Abstract
A device for assisting the crippled hand to turn a key in an automobile starter switch lock has an elongated member that firmly grips opposite faces of the key head and has longitudinal portions which rigidly extend the moment arm for application of turning force. In one form the device has recesses to receive the tabs of a steering column mounted starter switch. In another form, the device has a protuberance to project the key into the recess of a recessed switch on a dashboard. A preferred embodiment has hinged rigid panels with hollowed internal surfaces that mount keys for slidable and pivotal movement along tracked guideways. The internal surfaces have raised marginal edges interrupted by a slot through which the shank of a key may be passed.
