The whole door lock/keyless start system needs some real work. There are times when the doors won't open even though I have the key in my pocket and grab the door the same way I do every time. Other times, I try to start the car, with my foot on the brake and the car in park, and nothing happens (especially true if you step outside of the car with the key while its still running and then come back and turn it off). . It's as if the car is dead. I have to get out of the car, close and lock the door and then come back in and try again.
