How to bypass GM 24-digit body module BCM security verification code for 2021- new GM CAN FD models?

Autel CANNOT do the new GM immo system. the ONLY aftermarket tools that can do it are obdstar, xtool and autopropad.

Obdii365.com here provides top 4 tools to bypass new GM pin code.

1). Xtool tools

The $500 or lessXtool D7,D8,D9,D9 Procan do CanFD, even 2023. (Stand alone the D8 & D9 ) (with CanFD the D7).X100 PAD3, A80,A80 Prowill also do this.

D7 does this fine. The D7 didn’t have the CAN FD so you had to get a different cable and useXtool 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 D . 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.

Follow CAN FD Models are supported by Xtool, keep updating

2). OBDSTAR & CAN FD Adapter

OBDSTAR X300 DP Plus/X300 Pro4andCAN FD adapterwill program key for new GMs without 24-digit pin code. OBDstar fantastic for US made cars especially helpful with newer models.

The GM adapter is compatible with the following new GM models:

V33.45 IMMO software adds Cadillac Escalade 2021-2022, Chevrolet Corvette 2021-2022, GMC Canyon 2020-2022 proximity (with CAN FD Adapter).

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

Can be done with sps2, no need code or nastf. Only subscription.

If you have a laptop and J2534 passthru device (MDI2, Autel Jbox,VXDIAGetc) you can do it from acdelcotds through Techline Connect.
