Do you install the key's battery with the correct polarity ? (+ - correctly ?).
Recheck the + - in the battery before go further !!! Good luck !

fob hell

Its not the batteries the car is not responding I used a camera to see if the fob was sending out the signal it is if its the right signal don't know. How do you get the car and fob talking to each other again. So if you have any idea or trick would love to hear it please
