e39 remote central locking issue

[kildangan_kid]

It could be interference in the location where you locked the car. Try to lock/unlock in another location.

Tried it at home and at work, still nothing..

Try resetting the key. They need redoing occasionally

Thought that myself but only got a brand new key last June. Two other fobs don't work either

I checked the fuse and it was fine. Put in a new one anyway still no difference..
