Hi guys, Im new to the forum and was hoping to get some help. I have just bought a 2000 mk2 mondeo zetec s, which has an issue with the central locking. My issue is that the car will lock all doors from drivers or passenger door, but only when you turn key twice to set alarm. Then it wont unlock all the doors, only the one with the key in. The fob doesnt work either. Its got me baffled so any help would be great, thanks.

is the key worn ??flat battery in remote or reprogramme the key fob again
