Audi A6 PCF7945AC original key from used key

[badaca]

Hello, I want to reuse an original Audi key for a 2016 A6 4G. The original is a 8K0959754D on a 233.453.211-02 board . The used one is a 4G0959754K on a 233.453.111-06 board. I made virgin from the used one, wrote CS with Smok and tried to adapt online. No succes. I could try to do it with smok to the end, but smok offers no support and if BCM doesn't wake up I am in trouble. My question is, why is the programming procedure failing? Does it check for part number or other config in the key (because PN of the keys are different as the original and the used one use different PCB and software for them is different)? If I buy an used 8K0959754D and follow the same path will it work? Thank you
