Vaxhaull astra central locking?

hi
i would like to amend my central locking system for vaxhaull astra Estate 2008. i want a system that will be all controlled by the driver. so driver can lock all the doors even if one is left wide open at that time. so as soon as you shut the door it goes to lock.
if driver open the driver door from inside it only open driver's door.
passengers will be unable to open the doors from inside if driver lock them.
