Passive entry /no key fob detected

[Dcornz]

So a few days ago my passive entry quit working /no key fob detected
Figured it was the battery in the fob, same results with new battery

Fob works as it should for unlock lock ect

To start the truck I have to push the button with the fob
Tried unhooking truck battery multiple times

I'm getting a code in alpha I will attach a picture

Does anyone know where antenna #3 is supposed to be?

Posting info about your truck can be helpful (model year, etc). But do you know if you have had or have the rear window leak? The security module is on the back wall and can get damaged if there is a leak.

The window is a little leaky, I had the RF hub out last night with no signs of water intrusion or corrosion, no signs of water in that general area
