Hi, one of my keys is no longer working. A warning flashes up saying 'anti theft system faulty' when I try to use it. The other key is fine and works no issues. I suspect the key isn't turning the immobiliser off. I've changed the battery in the key but this hasn't worked. Obviously I might just need a new key, but since I use this key very rarely I wonder if its maybe gone flat and I've not changed the battery in time? If so presumably now I've changed the battery I could somehow reprogramme the key? Anyone know if this doable - or is this a dealership situation. thanks. Dan

If you’ve changed the battery you probably need to reinitialise the key.
From the manual:
“Reinitialisation
- Switch off the ignition.
- Turn the key to position 2 (Ignition).
- Press the closed padlock immediately for a few seconds.
- Switch off the ignition and remove the key from the ignition switch.
- The remote control is fully operational again. “ -
