We attempted to manually lock and unlock 2 passenger side doors, and now the rear lock doesn't work, and the rear door also doesn't open at all, from inside or outside. In the front, the door can still be opened but the lock has to be manually locked and unlocked. The drivers side 2 doors and power locks work ok. The vehicle was stopped when we manually locked and unlocked the passenger side doors.
After parking the car (2010 Chevrolet Cobalt), the key would not come out of the ignition or turn to the off position. The car is a manual, so I had to stall it out and then unhook the battery to turn everything off. It is awaiting diagnosis at the mechanic.
