keyless entry/ starting is a great feature to have. All you have to do is keep the key fob in your pocket, or purse and when you walk up to the car and grab the handle then the door will unlock. You don't even need to pull out the key to start the car, if the car senses that the driver has the key fob in the car, all you have to do is push to power button then the car will start. And to lock the car all you have to do is push the button on the handle to lock the car. If you accidentally leave the key fob and lock it in the car, the doors will unlock and a buzzer is sounded. The only bad side of it is that you need to make sure that your key fob will never run out of batter cause it won't be able to transmit to the car for it to start.
