Thanks for all your answers. I'm still putzing around with this. I appreciate all of your answers as usual just been super busy and haven't been checking all the threads.
Either way, the fob is still not working. Kind of crazy...checked all the contacts and soldering points on the board and they seem fine...nothing looks worn, scratched etc. I figured since praying the key fob shells apart took a bit of force, that the looping contacts that are supposed to make contact with the batteries is at fault but now I don't know.
It says above it's only supposed to touch one battery. Which one is that? The top one? So basically the little "hooks" for lack of better term are supposed to hook on one of the batteries? Maybe mine are too bent?

Any tips are super welcome. And maybe I'm looking in the wrong direction...maybe it is a completely different part of the board that's the culprit. Not sure if anyone here had issues with their fob before and were able to fix the board...what was the culprit?
