Hey everyone. I have a 2006 Mazda 3 GT. When I press the lock button on the key fob, the horn doesn't honk nor do the lights flash at me. When I hit the un-lock button the lights do not flash either. When I first got the vehicle, the problem did not exist. Since then, I have taken it into Mazda and they found nothing wrong. I tried to re-program it to see if that would help anything... it didn't. Any Suggestions?????
