I put the key in the ignition but I can't get it to move beyond the "I" position.

some of these electric interlocks require the brake pedal stepped on for releasing..have you tried that? along with shifting fully into park a few times?

Try rotating the steering wheel; it may be inline with one of the locks.

you never describe what type of fuel does your car use... is it a diesel or petrol engine? if its a diesel engine then i have the correct sollution that can help you. the problem will be on the injector pump, on the main switch. change the switch and the problem will be solved. or check whether power reaches there. when it reaches then is the injector switch doesnt work to close the main valve that the car can switch off. all the best

sound like the tumbler is falling out, when you open the steering column there should be a hole where a small but solid object can go in.. this release the tumbler but only when the key it turn at a certain position you will feel the pin in the hole go inwards then you can slide it out...it could be defective or just need to place back properly..hope this help..

turn the key around and insert it ,when you turn it should work

you have to turn the steering wheel a little back and forth hard until it releases it probably locked in hard when you parked it there is tension on it just move it back and forth some and it will release
