It is worth checking if Craig can now do pre '98 S8's etc as he was unable to code the key to the immob on mine.
Although he may be interested in doing what I did and digging out a functioning immob chip from an old key and inserting it in the new key (after removing the new immob chip of course). Worked very well for me on my 1998 S8 and I do love the Bentley key I bought from Craig
Quality is fantastic
