The keyless entry is controlled by the RF module. It is what senses the keys and what allows the vehicle to start when a correct key is detected. I know there are some issues with this module. But what you can try first, which I have seen work in the past, is to disconnect the battery cables. Then touch the two cables together to drop any remaining voltage. Then reconnect them and see if the car will start. If not then you will have to bring the car to the dealer to have them communicate with the rf module.
