I had no many chances to check this tool:

BMW CAS IstaP done a few times. Sometimes first downgrade fail but second one always good. So no reason to worries.

If you done the update cas3 with latest software no chances to make the key via OBD need read eeprom no support latest update even for downgrade. I know this info is in manual but many cars suffer for that.

The unlock key option for BMW. Anybody tried it with success?
No much in manual about it.
Basically need to buy used key with the eeprom of CAS - that's how I understand it. Anyway tried many times newer works for me - can't detect transponder or file wrong or something...

Key frequency for smart key BMW only work if every time adjust antenna to 1 otherwise newer work. For any others make works perfect.

Audi a6 component protection on sound amplifier option missing. When go directly to sound module say "no component protection"

Make remote key option in transponder I don't know how to change language always getting like that;
