Had the AA out today who says that the immobiliser is no longer recognising the key.
Tried several tests and says needs to have the immobilser/key re programmed.
Which is what was mentioned on the page i pointed you to, it said --
Immobilizer warning light on Ford B-max: Neiman or key issue:
We will have to start by checking, if the key
is still operational. Indeed, in the event that it has undergone an impact,
it is likely that the latter is deformed
. Therefore, we can assume that it no longer manages to communicate
with the vehicle thanks to the transponder
Or even just that she's discharged.
So do the verification using the second key
of your vehicle, in case it works, then you may have identified the source
of your dysfunction. If you don't have the second key, try replace
yourself the battery
