Hi group,
Just a question on the immobilizer on a ford fiesta 1.25lx 1999. Well I assume it has an immobilizer. I have a fiesta with no red programming key. My dad had a fiesta and I seem to remember he had a key which was all red. However I bought a used fiesta which only came with a black key that has a small red spot on the end.
So I assume I can't reprogram a new key should I need to. Or is this the red programming key I have and ford have just changed to marking it with a red dot?
My only concern is if for any reason the battery goes flat or the battery is disconnected does this mean the immobilizer has to be reprogrammed with the red key?
If so I'll just make sure I don't disconnect the battery for anything.
