The Hanger and Ruler Trick
Use a hanger and straighten its knob to make it absolutely straight. Then carefully push it through the rubber casing between the window and the door above the lock system. The next part will require that you fumble a little till you are reach the knob and are able to push it through to the end. If you have a steel ruler, this will become a little easier for you to take care of. When you push against the door, the lock will open and you can enter the car.
