I need help
last month my car stopped acting to the key fob buttons (open and lock doors). I have tried the re-syincing all goes well right up to the point of pressing the buttons on the key, nothing happens, it's like the car is not receiving a signal, the battery in the key has been replaced, and lights up when the key is pressed, even taken the key to be re coded, which works for 10 mins max then problem continues. What part of the car is responsible for the signal, does it need replacing any help is appreciated. I'm outta ideas
