I have a friend that has an 03 completely stock truck, today he locked his truck went in a store when he got to his truck driver door wasn't locked cause he left keys in it. so he opened door alarm went off, he took keys out of switch and turned alarm off. He put keys in truck started it and alarm went off again, once again he took keys out turned alarm off. he put keys back in and started it up drove about half of a mile it shut down and will not start now. they have unhooked batteries and still wont start any help!!!!?
