No Key Detected

[Hodag Ram]

I just have a 2025 Ram 1500. 3.0 L SST. I’ve been stranded numerous times now with the “no key detected “. I can remote start it with the key fob. Lock it, unlock it, shut it off. After about 20 minutes it just magically starts. The dealer has had it twice now and they’ve done what the service bulletins says. Still have the problem. Anyone else hear of this ?

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

My 2019 big horn does this even though the key fob is tucked into my belt or in my pocket. It does it a lot more since I moved everything over to the AJT design Key Fob. I have the chip swapped also, just doesn't pick it up when I get in to start it. Even if I auto start it sometimes it won't recognize it. I started tossing the keys into the console when I get in now to avoid the issue.

sounds like ya probably have the rear window leak and the electric hub behind the seats got wet and is causing problems..

There is a Star case for this, they need to contact engineering.

I took both fobs with me the last time it did it. Neither fob would work when pushing the start button.

My 2025 Lonestar has done this twice where the FOB is not detected with it happening last night after I remote started it while walking to my vehicle in an open parking lot. When I got inside everything else works like lock/unlock, yet touching the key to the button to start does not work. I basically tried locking the door and unlocking then opening the door and closing then locking and unlocking and it eventually detected. I am curious what the fix is for this, I imagine dealers are seething this with their loaners as well as new owners if we already have a thread opening here for these new models.

Mine is a Bighorn/Lonestar , it’s in the shop right now. They have no fix as of the end of day today. No software update. The dealer can’t duplicate it. The next time it happens I’m going to call the dealership and tell them to send a tech out to me.

Mine does this with the AJT case. I just have to open the case and reclosdnit then it's good for another week or two.

Just got a call from Stelantis customer service. They told me they have no fix for this at this time. Engineering is looking into it. Told me to try a different dealer to see if they have an answer. If there is no fix, how would a different dealer have an answer. I’ll be contacting Stelantis and complaining some more.

Someone already mentioned the RF Hub. They can fail intermittently and in different ways. Not necessarily catastrophic or even related to water intrusion. Mention that to them as a possible cause. Who knows what their response will be.

I've had this happen to me in my 2013, 2015 and in my 2022. In all cases, I discovered the FOB was in my left pants pocket and my cell phone was in the left cargo pocket covering the FOB. I recall the owner's manual discussing this.

Sitting on the roof of the parking garage in downtown Chicago pondering my choices right now with this exact problem.

Yesterday I traded in my turn key F150 for this beautiful truck. Now I’m stranded waiting for them to tow it.

Why are you stranded? If you can get into the truck, you just need to push the start button with the fob itself to start the truck

That will only work if the FOB battery is dead. Doesn't do anything if the RF Hub is failed.

I admit I don't know the full workings of the system, but wouldn't think the RF hub would be in consideration, when using the skim chip in the fob.

My understanding is the RF Hub controls all communication of the FOBs with the vehicle. When my RF Hub failed, touching the FOB to the start button did nothing.

Did nothing for sure. Had to have it towed.

Experienced this too. After finally getting a hold of the full manual as a download (my truck did not come with a paper manual), I found Key Fob mentioned a few times.

Page 17:
The key fob’s wireless signal may be blocked: if thekey fob is located next to a mobile phone, laptop, or other electronic device. This may result in poor performance.
If your vehicle is equipped with a Wireless Charging Pad, the key fob may not be detected if it is placed within 6 inches (15 cm) of the pad, reference page 71.
With the ignition in the ON position and the vehicle moving at 2 mph (4 km/h), all RKE commands are disabled.

Page 72:
To avoid interference with the key fob search, the wireless charging pad will stop charging when any door or liftgate is opened, even if the engine is running.

Page 73:
Do not place the key fob or any other type of metal/magnetized object inside the mobile phone housing or near the wireless charging pad.
CAUTION: The key fob should not be placed on the charging pad or within 6 inches (15 cm) of it. Doing so can cause excessive heat buildup and damage to the fob. Placing the fob in close proximity of the charging pad blocks the fob from being detected by the vehicle and prevents the vehicle from starting.

At this point I'm probably going to read the whole manual since there are definetly some gotcha's with this Ram.

Similar problem. Happened three different times in 5500 miles. I found that if I move my phone away from my fob, it starts. Don't know if that is correlation or causation.
