I've been following this thread with interest, and am more than a bit puzzled by the outcome.
According to the Ford blurb these keys are supposed to have an inbuilt rolling transponder code (chip) facility, so are a teeny bit 'intelligent'. Otherwise what's all this business about reprogramming them from the ignition/immobiliser circuit by rotating the key nine or so times in the ignition when you obtain an alien key?
Have I got this wrong? Is it actually the remote key fob that's got the chip in it? If so, do the fob and key talk to each other each time you try to start up? What's actually going on here?
If your man just got a duplicate key cut by his local locksmith which worked, then it sounds like the Connect bonnet lock doesn't need a properly chipped key at all. If so, it's purely mechanical. It can be opened with any (Connect-type) key, or even maybe any other Ford key for all we know
I had a SWB 220 Hallmark before my present LWB 230, which came with a duplicate key & fob as part of the deal. I couldn't see any physical difference at all between the end of the key for either van, and told the dealer I wanted a freebie spare set for my new van. I got the same duplicate key set back in under a minute reprogrammed to my 230. If I'd tried this manoeuvre meself I'd have made a tit of it.
So what did they do or is all this black magic? Anybody got an explanation?
