How do you change the key lock cylinder on 1991 Chevy Corsica?
If you are talking about the ignition lock cylinder, the steering wheel must be removed and the column disassembled to access a lock screw which holds the ignition lock cylinder in the column. No key is required for this (unlike all other vehicle manufactures). If you are talking about the door lock cylinder, the door panel must be removed, and the lock cylinder retaining clip must be removed (again no key is needed, which is the same for all manufacturers). If you are talking about the trunk lock cylinder, it is easily accessible from inside the trunk. Those are the only types of lock cylinders in this type of vehicle. There is no specific lock cylinder named key lock cylinder.
