The device is activated by pushing the key into the slot in the plug or cigarette lighter and engaging the contacts by pushing the plug inward.

Abstract: A key bow cover which is adapted to be placed around the bow of a key and is composed of a pair of plates which are hingedly connected together by a rivet or other similar fastening means at the top end of the cover. The bow of the key is adapted to totally fit within one of the plates with there still being sufficient excess space to insert a money coin, such as a dime in United States currency. There is sufficient space in the other of the plates to also insert a similar coin. When the plates are located together to completely enclose the internal chambers, there is a fastening means provided to secure together the plates. Whenever it is desired, the cover can be opened and the dimes removed and used for whatever purpose deemed necessary, such as a telephone call. An insert is to be normally used within the cover to matingly cooperate within the opening provided by the joined pair of plates. A second opening is provided within the insert to matingly fit with the particular shape of key bow.

Abstract: A key retainer having a structure such as to substantially reduce the risk of loss by bouncing out of a pocket. A block of compressible foam such as polyurethane foam has a key chain attached. By compressing the block of foam with the hand and inserting it into the pocket, the foam resiliently expands, substantially filling the pocket or otherwise exerting pressure against the material of the pocket. These forces as well as the accompanying friction forces hold the key retainer securely and safely in the pocket, even in the presence of bouncing or inverting the pocket.

Abstract: Two elements are hinged together by one end thereof and are detachably locked by the other ends to form the key holder.
