    Q:
    Are there any specific instructions for the Ignition Lock Cylinder of the 1990 Oldsmobile Cutlass? Posted by Mohammad D.
    A:
    Yes, for models from 1979 to 1980, the lock cylinder should also be removed in the 'RUN' position, followed by the removal of the steering wheel and turn signal switch without completely detaching the switch. The ignition key warning switch should be removed, and the lock retaining screw taken out with a magnetized screwdriver, ensuring it does not drop into the column.
