    Not sure if this will help but when i replaced the battery all i did was unlock the car with the key then start the engine. after that it managed to work. Hope it works for you.

    Paste it into notepad, then copy and paste it into ASN - this will get rid of the formatting markup.

    Andy there is a small LED on the key which flashes when any of the function buttons are pressed The one on the faulty key flashes just the same as the one My wife has . But I just cant get it to lock or unlock the doors since fitting the new battery Ive changed the battery again in case I had fitted a faulty one But as yet No good ! Audi want £60 to do the job !
    Im wondering if investing in Vag Com So I can sort iot out as Id rather put 60 quid towards that than pay it to Audi for a 2 minute job !

    Genuinly appreciate Your help ........................................

    just found this mate from another thread, worth a try


    Right everyone cheers for all your replys , was just about to go to the stealers when i thought id have a quick look through my manual, it tells you how to synchronize the key fob! It was easy press unlock/lock on the fob then within 30 secs put the key in the lock and either unlock or lock the car and it will re-synchrozine its self!
    Cant believe the stealer wanted £80 to do that! Robbing Bast**ds
    Still got to fork out £180 for a spare key though
    Cheeers for all the info again
