I wrote my new key to Slot 8 as I will never go to the dealer for a key.
Thanks for this great DIY!

Just to check, if anyone adds any non original key to any slot, the dealer will not be able to create a key for the car? What if the dealer creates a key for slot 4..7 in your example, where you coded to slot 8?

What if I get a backup of the CAS eprom and flash using e.g. R270+ or VVDI prog?
