Only, Xtool, Autopropad, OBDSTAR and SPS2 will program new GM CAN FD proximity smart keys bypass pin code.
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.
