remember that any key will need recoding to the car which will cost and needs info from audi. So dont pay too much on ebay, some sellers claim its easy to code , but they mean the remote locking not the immobilizer.

On an A4 it cost me £100 to get a key and coding from an auto locksmith.

I've just returned from the dealers this morning. Bought a key fob for my 02 A4 of ebay. Made sure the fob had the same code number i.e. 8Z0.... Bought a replacement blade also from ebay (using a digital photo as the pattern).
As I only had 1 key thought it best to have it programed at Audi's. Turned out that the top part of the key has a 'chip' in it that is linked to the year / type of alarm.

£43 later they can't program the key as its the wrong type and I've had to order the specific type of blade / top of fob that has the right 'chip' in it.

14 day wait and another £100 for the part and programing!!!!

Beware of Shortcuts!

It is a ******, but I think that has been said more than a few times on here already, but just like everything else in life we always find out when it is too late! /ubbthreads/images/graemlins/frown.gif

Welcome to the forum anyway mate, stick around!

that sounds a bit odd though - I would expect a different part number if the key fob was different. Else how is the dealer going to get the correct one ? Is the final letter different ?
