A slim jim is a thin strip of metal roughly 60cm long and about 2-4 cm wide Slim Jims are used to unlock automobile doors without use of a key or lock pick. It acts directly on the levers and interconnecting rods that operate the door, completely avoiding the complexity of dealing with the lock mechanism itself. The hooked end of the tool is slipped between a car's window and the rubber seal, catching the rods that connect to the lock mechanism.
