The power steering pump could be bad or the pressure sensor could have failed or even the belt could be loose or have come off the pulley. In enay case the power steering assist fails and the steering becomes heavy. The ignition lock has a pin that keeps the wheel from moving when in park postion or, "OFF". This pin can get caught against the pin catch and if the steering wheel is hard to turn it will not move unless you can move the wheel which take s alot of effort. Also, the fact that the pin isstuck in the steering wheel lock keeps it from releasing and will keep the igntion switch in the, "OFF" position.
Someone who is a bit of a strong guy can probably move the wheel enoguh to release the key. The pump needs to be inspected for the belt and tension and check the fluid level as well as checking for leaks.
