    Hi,

    My friend owns a 2003 E39 530d Estate and his key fob has stopped working.

    It was intermittent for a couple of weeks but eventually stopped working completely and he now has to lock the car using the key.

    He has tried using his spare key fob but it doesnt work either.

    We have checked the fuse in the boot for the central locking but its fine.

    I believe the key fob is meant to charge from the ignition is this correct? The key spends most if its life in the ignition so theres no chance it could have gone flat from lack of use.

    If anyone has any ideas on what the problem could be it would be very much appreciated.

    First thing to do will be to get the key tested using a fob tester, if all is fine then the body control module needs delving into with diagnostic equipment. A BMW indy garage can do this.

    Thanks Ronnie much appreciated, he is going to take it in to a BMW specialist to have it checked out.

    Its weird because the final stage resistor went at nearly the same time as the fob stopped working but he has replaced this himself.

    What exactly is the body control unit?

    Thanks again!

    EDIT: Ive just found out that he tried it yesterday and it unlocked the car remotely but hasnt worked again since!
