Try shaking the steering wheel side to side, and turning the key at the same time. The only problem you may have is just wheel bind, and the steering is jabbed against the steering lock. Hope this helps.
You start by putting the car's transmission in park. After this, you will hold down the brakes and then put the key in the ignition. Hold firmly the steering wheel with your left hand while the right holds the key. Turn the wheel to the right and left while at the same time while twisting the ignition key as if you are starting the car. This should allow you to turn the car on. If it does not work, contact your mechanic for more assistance.
