“NO KEY DETECTED”
Howdy all!
24 Lariat 7.3, 5,200 miles. Strange issue just started yesterday. Truck knows when I approach, welcome lights come on, but won’t unlock when I touch the handle. Unlocks with fob or keypad. Get in, truck starts with push button, then get chime and message on screen, “no key detected”. Truck drives normal. Get out, can’t lock truck with button on handle, but can with keypad or fob. “Walk away lock” still works, so I know the truck recognizes fob. Anyone wanna guess what’s going on?
TIA

Does it do it with both fobs and both doors (assuming it works on both doors).
In simple terms I would guess that the circuit is similar to a touch lamp to detect the touch and unlock the door. As @99powerstrokedF250 said let the dealer take care of it.

When you touch the door handle it triggers the module to seek out the RFID in the fob, and if it doesn't see it, then it wont unlock or lock.

If it were an older truck I'd agree, but it's a '24 with 5200 miles on it. Unless someone is sitting there pressing buttons on it constantly, I wouldn't think it would be the fob battery. I'd be thinking it's the RFID module, especially if it's both fobs doing it.

Thanks for the responses so far.
No difference with either fob. The truck must be sensing the fob, or the welcome lights wouldn’t come on, or the “walk away lock” wouldn’t be working. Also, I don’t think the truck would start if it didn’t sense the fob, but it starts and then I get the notice.
Yes, I could take it to the dealer, but was hoping someone here might save me a trip.

Thanks for all the replies.
Well, the battery is at 12.54v, I can use either fob to remotely lock, unlock, global open and close the windows, and remote start. I can get in the truck and start it with the push to start button if I have either fob in my pocket. The welcome lights come on when I approach the truck, and the walk away lock works when I move away with either fob.
I guess it’s off to the Ford store
