Here is what I changed and it works great.
Walk Away Lock (2024 only) - locks the vehicle when you walk away. No audible when walk away.

Do not tun off in Settings or will break feature, but if you do break it then just go back in and set with FORScan.
Reset APIM. Clear DTC after you are done (I clear before I start and after I am done.)
Now for me I had to completely power down the truck, get out, lock it and then get back in and start up, and then shut down, get out and walk away for it to work. Some combination of that.
If all that fails, then go into FORScan and verify the changes took.
