Ignition stuck in lock position

When I tried to turn my car on at work, I had to turn the key a few times to get it to turn on, but it eventually worked. When I tried turning my car on the next day, it would not work at all. I have a key-fob and a valet key inside of it. I tried using the valet key but that did not turn also. I have also tried wiggling the steering wheel and turning the key but that has not worked. The steering wheel is not locked. Is the problem that I just need a new ignition lock switch? I have checked fuses and changed them out and nothing works. The only light that comes on when I put the key-fob in is the key and oil light.
