Don't go anywhere near a generic "key specialist" that messes with the BECM. Only Marty & a few others on here have the correct BECM tools. In any case it still requires genuine P38 key fobs.
If the BECM is original then the main stealer should be able to order the correct key. If they cannot then find a better LR dealer. If the BECM has been changed then you need Marty or the other chaps to find the correct key details for you.
