Abstract

A device is provided for the unlocking of car doors despite the existence of anti-theft devices such as an inner shell. The device is bent in such a way so as to circumvent the inner shell placed in car doors by manufacturers which prevent the use of other door unlocking devices. The device also is bent in such a way so as to unlock a car door despite the existence of anti-theft devices such as plastic coating on the locking bar that prevents other earlier devices from being used. The device is a continuous metallic rod bent at precise angles and at precise lengths so as to take advantage of the spaces in between the window and the outer shell, the hole within the inner shell, and the distance between the hole and the inner shell and the locking device. The device is constructed very efficiently and cheaply.
