Replacing CAS

[Gee_115]

Hello all, I am about to undertake a mission to replace my CAS with a new one. I currently have an OPS unit with DIS 57 and SSS 41. I also have a brand new key from dealer. I am not sure how to go about this mission since the CAS and key are virgin. I also have to change VIN in DME.

Do i hook up the CAS then initialize the key before encode/programming?

If I have to encode/program CAS before key how do you go about this because from what I understand the ignition needs to be on to program?

How do I resync CAS and DME? Which tool is easiest, DIS, progman, or INPA?

I apologize for so many questions.
Any help on how to go about this DIY would be greatly appreciated. Thanks.

Sorry but you cannot change the vin in a DME using the BMW. Tools unless it has never been used and is "blank"

Actually you can use WinKfp to change VIN in a used DME.
