My one remote doesn't seem to be working anymore, when i push the unlock button it won't unlock the car, but the small red lights on the headlight switch inside the car will illuminate as well as the emergency flasher button light on the inside of the car, then they will extinguish after about a minute. Lock and trunk button don't work either. I switched out the battery, but still the same thing. My other remote does work. So anyone know what's wrong with this one remote then? Thanks.
