2015 2500, I need some help

[RCMEDIC]

My 2015 Ram 2500 6.7 Turbo diesel has been awesome. With about 120k miles on it, I returned home from a short 30 mile trip into town. Shut the truck down got out and attempted to lock the doors with my key fob as usual. The doors did not lock. Tried all of the function buttons. No Panic, No lock/unlock and no remote start. Stick the fob into the ignition and the truck starts right up and runs fine. Repeat to process noted above with same result. Try my other three key fobs. Same result with two out of three and one fob just totally dead to include not starting the truck. (new battery in the dead fob changes nothing). Trouble shooting so far nets zero obvious leads. I have several tried several OBDII readers and AlfaOBD as well. I am at a loss. Any feedback or suggestions appreciated.

My local mobile locksmith knows more about these systems than the local dealer does. He has a couple of cool tools to work on them and he replaces and rebuilds the ignition portion as well. Might be a place to start, guessing someone like that could tell you if it is an issue with the fobs or the receiver in the truck. Whenever I had a fob issue, it was the opposite of yours. Remote worked for lock unlock but wouldn't start the truck.
