Just joined the club & this is my 1st post
I've got a 2005 (new shape) Focus Zetec with a fault.
The keyfob stopped operating the central locking but works ok using the key (locks & unlocks all doors & boot from drivers door).
I replaced keyfob battery & checked all fuses, all ok but still not working. Also no DTC's stored. I decided to disconnect the battery to see if it would reset & on re-connecting battery, all buttons work fine on the keyfob until the ignition is turned on then it ceases to work again. If the battery is disconnected & re-connected, same again - all working fine until ignition turned on.
Anyone got any ideas what may be causing this..?
