I know many curse the horns honking when the Lightning detects a truck running without a key present. Fortunately FMC allows us to disable it. But, I for one, like it but recently mine quit working. I have disabled it and turned it back on and it does nothing. I have PAAK enable but it doesn't matter whether I have my phone with me or not, I get no horn honks. Before I request a service call, anyone else seen this issue?

Mine only beeps if I lock the truck first before closing the door. If I use the keypad it doesn't and just locks.

Do you have a fob hidden in the truck? I had one in a faraday bag and it suddenly started getting detected. Had to double-bag it.

Mine use to honk at me but doesn't any longer. No clue what's up. I do not have PAAK as an option.

So, I am not alone. sounds like a recent update changed something. I'll be setting up a service call this week. will post here what I find out.

truck running without a key present.
I misread earlier, mine has never beeped when running with no key unless I try to lock the key in it. My walkaway lockimg is disabled.

Mine only honks if I exit and I close the door while truck is on, reminding me that the truck is still on.

My 2023 Pro "chimes" once if I lock it while it is running.
I used FORscan to enable 'silent mode' - before that it used to honk which I found to be too loud.

My related issue is that once in awhile the truck will chime continuously when I shut it off and open the door with no indication of what’s wrong. Cycling power seems to clear the issue.

update: it's working again. not sure why. Troubleshooting I disconnected my phone from PAAK. Key Detect still not working. turned KD off and back on. Still not working. Turned it off again and drove the truck for perhaps a week. Turned KD back on. now it works! ?????? What happened after that was very interesting as I was able to drive the car without PAAK or a keyfob!!!!! But I will start a new thread as this was puzzling. look for "driving without a fob or PAAK"

update . it's not working again. Key Detection that is. suspect that it is related to PAAK but will dig deeper to document before taking in for service.

Have you replaced your 12v battery yet? I noticed you have a 2023 and it seems 3 years is where lots of people start having anomalous issues that eventually get resolved with a new battery.
