No Key Detected

[PT1911]

And just to reiterate from a previous post of mine, this is NOT just a 2025 issue, my 2024 had it happen multiple times. (I have not had it happen yet with my 2025)

My 2025 Ram 1500 had this issue for the first time yesterday. It's currently in for service after having it towed. Would not unlock the truck, used the key in the fob which set off the alarm. Tried touching it to the start button and got "key fob not detected". No way to shut off the alarm other than wait it out. Had my wife bring my spare key, which also did nothing. Tried disconnecting the battery which also did not stop the alarm. Most frustrating few hours of my life sitting in the Walmart parking lot trying to figure out what to do and waiting for the tow truck. I'll try to remember to update this thread if there's a fix, but I have lost all confidence in this truck and that it wont strand me again.

This is a serious issue that has been going on for WAY too long! RAM really needs to step up and get this figured out!

These symptoms are almost certainly the RF Hub failure. When the hub fails and you open the door with the key blade the alarm will sound. It thinks you are breaking in because all comms with your key fob is lost. That's why the spare fob acted the same way. Funny but I was able to stop the alarm by disconnecting the battery. Where was the alarm getting its power without the battery? You may find out the failure was caused by water intrusion through the back window as others have mentioned. This is a chronic problem with our trucks from the factory. It's ridiculous. It is possible that the RF Hub failed naturally of course. I am interested to know what they find with yours.

I have not heard of that but if it happens again push the start/stop button with the fob and see if it starts .

Mine did it today and did the push key fob into the start/stop and still didn't work

That’s what the dealer said to do and that gives them more information about what could be wrong .
