Key in ignition chime
If your key in ignition chime annoys you there is an easy fix.
Remove the shroud under the steering column
Turn the key to red lights on the dash
Push the little tab under your column that is on the ignition barrel and pull the key out, the whole barrel will come with it.
Look in the hole the ignition barrel has left
You will see a small black tab. Grabit with a pair of needle nose pliers and twist it as though you are trying to turn the key off untill it snaps.
Once it is gone you will have to turn the little barrel it sits in till the red lights ate on the dash again.
Insert the barrel along with the key and it will clip into place.
No more dinging.
Screw the shroud back on. All done.
Hope you enjoyed a little aussie ingenuity.
