They key lock isnt actually a barrel, its just a switch, you can turn it with a key, screwdriver, anything flat.
I had to swap the loom from the glovebox over as it didnt have the extra plug in, but it was all in my car loom. Some cars have it in the car loom and some dont. i found an old thread with a search that said the way to check if your car is retrofit ready is check the plug going into your overhead light and if it has pins in 4 & 7 then you have, as thats the signal for the passenger deactivation light, and i did if not its ALOT of wiring.
im going to have to plug vagcom in though as the airbag light is now permanently on so may need an activation/reset.
That's just what I need , my passenger side airbag light is above the radio and I wanted to move it. Just hope now I have the wiring in the overhead light. Do you have the part number for the overhead light?
