Worn or badly cut key, wheels turned cramping the steering wheel so that there is pressure on the key cylinder. Cylinder itself bad.
bad coil pack on cylinders, find or pull ignition wires and you can tell by no loss of power.
low or no oil pressure
If you have a steering lock, that can lock your steering wheel in place, until you use the key in the ignition to unlock it.
Check the valve timing and the ignition timing. If both are good then check the compression in all the cylinders.
I am not sure what causes this, but I have had times when my ignition key would not turn. The solution to the main problem is to turn the steering wheel slightly. This usually allows the ignition key to turn.
Not running on all cylinders? Bad spark plug or wire? Bad ignition coil (if C.O.P.)? Bad valve? etc.?
because you run them to hard and it causes wear and tear. Specialy when you drive alot at high rpms it causes metal to metal.
because stupid, YOU GOT THE WRONG KEY Typically, the most common reason for the key to be "stuck" in the ignitions, is that the steering wheel is turned from the center position, which causes the ignition interlock feature to be "jammed". By manipulation of the steering wheel, to where there is no tension on it, will usually allow the key to be moved to a psoition to where it can be removed.

It was the dis ignition module changed it out and runs great!!
low air pressure in your tires. fill 'em up!
This means you have excessive pressure on one side of your power steering assembly. Your steering box may be worn out. Also, check your tie-rods for excessive play.
