An illuminated key blank is provided with a blade and a head integral with the blade as a single piece. A cutout is preferably formed in the key blank head so that the head is substantially U-shaped, and a battery is disposed in the cutout between the arms of the U. A light source, preferably a light-emitting diode (LED), is selectively electrically connected to the battery. A casing is sealed around the head of the key and the battery, and the casing retains the light source in place so that the light source shines light substantially in the direction of the blade. The light source shines light which is preferably the same or a contrasting color as the color of the casing so that the key may be identified in the dark.
