New 'round these parts but really like what I see so far. Got an '04 FX 35 AWD with 162k miles on the ODO. Just recently the horn stop beeping and the lights stop flashing when I press the lock button on the remote. I checked the option set-up and it is set for those things to happen. The locks do engage so it is really just "one of those things" but still I can't figure why it just decided to stop. Any ideas?
