steering wheel - alignment

I took my car for its first drive last week and my steering wheel is off. When going straight the wheel it turned about 2-3" to the left. The previous owner drove the car and I didn't do anything with the front end alignment. I had the steering wheel off when I was troubleshooting the turn signal switch and I though it was keyed so it only when on at one position, but can't remember for sure. Before I tear it back apart can anyone confirm if it does only go on one way or if it can be reposition? If not than I'll just have to have the front end aligned.
