Hey guys. Anyone having problems with there key fob. I keep getting a key fob not detected on both sets of fobs. Called the dealer they say to put fob in the centre console cup holders to reset fob, but when I do my keyless entry stop and I can’t lock the truck. And the fob won’t open or lock the truck. Any thoughts.

Had something similar happen on my 2011 Cts coupe within a couple hundred miles of driving it.  Key fobs were real weak, to the point that I'd have to put them in the Fob slot.  And when I'd press the door popper from the outside (no door handles on the coupes) it would pop the trunk.  

 

They replaced the computer for the keyless entry and I never had another problem for over 210k miles. Took less than a couple hours.

Thanks, the truck is going in on Tuesday.the fob needs to be constantly in the slot or the truck doesn’t recognize the fobs. The keyless entry only works on the passenger side of the truck. We shall see what the dealer says on Tuesday. I hope this truck isn’t a nightmare like my 14 was.

Did you ever get this resolved? If so, what was the issue? My truck does not detect my fob but all other functions on the fob work correctly such as lock/unlock, remote start, & tailgate release. Nothing is making sense.

Cooter Brown,

Did you ever get this issue resolved, 2021 Sierra AT4 is doing the same thing. Key fob will work all functions remotely but truck will not detect fob for push button entry or start. My service department is currently unable to get it working.

Hi There im having the same issues here, 23,000 miles on my 2020 Trail boss Silverado and im not sure if I accidentally pressed some buttons in my remote that messed up something. but.  when I try to start it says that there's no detection of remote and then tells me to put fob in slot but I have to hold start button and press brake for a while to start.  haven't had any issues until now.  and  Tire pressure monitor system stop working and light came on in the dash.  Don't know if this is related.    Got home and pulled out my xtra FOB control and also did not work.  Remote start will not work, can't even get door locks to work with the remote.   Does any one know what's going on.  Would hate to take it to dealer and spend who knows how many days waiting for them to fix it.   Im going to check for fuses and try to find a way to maybe figure it out.

There are two different antennas that work with the keyfob. One for the distance functions (remote start, unlock, lock, panic, tailgate release) and another for proximity functions (door unlock/lock buttons). The antenna for the proximity functions is located in the center console/jump seat.

 

If you've recently done a center console/jumpseat swap, it's likely that you either didn't plug the harness back in properly or that the antenna in the new jumpseat/center console is missing/damaged.

 

If you've made no recent modifications, there has been a few instances where there were issues with the keyfobs and how they were programmed. Your dealer should be able to reprogram them to fix it.

Not center console or other, found active water leaking in channel in back window (had taken it in last winter because inside windows would actually ice up in winter and they couldnt find leak) and I started having some electrical issues then and told them.

 

There are 2 SB's that cover my issues EXACTLY: 

 

1) 18-NA-383 August 2020

     Water Leak at Rear Sliding.  Window

     (IT SAYS FOR 2019'S BUT A BUNCH OF 2020S HAVING SAME EXACT SAME PROBLEM)

 

2) 16-NA-061 December 2017

     Service Tire Monitor System/Tire Pressure Display Dashes/RKE Short Range/No Fob Detected Message

     (IT SAYS.ONLY GMC YUKON 2015-2018 MODELS AFFECTED)

 

I had to look online and find these SB's myself. Of course, when I took it in to dealer last winter (and it was still under the Bumper to Bumper warranty) they couldn't find anything.

 

Taking it in tomorrow with both service bulletins in hand, but they have already said I have to pay for it myself and try to deal with GM after the fact. Will post update

I have a 2020 GMC Sierra 1500 AT4 Duramax, my issue is the dash will not light up when entering the truck, or it will say "Remote Learn Pending", either one will not allow me to start the truck. The dealer said it was the Fobs and at my expense replaced both of them which I questioned. Problem is still happening. 

 

I can however unlock/lock the doors, remote start from 200' but cannot release the controls once inside to be able to operate the truck. 

 

any ideas or other peeps having same or similar issues?

Driver door window master switch.  We had a truck do this.  There is a PI on it to test the window switch, door harness and the door latch.  We put a latch and harness in this truck, but the window switch is what fixed it.  

 

Dealer can pull it up, PIT5860.

I have a 2019 Sierra 1500.  Very intermittent issue with the push button start not working. All functions on the key fob will work, however the push button start will not work. OnStar says this is an on going issue with GM.  This happens to both keys.

Is it possible that this is part of the Chevy PIT5860 SB?

 

This is very frustrating.  Thanks for your help!

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
