hi mate what you will have to do is remove all the screws to the inner door card that you can access then remove rear seat base and grab the bottom of the door panel and pull this will break the fixings underneath but the panel will go back ok sometimes you can get a thin nose pliers in there and unscrew the screws once the panel is off dont think that its the latch at first but check the wiring that goes from the body to the door. if the wiring is ok the only way to open the deadlocked latch is to smash it to bits ( just make sure the window is up though ) have fun.....
