a major rebuild to get it right, send me a pm when you're ready to sell.

In the meantime, you may already know this but if the steering wheel was turned significantly to either side when the engine was last shut down
there can be pressure against the ignition switch-steering interlock (inside the steering bracket/ignition barrel). When that happens you need to rotate (turn) the steering wheel forcefully in the same direction the wheels are pointing (ie far right or far left) and hold it there before attempting to turn the ignition key. By turning and holding the steering wheel it takes the pressure off the steering lock pawl inside the steering bracket where the ignition cylinder is located. Clear as Mud?

The original ignition key can get worn or if you're using a key that was (poorly) cut from the original, either situation can cause problems, but with
the low mileage that's less likely.

I had that happen to me once about 10 years ago when parked on a slight incline on a driveway. Worked just as you described being unable to get the key to turn. After about 10min of jostling the steering wheel around for and against the direction of tires, the lock finally rotated smoothly like normal and started right up. It's a combination of internal resistance on the lock mechanism, I'm convinced.

Never had it happen again. I'm sure it will happen the next time I drive it,... 🤣
