Hi I have a issue with my Mazda 6. My keyfob is not working. I have to open the door manually. Car is
not starting. I thought at first it was battery then I have changed the battery and it doesn’t work. Start button never shows any green light. I tried to start it by pushing the back side of the key it still doesn’t work. It is like every time if I have to start the car I have to jump start the battery first. What might be the problem? Need suggestions

 

Having the same issue. My wife jumped started the car in reverse lol I get codes for smart city braking and the other functions. Foot on brake and push button does not light up. Try to start and nothing. New battery.
