Afternoon All. New to the forum but not new to my H3, purchased new back in 08. I've been neglecting the door lock issue for a couple years now...no better time than now. Battery in the FOB is good and is the stock FOB, also used the other stock FOB to eliminate it being a FOB issue. I am assuming there is some kind of receiver/antenna/module that has gone bad and is not reading the signal? Thoughts? Appreciate the help and assist. Electronic gremlins like this are always my weak spot, hence the procrastination

Schwarttzy does a great video of how he repaired his.

Pulled out the BCM tonight, everything looks clean, no corrosion or anything visually of concern. Antenna connection is clean and snug. Threw a new battery in both fobs just to confirm. No resolution. Assuming at this point it is a BCM problem and needs to be replaced
