Key won't turn in ignition, ignition locked, but key will come out on 2004 Chevrolet Impala

I took everything apart and all wires are good, fuses good. So I guess I'll have to get new ignition lock cylinder, but would the lock cylinder cause the problem w shifter nob not popping out all the way? I also noticed that my battery (positive) screw is stripped so I put a charger on it and noticed there is no charge on positive side. Would that cause all the problems?

If it's a floor shift, talking about knob, the shift linkage might need adjusted so it will go all the way in lock position. The key not turning is most likely a worn key, or lock cylinder. Very hard to remove if the key won't turn. If key is worn you can get a replacement at the Dealer with your title as proof of ownership.
