Car having trouble starting but everthing else works even without key

97 pontiac grand am se v6, a while ago my car did not start, I guess it was the ignition switch. So it got repaired but then the other day it wouldn't start. And it would not shift out of park at all, but when I went to take it to the same shop everything worked but I took it in anyway. When I got it back it ran fine for a day, then my radio, wippers, defroster and dome lights would not work so I checked the fuses and replaced one and it started and everything works even without the key. Now its having trouble starting it starts in about 1 in 30 trys. Can anybody help me?
