The key will not turn to start the car. the steering wheel is locked but the key will not turn even though I turn the wheel slightly.

SOURCE: ignition cylinder won't turn

I had the same problem in a 94' trooper. Basically the Ignition lock cylinder is wore out and you need a new one. Mine wouldn't turn past lock and no matter what I tried it wouldn't turn. You can go on auto zone and find the part, mine was about 61 bucks, it comes with keys and the ignition cylinder. The deal is that to get your new ignition cylinder in you have to get your original turned to off or acc I can't remember. You'll see with your new ignition cylinder that when you turn the key there is a button that can be depressed but only when the key is turned past lock and it also won't depress in start. First, disconnect battery and wait like 30 minutes. So, what you do is take a screwdriver handle and place it up against key and take some pliers or something and beat on it a couple of times, this gets the key in deep enough to where you can eventually turn it. I swear it will eventually turn, once there, take off the top and bottom plastic covers off steering wheel/unscrew electrical wires on back of ignition cylider and other side and you know the button I referred to basically you have to depress that with key in acc or off and it will slide out. If your having trouble finding the button look at new ignition cylinder in comparison to old one and you can see where the depressed button is on side closest to you, you'll see a little hole up on the side of housing that you can depress.
