Using the pump air wedge, lock picking car locks is not easier. The pump wedge acts as a wedge: by placing it between the windshield and the body of the door and pumping it up, a space is created between these two elements of the door. This makes it easier to use lock picking tools in order to be able to open the car door without damaging it. The U-shape of this KLOM air wedge ensures that you have more space than with the previous air wedges.
