So the sensor for my key broke today on my 2008 Mazda 6. I know its not the key, cuz it still lights up, and both my key and the spare key wont work. So where is the sensor on the car for the key located?! and what could it be that I need to fix it? I dont want to take it to the Mazda repair shop cuz i cant lose my car for a number of days, and its not an urgent thing, but i would like to fix it. so please help!
