    Question Stolen Key replacement , Audi A4 2009


    I had 2 keys but, one of my Audi A4 keys (FOB) was stolen.

    So id like to:
    Erase the old key (or all keys) from the cars memory (to stop theft using the old stolen key)
    Re-program the key with a new code.

    Can I do this easily?

    Any information would be appreciated.

    Many thanks

    In a word, yes.......If you know how and have the equipment. You haven't said where you stand in that regard.

    You'll need VCDS or an equivalent to erase the keys. I've never needed to do it so somewhere I have the full procedure which I would follow to the letter. You'll be able to find the process with a bit of search engine work plus any additional comments.

    As a last resort, Audi or a good auto key shop will be able to do it for you.
