Abstract
Abstract A key attachment for affixing identifying information to a key in which a handle has a recess therein and the head of the key is retained in the recess, with the shank of the key projecting outwardly from the handle. A sheet with the identifying information is disposed on the top of the key in the handle, and a clear cover is disposed on top of the sheet and is locked to the handle. The means for retaining the key head in the handle may be a filler piece in the recess having a cutout conforming to the shape of the head of the key, a post or rivet interconnecting the key and the bottom of the recess, a layer of malleable material in the recess in which the head of the key is embedded, or a layer of material in the recess having a high coefficient of friction against which the head of the key is held under pressure.
