Check your safety neutral switch on your transmission
My GMC Envoy started working after replacing the ignition switch. It would not completely disengage electrically, but I could take the key out. The radio remained on and the car seemed to think it was in reverse, yet there was nothing wrong with my neutral safety switch (PRND) and the cable was fine from shifter to tranny. These vehicles have lots of electrical gremlins.
