I had the same issue when my only keyfob failed. I tried to use the digital key but it only opens the doors, turns on the air and can monitor your GPS on it if you've loaned your car out. In other words, the digital key does everything but the most important function, move the car. Only way to get the alarm to quit when you've used this key or the baby mechanical key in the fob is to rub the bottom of the fob on the start button. Nothing else works....good luck, second key fob would solve both our problems.
