2018 TRD Key Fobs Not Working As Well As They Used To

My truck is 7 years old, and I am using both of the OEM key fobs. Recently, they both stopped operating normally. And yes, I have already replaced the batteries twice and even tested the battery's voltage (3.2v).
I used to be able to lock/unlock the truck from inside my house. I used to be able to touch the door handle to unlock with the key in my pocket. Now I'm lucky if I can get the door to unlock when I am holding the fob in my hand and touching the handle.
I think the problem is in the truck. The BCM perhaps.
Any tips will be greatly appreciated!

 

I’ve noticed something similar with mine

 

Gently rub steel wool on the metal contacts where the coin battery sits. A couple of years ago, this helped my Fob to work better when a new battery did not help.

 

My 2020 is doing the same thing

 

I've got a 2021 and the FOB keys aren't performing like they did the first 2-3 years.

The actions explained can sometimes take a second to react on my FOB.

I'll watch it closely.

 

I agree with TA 2016.

The battery contacts may be dirty or have some corrosion on them.

 

I had similar problems with my 2017….changed the batteries with some Amazon generics a couple times, didn’t fix it. Swapped to Duracell and problems have been gone for over a year

 

I'll clean the contacts and hope for the best. But again, this is both fobs acting the same way. I was thinking the BCM. Any BCM theorists out there?

 

The Body ECU has nothing to do with the Smart Key, all Smart Key functions are handled by the Certification ECU, several antenna's, and the Electrical Key/Door Control/TPMS Receiver.
Service info doesn't really specify a minimum range that it should work in.
