ABSTRACT:
A car door opening tool for opening a car door of the type having a locking bar located within that functions to open the car door in response to the application of an unlatching force thereto. A shaft of sufficient length to access the locking bar through the car door's window slot from a position outside of the car door is provided with coupling device at its gripping end for both engaging the locking bar and for gripping it in response to a force-couple applied to the handle end of the shaft. By inserting the gripping end of the shaft through the window slot to engage the locking bar and then applying a force-couple to the handle end while simultaneously impressing the unlatching force to the shaft, the car door is caused to open.
