    How to generate GM Seed Key using GM's DPS

    In this tutorial I demonstrate how to find the seed key for the GM E59 ECM module which uses the 2 byte security seed key.

    Tools you will need are.

     

    Step 1

    Open the utility file in the hex editor and look for the first code: 27. 27 is the GM's operational code for security access.

    Right beside the 27 op code, you will see the security algorithm code, in this example the security algorithm code for the E59 ECM module is: E7. Right beside the security algorithm code you will see the security table code. In this example the security table code is: 00

    See the below attached photo example for the needed security algorithm and security table code in the hex editor.

    Step 2

    Open dps, click Get Controller Info. Then select the security table: 00 as was stated in the hex editors modules utility file. Type the security algorithm code: E7 as was stated in the hex editors modules utility file. Click "Read Info" DPs will then generate the seed key for the module.

    See the below attached photo example for typing in the security algorithm and security table code into DPS.

    Leave a feedback and let us know if this method works for 5 byte and 32 byte GM seed key vehicles.

    Thanks, that’s the goal, the more information we share the faster we can figure out new things and hopefully master it all someday 😀

    Hello Mr. Troy I did this tutorial and finished successfully.

    But I dont know for what and when I will use it (GM Seed Key )

    could you please explain.

    The seed key is useful for folks who want to manually send commands to the locked modules via can bus. 
    it’s not really useful for dps as dps automatically generates it.
