Thanks Aero, That’s really interesting and gives a great insight into the system and how it works. Unfortunately there is no reference to a blinking code/key symbol on the dash as I have. Chrisw is on the case though, so I’m sure it will soon be sorted
they can make new keys and also Dash repairs and much more https://www.carmo.nl/index.php?main_page=sleutels_verloren_aanmelden&language=en https://www.carmo.nl/index.php?main_page=index&cPath=493_498_3038_4751
