Bought my 07 g35 coupeAT about 4 months ago, out in the streets. Everything seemed to be working fine, no problems till I decided I wanted to add a subwoofer to my coupe, so of course I disconnected the battery. After I finished my installation I connected my battery back and now my ignition switch is frozen 😞 Won't turn at all ,steering wheel isn't locked because I can turn It a little. Not sure what can be the problem I'm stuck. Also when I bought the car it only came with the keys no FOB because they were lost.
