Using a later model key fob on the A2

If you have the right type of tv catcher USB dongle, you can check if the key is transmitting anything with SDR. Let me get back and tell you more about this tomorrow.
 
Hi yes I do have the log in code and have some chips arriving today only problem is the eBay key I was going for has been ended early so I'm on the look out again for one

So, what is SDR (Software defined radio)? It's a radio tuner that you hook up to your computer. Someone discovered that a certain chip in these radios can be controlled via computer and the output can be seen as a graphic.
I got me one of these from eBay http://www.ebay.com/itm/Software-Ra...-Stick-GT56-/181266731485?hash=item2a3456d1dd
I use it together with a free program called SDR sharp. The antenna is pretty weak and I the thing that I receive best is FM radio. But, perhaps it could be used to determine whether a key fob is actually transmitting. Since we know the frequency, it can probably be seen in the graphic. I don't have the dongle where I live now, and I don't have a radio key fob. But the dongle is quite cheap, so perhaps someone wants to buy one and see if it can be used for this.
 
Using a later model key fob on the A2 - expert help needed please

Hi Steve so I got my key today and new blade but have a question as I recalled you said you removed the old immo chip and replaced it but I couldn't see were this is on the new style key Also were did u place the new immo chip as it is abit big I tried on top half but then buttons don't work to well was thinking bottom half under the circuit board but not sure and don't want to damage the board when closing it all back?
 
Hi
on the new key near the blade and under the circuit board you will see a light grey area of soft plastic.
The chip is in there, just cut it open and remove the old chip and slide in the new one. It should hold it ok but if not, then just tape it down in there.

Also
you say that the immo chip is a bit big?
it should not be big it should be a very thin and small tube.

But i guess you are merely saying that it is too big to sit on the circuit board.
Which may well be the case.

You need to remove the circuit board on the new key to get to the grey plastic protector of the old chip anyway.
But you will find it reluctant to come off.
You can get it loose easy enough but the last bit is tricky.

You have to ease it out and it WILL come off but dont bend or scratch the circuit board.
Use a piece of stiff plastic or similar to ease it off evenly.

Thanks allot for that Steve I actually got my old chip out already it dislodged itself when I tried to open the old key not realising there was a screw under the Audi emblem lol
 
Ah, yes, the hidden screw on the old style key fob.

Sorry I didn't mention that, I use a new chip and so didn't have to strip the old key down at all.

OK,

These are not everyone's cup of tea, but for less than £3 they are worth trying.

They fit the new shape key and it means that you can colour code it to your car.

It does make the key fob a tad bulkier, but I also make s=it almost impossible to have the buttons pressed by accident when it is in your pocket. They come in a range of colours (Including yellow? Mike?) LOL

As I say £3 is not bad.

The plain new shape key fob looks good enough "in the raw" but it is always worth sharing options, good or bad?

Just tried the 8E0 837 220Q later style remote, and that works perfectly with the AF CCCU too. The buttons seem to be the "hard touch" style, so take a lot longer to look manky...

Can you tell me what MHz is this and what 'chip', (ID48 or 8E, etc..) ? 🤔

The Audi markings say 433MHz, but you'll be needing a new ID48 transponder chip anyway. There are some very good looking after-market complete keys representing good value, such as this one I found on eBay: Audi Remote Car Key Fob ID48, 433Mhz - 8E0 837 220 Q

Although that is a much more economical way to achieve the newer key, I still prefer refurbishing an original Audi fob because it has better dust and water seals than any of the after market versions I have yet seen. It will work out a lot more expensive due to having to get a new
blade and have it cut & fitted, and a new ID48 transponder chip (good condition used Audi Key £25ish, blade £7, cutting £18, ID48 £3.50).

Evening Mark,

That’s another great find. I can also confirm that the 8E0 837 220 E remote fob also works with the AF revision CCCU as mentioned on the Project OEM thread at Post #3:

Project OEM (2002 Azure Blue TDI AMF)

Afternoon All, As promise recently after @A2Steve rightly pointed out that there is a lack of project threads being published whilst we know there is probably quite a lot going on with our Aluminium Friends, as some of us find ourselves having a little more time on our hands. I’m certainly one...
www.a2oc.net

This looks to expand the list of Steve’s @Birchall original findings out to 3 possibilities for the addition of the later style remote fob.

Kind regards,

Tom
