Button functions on both Keys not working Still able to start truck

[DreadSpectre]

I have a 21 Ram 1500 Leramie 4x4 with Ram Air suspension. Suddenly both keys that worked perfectly before will no longer signal the truck to Lock, Unlock, remote start, Lower tailgate, lower suspension, or panic. While all buttons no longer work, both keys will allow me to unlock the door when i am in proximity and touch the handle and will start the truck.

Already tried:
replaced both batteries in fobs
even right next to the truck these functions will not work
Checked Fuse F24. The book says it should be a 15a blue fuse but it is actually a yellow 20a. I bought this car brand new and I know that there has never been anyone in the fuse box before.

Any help on this one would be appreciated. I will be checking all fuses today.

Has anyone had issues with the rf receiver not working?

Did you ever figure this out.. Exact same issue with my 20 Bighorn

OK.. I found my "fix". I'm guessing that you checked the fuse box under the hood. A 20 Amp fuse in F24 is correct. It's for the tcm. The F24 that you need to pull is right under the steering column. The F24 in that location is for the RF hub. When that fuse is pulled or blown, your dash will be dead and not detect a key at all. I pulled mine for a few minutes to check the fuse.. It was good but I noticed it killed the dash. Once I put it back in, everything reset and worked perfectly. Guess it just needed to reset itself. So happy to have my remote lock/unlock again.

Wish your"fix" worked for me.
There are no fuses that I can see under my steering column. '12 Big Horn
I did however pull my fuse for the WIN from under the hood. M27 a 10 amp fuse. It disabled the WIN when I pulled it. Putting it back in did not however help.
On to the next.
