Cheers for the help so far but im still having issues.
I'v spoken to the guy that coded the keys, he says hes done plenty of ford keys and is confident that the keys are coded correctly. He said he could come back out but i'd be charged a £40 call out charge if it turned out not to be a problem with the keys.
So does any one know any way of testing the ignition ring? and if i was to fit a new/second hand one would it need coding?
Also is it only the keys, transponder ring or wiring that could cause the immobiliser issue/code? or is there anything else worth checking?
