GM AC Delco E98 Key 2byte only??

[Jrom270]

Hi again,

so I wanted to read out another Opel E98 ECU (2016 Astra K) but I cant connect using IO Terminal.
I cant create a key because the SEED has only 4 characters -> B126. My key generator says the Seed is invalid.
I tried creating keys by entering B126000000, 000000B126 and some more variants (e.g less zeros), but keys that were generated all seem to be incorrect since I cannot connect to the ECU.

Is this 4 character Seed normal?
Can anyone help me retrieving the key?


here some ECU info:

(programming date is 2023 even though model year is 2016 because the car got a SW update)

Thanks

Contact with Andrius, is possible that ecu can't be read by io due sw update.....
