thanks everyone...but it's not the lock cylinder. My key works fine. My lock assembly is jammed or broken. I don't want to pull the lock yet because I want a replacement to do it in one shot. I already pulled a pass side just to see what the problem might be. the push pin doesn't work period. A car will lock and unlock manually as long as the door actuator is disconnected.
In my case I know it's something missing or broken in the latch mechanism.
