The ignition is tough to replace. you need to remove the airbag and then the steering wheel and the turn signal mechanism all while making sure you don't lose any screws down the column and then you have to put it all back together. A lock smith won't do anything if the ignition cylinder won't turn. BUT, how far are the wheels turned? or are they straight. If they are turned, the steering wheel lock may be stuck, turn the wheels further in the direction they are turn while at the same time turning the ignition.
