    It may just be a battery in the key fob that needs replacing. You should be able to do it yourself.

    The battery in the keyfob is only for the central locking rather than the immobiliser. I'll assume that the keyfob opened the door, but when the car was started it cut out almost straight away.

    The immobiliser transponder in the key may have lost it's coding and it may be a simple matter of having the key reprogrammed. It could of course be faulty, in which case a replacement key will be required.

    You should try and prove that the key is faulty. Check a few times to be sure it fails to start with the suspect one. Remember to leave a few mins between attempts for the immo to reset. The instrument clusters on these can be faulty and give the same symptoms. It is possible to repair these rather than replace.

    Good advice - keep using the suspect key (keeping the spare with you) this way you'll know if the suspect key is faulty. It could be the cluster as Mr.D points out. It could also be the read coil which gave trouble on lots of VWs. Have a diagnostic machine hooked up if you can - it should help narrow it down to a specific item.
