the only time they should auto lock is if you unlock with the remote and dont open a door in 45 seconds or so. also, if you unlock with the remote and only open the hatch, they will relock. other than that, they shouldnt auto lock.
edit: oh, you have scion security. they should auto lock also when you start your car with the doors closed.
