    Where to buy new Fob?

    hi guys,
    I need a new key fob for my car. where is the best place to purchase one? looked on ebay but can't seem to get my part number.

    cheers

    p.s it needs to be a 3 button fob.

    As long as you have the same style it will work, but you will need VAG COM to code it up.

    i currently have one which i brought from ebay but the code is 4D0.837.231K (not A)
    this will not code to the car. could it be a faulty fob?

    I think that the '4D0 837 231 K' key is for year 2000+ A6/S6/RS6 & TT's.

    think you might be right as it did say A6/TT in small print under the part number.

    looks like it's going back on ebay until i find the right one.

    Thanks

    not if youve got 2 keys
    turn ign on with first key
    close door and lock manually with 2nd key, press unlock button wait 6 secs press unlock again and its done
    swap keys and repeat but press unlock twice then wait and press again
