Just to share with those who may struggle with this like I did.
1. You need cas and autohex and hextag
2. You need the cas connection cable
3. YOU NEED KEY SLOT and ribbon connection to cas
I did not have no 3 and program was asking me to switch on ignition!!
If you are in car then easy because you disconnect cas main plug, connect your autohex cable and use car key slot for ignition.
I can now make keys away from car at home with a key slot + ribbon and autohex. Superb.
