Ini,
Thanks for both of your replies.

All the earlier type modern Audi keys have a Megamos type 13 transponder capsule inside them, it looks like a tiny glass pill with a miniature copper coil/circuit inside it. Is this inside the actual key?? or is it in the Fob Transmitter. "id 13, SKC, 'rolling code' crypto, RF pump, 'static' immob capsule " What? I'm in deep waters aren't I?

I don't know why this is all so confusing to me. I'm actually quite mechanically inclined... head gaskets, timing belts, rear ends, struts, ball joints, gauges and clusters... Electronics! There's the difference

I've done so much searching for answers to this question that apparently many others have as well and the only people who really have the "simple answer" want to be paid for that knowledge. i.e E-Bay etc...

Ini, don't get me wrong, you're the only one talking to me and I appreciate it. I feel that I am on a noble quest, dreaming the impossible dream... If we ever come to an actual conclusion, we could put it in the FAQs or I could post it on one of my web pages...

For the sake of simplicity, let's ONLY refer to Non Flip Remote Entry Fobs (FCC MZ2 410 816 4)
and the early Flip Keys with built in remote (FCC MZ2 410 816 6 4) Note the extra 6

My next question is: Does the Steel Key, Fob Transmitter or Car actually get re-programmed when switching to a new remote keyless entry? I would have to guess that it's actually the car that is being reprogrammed.

For instance: I install an automatic garage door opener... I can set dip switches in both the opener and the remote. The communication between the two devices is only one way. The remote talks to the opener, the opener does not talk back to the remote.

Maybe I'm wrong, but it would make more sense (to me) that the car is the device actually being reprogrammed, because the Fob Transmitter is the only thing sending out a signal and the nowhere have I read anything about opening up the F.T. and performing any work in there.

For Instance: When reprogramming... A key is placed in the ignition in the first position and, in some cases, as with a "flip key", the flip key is placed in the door lock and then all the magic happens with the pressing of buttons. (see below) Putting the the keys in the proper places and settings prepares the system (car's computer) for reprogramming. I would think that this holds true for the older "NON FLIP" FOB ONLY Transmitter types as well. Yes? It also seems to make sense with the way the Seats and Mirrors are programmed to a remote signal as well. The seat memory is changed, not the remote transmitter.

What I found in another Audi Forum: -

You need two keys to program the unit, one is left in the ignition while it is on, the other is then used to manually lock the driver's door to put it in "program" mode. Then you press the open button on the new keyfob in one-second increments (1 time = remote #1, 2 times = remote #2, etc. 5 times = deletes all remotes) This doesn't have anything to do with the seat memory function in this car. Then wait six seconds and press unlock once again. The new remote should work.

Sooo.. when I lock the door, does it make any difference if I leave the key in or take it out? Hmmmmm...

So, in short. WHAT is actually being reprogrammed?
Steel Key?
Transmitter?
Car Computer?
D) All or some of the above?

Thanks!!!!

And for my next trick I will try to upload an attachment! AND it's a PDF! woo hoo!

Cheers!
