hi everyone. Ive got a 2008 focus mk2.5 1.6 petrol. the remote fob has stopped working and now i have just changed the battery and it hasnt made a difference at all. Still the remote does not work and i dont want to be ripped off at the dealers.

I have read on the net the key needs reprogramming. The spare has no remote. So do i just do the one main key? I dont want to muck around with the immobiliser.

Thanks for any help.
