Note that, on certain models, the spring clip must be released by inserting the tool through a small circular hole at the top of the switch housing, above the rectangular slot shown. Slight movement of the key may be necessary to allow removal of the barrel and cylinder.

4 To remove the lock barrel from the cylinder insert the key fully into the barrel and remove the retaining circlip, taking care not to damage the circlip location, then withdraw the key approximately 5.0 mm (0.2 in) to retract the lock barrel securing lug, and withdraw the barrel from the cylinder.

5 To remove the ignition switch, disconnect the wiring plug, then remove the two grub screws and withdraw the switch.

Refitting
6 Refitting is a reversal of removal, bearing in mind the following points.

7 Note that the lock barrel can only be fitted to the cylinder in one position, and check with the key fully inserted that the barrel can be turned from position O to Ill satisfactorily.

8 The open jaws of the lock barrel retaining circlip must align with the keyway register on the cylinder, and the cylinder retaining circlip must locate in the slot in the ignition switch housing.

9 On completion, check the operation of the steering lock and ignition switch in all positions.
