HELP! No Key Detected

[levileb91]

I am experiencing similar issues in my 2017 year. I have replaced the battery on my fob and the truck battery. I can use all the functions on the Fob but the intelligent access does not work to unlock/lock. When I try to push to start the truck I get a “no key detected” error.

I can put all three of my fobs ( I bought a third and programmed it with Forscan) in the cup holder slot and can start and drive the truck. Putting the key in the backseat does not work.

I’ve replace the IA antenna in the tailgate handle. Put new batteries in every fob. Replaced the trucks battery. Did a BMS reset. Used forscan to check for DTCs that may show and get nothing. Did module resets on BCM, RTM, and pretty much every module in hopes to reset the issue.

This all started after going through the car wash. Any help/input is greatly appreciated.

I am having the same issue. What ended up fixing it? Replaced FOB battery, disconnected truck battery. FOB will lock/unlock and autostart truck, just wont be detected.

Post #10 was my solution. Very strange circumstance but maybe that antenna is your issue.

Thanks a bunch...this forum is too cool. I think its the antenna too, or an update that did not go through. Ford was not much help on the phone. At least the warranty will cover the tow truck that I'll need to get it to the dealer. Just a pain the ass though...

Turns out my issue was a severely corroded BCM. Needs to be replaced...hopefully that fixes it.

um.....??? you driving in the ocean above the door line?

is your carpet wet there by chance? the only way i can see corrosion on the bcm is if the moonroof drain tube clogged and water ran over the top of the bcm as it traveled downward.

Sorry for the late reply...no sunroof on this Raptor. Maybe the AC? Part came in yesterday so should have it fixed by cob Monday and should know more. I love this truck but it is down way to much so will be getting rid of it .
