Tried doing an e90 yesterday customer only has one key but cas has comfort access
I found cas unit had 4 enabled comfort keys I tried but couldn't find a way to delete any old comfort keys with auto hex but couldn't find how there's only a disable key option, how do I delete and clear cas key position with auto hex to only have 2 comfort access keys

Appreciate your input

go to key learning option 1 you can delete unused keys.

Thanks
