Hello Krazzz,
Are you sure it said "ignition switch", as I have never seen nor heard of that when I had my 04, nor in my 05 W12, but I have seen the "Key not in vehicle" warning, where did you get the picture you posted referencing "ignition switch" ?

I hadn't noticed it before but I do have some wetness on the drivers side. We had some torrential rain a week or so ago and I was parked in a very steep driveway. Maybe this combination overwhelmed the drains? Is there a diagram that shows which modules are under there?

I Don't Trust AUDI Dealers Either, but
...they hold the "keys" to the kingdom when it comes to the start authorization system. Please see attached PDF for module location, etc.

...has nothing to do with the key failing to work in the ignition. When you use your key this way, an inductive circuit in in the ignition switch excites the RFID chip in the keyfob and interrogates the key for authorization to start the car. This is a feature along with the mechanical lock under the drivers side external door handle allowing entry the car and starting when the keyfob battery is dead or the remote transmitter is broken. To test this, take the battery out of your remote and try it in the ignition!
Hate to say it, but this is a tow to the dealer situation.

Yes I know all about the glass chip in the keyfob, as that is what his Audi key has, my point was to check the KF battery as now the remote was no longer functioning for the locking or un-locking of the doors, hence my comma, then on to the info on the wetness as to Louis' link, but since you said to try it with the battery removed, which I have done and posted results on here before, I just went out and shot this picture, and here is what I get if I take the battery out of my 05 w12's key fob.....

See the link to the thread for information and pictures of the KESSY/IMMO module location, it is under the drivers side front seat, you can see the pictures I posted of Kam's vehicle showing the KESSY/IMMO module missing from his car, but you can see the harness at the area where it should be, I would lift the carpet in that area just to see how wet it is under there, if the KESSY is in fact wet, disconnect the battery and remove said KESSY, open it up and dry it out with a blow dryer, hopefully it will work after dried, if not, then a used unit of the same exact part number will be needed an also need to be programmed/cloned, more on that if it comes to that.
