you can take a metal coat hanger and bent it into a long metal rod and a screwdriver and a cloth and take the cloth and screwdriver and pry the top of the driver door only a inch enough to insert the metal rod, on most cars its pretty flexible, tried it on a honda civic reborn and just push the unlock switch on the drivers panel or if you have a different car try to pull the door lack handle or tab or whatever you can reach, only takes 5 min works every time.
used this method to get inside a pajero mini with locked key as well as a civic.
