Xhorse Key Tool Max Pro 2021+ GM Asks for 24-digit PIN Code?

 Problem:

I tried doing 2021 Buick envision, my Autel IM508 didn’t even read the system, My Xhorse vvdi key tool max pro was able to communicate with the system but asked me for 24 digit security code saying I must get it from 3rd party! The code obviously changes every time as well so it has to be done in one shot. How to get this code?

Solution:

Solution 1:

Xhorse cannot read these rolling codes.

Buy 24-digit security code from 3rd party.

There is a guy Ameer Hasan on facebook will provide this code.

Solution 2:

If all keys lost, you can do it with ACDelco SPS2 without rolling code.

Requires a J2534 adapter that supports CAN FD protocol.

Solution 3:

If add key, you can clone ID49 smart key using xhorse XM38 universal key.
