A keyhole sighting device for mounting on a key receiving member at a kehole therein. A shell projects forward from the key receiving member and has a funnel-like interior cavity converging toward and terminating in a key receiving opening for mechanically guiding a key to a keyhole within said key receiving opening. The shell is of elastomeric, light emitting material and is fixed to the key receiving member as by a rearwardly extending elastomeric skirt or rearward facing adhesive layer. A modification employs a light reflecting (e.g. white or light colored) material surface rather than a light emitting material to enhance visibility in the dark.
