Well i got a Mazda 6 2006 used from a dealership everything works fine there are some things i wonder about but over all its good car but my transmitter to lock the doors and open them and or pop my truck or press the emergency button does not always want to work i have had the car not to long but when i press the buttons on the transmitter the light will show up as if it is in use and or the command was being used but nothing with the car. The transmitter is a switchblade key but if thats not the right term for it im sorry. But anyone know how to help or try to make it work again.

 

Have you tried replacing the remote battery?
