The lock cylinder cannot be disassembled; if replacement is required, a new cylinder coded to the old key must be installed.

On 1979-88 models, place the lock cylinder in the RUN position. Remove the securing screw and remove the cylinder.

To install:

  1. Hold the cylinder sleeve in the left-hand and rotate knob (key in) clockwise to stop. (This retracts the actuator). Insert the cylinder into the housing bore with the key on the cylinder sleeve aligned with the keyway in the housing. Push the cylinder in until it bottoms. On models through 1978, rotate the knob counterclockwise while maintaining a light pressure inward until the drive section of the cylinder mates with the sector. Push the cylinder in fully until the retainer pops into the housing groove. On 1979-88 models, install the retaining screw.
