09 Tacoma key fobs quit working... but not bad fobs!

Ok, key fob has a new battery, and it sends a signal.

Bought new FOBS just in case... and can't get them linked to the truck...

I checked FUSE number 6 under the dash, and it is good.

I am ASSUMING that the "door receiver control module" is bad???

But that is very pricey if I am wrong!!!!

Any suggestions on how to fix or know for sure???

Please and Thank You.

Keys work in door and the interior electric locks work fine!

 

Does it fail to lock or unlock?

If it only happens when trying to lock the doors.
It could be a bad door (open) switch.

You can’t lock the doors with a door open, or the keys in the ignition.
