Horn Honk x3 After Locking

[jdomke1]

I’ve seen plenty of posts about trucks honking horns due to FOB left inside. Nothing with issue. About a month or two ago my truck started doing this. 2020 Ram 1500 Rebel. I press the door lock button as I’m getting out. The truck is completely off. The FOB is in my pocket. After closing the door it honks three times and the doors unlock. I can press lock on the FOB or the buttons on the handles and it locks. I only have two FOBs and the second is at home. Nothing happens on the instrument panel except the emergency blinkers flash three times. I’ve tried this with both FOBs at different times, ie no other FOBs on me, and it does the same. So, I suspect not the FOB. Looking for ideas.

Since you hit the door lock button before you have completely exited the vehicle, it probably sensed the fob was still inside when you hit lock button.

Sounds like an issue with the antenna in the rear door. Try locking the doors, and when you get out, toss the fob about 15’ away from the truck before you close the door (or walk the fob 15’ away and set it down, then go close the door). Does it still honk and auto unlock?
If so, it might be the rear antenna behind the license plate. Does the tailgate passively open ok? IOW, with the truck locked and fob in pocket, can you walk up to the tailgate and still open it?

That doesn’t matter. It only matters where the antennas sense the fob at the time the door is closed.

My truck honks whenever it wants. Lately I get 3 honks when I start my truck about once every other week, no idea why. Happened before I put a TazerDT in.
I think the truck gets lonely sometimes and just wants to give a good honk.

We are having this problem with our 2019 ram rebel. Exactly like you said. Husband locks door as he is getting out and when he shuts the door it unlocks and honks 3 times. If he sets his fob 15’ away then shuts the door no honks and stays locked. He also can NOT open the tail gate with fob in his pocket.

So we are having a problem with a rear antenna behind the license plate??? How do we fix this problem.

It makes sense. This all started after a new bed got put on his truck after a tree falling on it!

My 2025 i bought in June is doing the same thing. Is there something we can do ourselves to fix this or is this a dealer issue? I have not took plate off yet. I have had my truck battery be completely dead and the door locks twice did not work at all, fob would not work to lock unlock, buttons inside the truck did nothing, had to use key to physically unlock door. I took to dealer and they replaced the passenger door hadle due to some issue of truck staying awake and etc. Just got it back from dealer but the truck honking 3 times then unlocking doors has been ongoing since purchase. Sometimes it works fine but usually it does the 3 honk thing. Thanks for any tips etc.

Check the setting in Uconnect and turn it off?
