Using ISTA-P/ISTA-D did not reveal options for me to get the key working but I did find how to assign the different key slots and personalization options in these menus. So if I can get the key to register then I can probably get the CAS personalization options to work with the different keys I hope to have.
I have been hunting for hardware options to deal with the key and your recommendation of the CGDI is another option. Thank you for that.
I will be doing this myself rather than paying someone else to do the work. I need more than 1 key and the dealer has already quoted me something like $550 for 1 key. That kind of money puts me close to buying the equipment I need to do the work myself.
I live pretty far away from civilization and access to a dealership, or indy shops with the ability to do this work. I have a self-sufficiency mindset and I figure if I can take care of this myself I will be better off.

Your key personalization should work perfectly once the new key is added in the CAS. Do be aware that newer CAS firmwares must be downgraded to work with those aftermarket programmers. My 2007 E70 and my dad's 2013 E70 both require that downgrade which I have yet to attempt; my understanding is that it should only be done with a proper power supply attached to the vehicle although CGDI does have the downgrade capability included. There are some articles out there on how to modify old HP server power supplies to work for car programming and I'm going to try it out. Also, not to scare you, the E70 LCI is rather unique in that it's the only E-series vehicle that came with the 8HP transmission. Unfortunately, both the 6HP in the older E70s and the 8HP in the LCI have a security code (ISN) that the CAS verifies. CGDI can reset read/reset the ISN in the 6HP but is unable to work with the 8HP as far as I know... which means if you were to totally brick your CAS, retrofitting a replacement may get expensive.
Read this from user DNK76 on another forum:

Read CAS with the VVDI, EEPROM and FLASH programmer,
then you can lower the software version anyway,
the most important with CGDI is a voltage higher than 13.8V
I noticed how the voltage within 12V is flash lowering version fails.
Without a copy of the software (eeprom and flash) do not start the downgrade in e70 / e71

With a backup, a bricked CAS can be restored.

Agree. Always better to brick it yourself.....

Been there, done that (not with CGDI ...yet).
