Driver Side Passive Entry Stopped Working

[Canadianbear]

Good Day All,
First off I would like to say, though this is my first post, I have used this forum in the past to solve and get good advice on other topics. So thank you all for that and for any help you can offer me with this.

I woke up this morning and the passive entry (touch to unlock) on the driver's side would not unlock the truck. Pushed the button on the exterior of the handle and the doors still lock. I tried the passive unlock from the the front passenger side and it all works. The Lock/unlock and remote start all work from the FOB.

The issue only seems to be with the passive unlock on the front driver's handle.

I have a 2016 Ram 2500, Laramie.

Any help on where to start/diagnose would be greatly appreciated before I start buying parts.

Thank you,

Did you have heavy gloves on up there in Canada? Not sure if that would cause this, but an idea.

Nope. No gloves.
It wasn't too cold. it was about -7C that day.

I have a 2015 Laramie Longhorn and have the exact same issue. I tried to get a "rough" estimate from two dealers on a worse case scenario on getting this fixed and neither one would even talk to me about it. My only option is to let them charge me @$200 to tell me what is wrong and then I can decide if I want to go any further. Unfortunately, they keep the $200 if I decide it is not worth spending that amount of money to fix. The "passive entry" works fine on the passenger door, but just not the driver's side. What did you end up doing for your situation or are you still waiting like myself?

I had actually posted this to another response, but it was meant to go to you. This is actually only my third response on this forum as well.

When Dave is locked out of the ship from space, he calmly says, “Open the pod bay doors, HAL.” After a cryptic pause, HAL responds, “I'm sorry Dave, I'm afraid I can't do that,”

Kidding aside, my 2014 1500 Laramie requires that my fingers make contact with the "inside" of the exterior door handles.
In other words, I have to actually wrap my fingers around the handle. Same for both doors.

I'm betting this is not the issue you are having, but it took a while before I discovered this!
HTH, good luck.

First, let me say I work on all makes & models so I might be mixed up with Ferd.
I believe if the battery sense starts detecting a low or failing battery, the BCM will start shutting down certain functions. Like I said maybe I'm confusing it with Superduties but it will start with Driverside but allow Passenger side to still work. Usually a reset of the battery monitor will clear it so by disconnecting the battery (& replacing if necessary) will cure it and all will work again.
Has anyone tried that or experienced it?

My suggestion is if you have not, change the battery in the fob. I had my passive entry not work one day, next think I know getting fob not present when it was in truck. Changed battery, passive entry started working .

My suggestion

But was your passenger side still functioning when the driver side wasn't
is the question?

Howdy,

Was there a fix?

I have a 2013 and the passive lock and unlock on the passenger side does not work with either FOB. Driver's side works fine. I took the passenger door panel off and disconnected and reconnected all wire connections and that didn't change anything. I disconnected both battery positive cables and drained the capacitors by shorting one of the cables (I have to do this regularly to get the HVAC system to come back to life) and that did not help. Changed the battery in the FOB although I don't think this matters since the passive entry operates on RFID/transponder but anyway, that did not help. I sprayed the passenger door handle with water (i.e. washing the truck) and that did not help. I used compressed air to blow out the passenger door handle and that did not help. I charged the truck batteries and even attempted to use the passenger door handle while the charger was putting out around 15v and that did not work.

Thanks

Just maybe, the door handle sense strip is kaput. Can't imagine spraying with HP water spray will fix anything electrical in nature.
