No Key Detected

[MachMan2004]

Good Afternoon All,
Well here we go, less that 400 miles and a error message. I have a "No Key Detected" error popping up and my unlock with the inner door handle no longer works, I tried with both key fobs and I am getting the same result. Has anyone seen this and/or found a solution?

Has the truck been sitting for a while? 1) Drive it for a bit and retry. 2) Could be weak/dead key fob batteries. Change and re-attack. 3) Disconnect the truck battery to reset things and re-attack.

I’m certain there’s a thread here covering this…try the search engine. GL

Sounds like a dead FOB battery.

Maybe a module issue or antenna(s) issue, if you put the key inside the cup holder backup slot area will it start?

If I put my fob in my pocket with my phone...this happens. I replaced both batteries it still happened. Did some research...common problem...phone interference. Not saying it is your issue...but think it was mine.

Thanks going out to everyone who posted. The issue is resolved.

I disconnected the negative and positive terminals and let it sit for about 15 minutes. Hooked the terminals back up at tested the truck. The inner door handle unlocks the truck and the error message is gone. Happy Days.

Anyone else having this issue. Just happened tonight to me. I have already
-replaced key fob battery
-disconnected truck battery for 15 minutes
-fob will auto start the truck but still can't be detected once inside the truck.
-did the cup holder thing, still no joy

Does anyone think the Ford app update has anything to do with this?

This is a strange one.

I think there's a bulletin out on it, and an OTA update fix. Not sure which module it was for but didn't sound very serious.

Found the TSB:

Thanks so much. Hopefully an easy fix, but curious how I get the truck to the dealer now it won't move because of the FOB issue.
