For a little over a year now, my key fobs have been malfunctioning. I've changed batteries, rotated fobs, but still have the issue of my lock and unlock buttons not working. My alarm and trunk work just fine. My auto start button works, but you have to lock the doors, then press that button, so the function is useless at the moment. What am I doing wrong? Do I need a new fob? Does it need to be reprogrammed? I just got a new car battery this week, and thought that might help, but still same results :/
