His website gives a UK address but no landline number, just mobile and overseas numbers. That would have told me all I needed to know..
Ok I have now replaced a few items that failed from being off the road for over a year most notably(expensively) the fuel tank which rusted through, I would suggest if yours is still good get it sealed internally because a new replacement is eye wateringly expensive and the second hand ones while only expensive tend to require work anyway. @chrisw has programmed a full set of keys, 2 black one red so I'm back to factory with functioning immobiliser!!
