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.
