Don't know if you still need advice. Put the rest of the key in the ignition, sometimes the steering wheel is loaded up and you need to turn the key while trying to turn the steering wheel and see if that takes the pressure off. Another trick is to put super glue on the end of the broken key and quickly insert it into the lock and let it set for a minute. Otherwise you have to pull the steering wheel to access the lock set screw. One very, very important step is to disconnect the battery for about ten minutes to avoid possible air bag deployment, no fun.
