is the passenger door the same?
i take it the open / lock button on the finger plate does nothing either.
the only thing i can think of at the moment is to take a Stanley knife to the door card and pull the door pin up. this should allow you to open the door and then remove the door card properly and then replace / fix the lock module.
obviously this is quite a drastic solution and will mean you'll have to replace your door card.
unfortunately this is the only way i can see of getting your door open.
