There are some tools that will bypass 2021- GM CAN FD models 24-digit body module security verification code.
1). Xtool tools
The $500 or less Xtool D7, D8, D9, D9 Pro can do CanFD, even 2023. (Stand alone the D8 & D9 ) (with CanFD the D7). X100 PAD3, A80, A80 Pro will also do this.
D7 does this fine. The D7 didn’t have the CAN FD so you had to get a different cable and use Xtool CAN FD adapter.
there’s no provision to get the pin from General Motors. I’d get a Xtool programmer (I’ve used D7 and D8). The D8 is a bit easier to get going but I’d also consider a D7s as it says it has Can-Fd built in. I did 3 of these today with my D8. Check It out, there was a small issue but it ended up working fine.

Example:
OBDSTAR Program 2021 GMC YUKON Prox All Keys Lost via CAN FD Adapter
3). AutoPro PAD Basic and Full
Yes Basic, (despite what the CanFD tools sales website says) can do CANFD PROTOCOLS with the CANFD ADAPTER.
app basic with regular cord then canfd adaptor to Obd.
Must have good cellular/internet connection. We had trouble pulling the pin using mifi Internet boxed but works? fine on cellular hotspot (we all have iPhones with the “Maximum Compatibility” option selected).
I purchased the Xtool CanFD Adapter and together with the Xtool Auto ProPad Basic I was able to program a 2021 Cadillac CT5 today. Same Process as usual GM vehicles with the CanFD adapter.
4). SPS2
J2534 device (MDI2, VXDIAG etc) and SPS2 will program keys for new GMs without pin code.
