I feel dumb asking this but here goes. My fob won't unlock my doors but
will unlock my trunk, anyone know why?
Inside the fob, above the battery is printed: "Press Lock + Unlock 7 sec to reset", is that supposed to be done at battery replacement each time? Since I've already been using fob since replacement a year ago have I messed up my chances of doing that now or should I put in new battery & start over?
