Try this: from inside manual lock all the doors except the drivers, with key in hand exit the vehicle and manually lock the drivers door with the key, watch the dome light and when it goes out wait at least one minute then using the key unlock the drivers door and see if it will start, if not then a trip to the dealer is going to be necessary, they will have to go in and reprogram the security system, if you have more than one key make sure you have it with you so they can make sure that the system responds to both chips.
