Need help my nissan maximum went start and the key wouldn't turn and wheel wouldn't
 

My Nissan Maxima 2004 randomly just stopped working I got in out and went to start it, but the key wouldn't turn and the wheel was locked nothing would unlock, the key wouldn't even turn, to the on/start position, I cut the steering wheel lock off and after that the key would turn but the car still won't start, in checked all the fuses and relays grounds and battery to spark plugs are good but the car acts like it's having trouble turning over. Any ideas would help because my cars sitting on the side of the road!!!
