Determine if the cable is opening/closing the appropriate doors. Sometimes these doors rust, inhibiting full operation (it also squeaks when going through the range of motion). One of mine had a rubber 'seal' that fell apart from age so I replaced it with soft leather.
These cables have adjustment 'takeups' for fine tuning.
BTW, did you pull your tumbler out of the defective key switch?
