2006 VZ Commodore

Just replaced the ignition barrel at my local locksmith and still having issues on the start up. As if it’s got a flat battery, the fellow doing the ignition suggested getting the sensor that the barrel goes into on the other side of the barrel. So I that sensor in my hand about to undo that small star drive screw and thought I might double check if anyone else has done this and any trick in doing it.

Cheers brothers

1. Disconnect the negative terminal of the battery.

Use a T8 driver to undo the grub screw.

Also remove the contact ring that connects to the key when it goes in.

Clean it out. (I used contact cleaner) Make sure it is springy and not jammed.

*Theres no actual sensor. It’s a basic switch which is the same from VN-VZ.

Immobiliser, that is controlled by the PIM which is located up under the instrument cluster.
