Timpsons in Dartford came up trumps for £30, coded & cut. Although the first time he coded it correctly, but then cut a different key (a spare one I have, but no idea what it's for). Anyway they changed it hassle free for me and checked the other spare which is also coded. So someone I have a spare key with immobiliser code for your car. New key is really stiff, but it is only a spare afterall, so not an issue.
Beadles VW, were not very helpful to be honest and don't cut key apparently.
