My boss just bought an 07 Dbl cab Sport. He recieved a plastic key that if he takes it to the dealership they can cut it to fit the lock on his truck in case of a lock out. It is suppose to not let you start the truck though. They recommend you keep it in your wallet. I have the same truck except an access cab and its an 06 and I never heard about this feature until now. Anyone know if it works on earlier years? Seems like a great idea seeing I have a habit of locking myself out.
