I tried all both methods of reprogramming and the key still doesnt work... it wont even lock the door or unlock the door.. you think it needs to be recharged maybe... can i just leave it in the ignition and turn it to position 2... or 3... I drove the x to the store earlier today with the key that isnt working now.. and i almost got stuck at kaiser when the key didnt turn the car over.. but finally it started right up... so it sometimes works and sometimes it dont... but the other key works flawlesly... I think i use the other key more often than the one that dont work now...
