So I have a 15 Durango I noticed none of the buttons work (they did yesterday) but if I grab the handle it unlocks (pushing the button on the door handle will lock the doors also). Also starts without trouble. I scanned with AlphaObd and no codes. Any clue? Batteries are new I'm the FOBs I tried that first

 

You have multiple fobs with the same issue?

 

Yes two. I though it might have been the RFH (Radio Frequency Hub) but that wouldnt explain why the passive entry works (the touch handles)

 

I wouldn't necessarily rule out the RF Hub just because the passive entry works. My girlfriend's Charger remote keyless still works, but the Bluetooth for the radio does not. Everything associated with the RF Hub other than the Bluetooth seems to be fine. If I unplug the RF Hub for several seconds, then plug it back it, the BT works for some amount of time before failing again. I opened the RF Hub hoping to find a bad solder joint or electrolytic capacitor with high ESR, but found nothing obviously bad. I even reflowed a few questionable solder joints to no avail.

Some parts stores have a display for testing key fobs for signal. Usually it's part of a countertop display with a variety of common fob batteries. You could try to confirm that both of your fobs are transmitting. I think AlfaOBD also has a datastream mode where you can monitor for the RF Hub receiving a fob key press. If the Hub never reports an RF signal, then you might check antenna connections. I seem to recall seeing a few folks who had antennas that came disconnected at the base of the liftgate. I don't recall their symptoms though, but it would seem worth checking into.

Here's the thread I was referring to re: the antenna connection in the rear, and the symptoms for at least one user seem consistent with what you're experiencing.

Thanks for the info Rod! I will check into this

 

Update: Did a reflash on the RF Hub with my witech and it now works

 

This intrigues me. I hope you don't mind that I'm going to send you a Private Message to see if I can get a few more details on this.
