My problem is my doors won't lock/unlock with my key FOB. My trunk releases with the FOB just not the doors. Battery was just replaced i just replaced it. I'm trying to find if anyone knows how to reset the transmiter to the car? It may not be the key FOB, but it sounds like a good place to start to find my problem. Any info would help

 

ive gone through 3 key FOBs they just stop working i think its something in the buttons not the battery

 

They are like remotes ,If you get anything in them the little contact pads will not.
You can try taking it apart and cleaning the pads off and the spots where they make contact with rubbing alcohol and give it another try.
