TRY this jam open the inner and outer door handles.. tightly rolled up newspaper/ cardboard squashed in behind the handles and get into the rear seat boot firmly against the door panel as near as possible to the opening edge of the door push firmly and then a sharp kick .. and remember slippers, bare foot, trainers, NO.. boot yes
