## Title
Illuminating key fob

## Abstract

An illuminating key fob including a key fob body having a base and a cap secured together. Various compartments, disposed on the base within the internal chamber, store batteries providing a power source to a light emitting diode light source adjacent the key blank disposed within the internal chamber at a front side of the key fob body. The light source is provided to illuminate a key hole opening for insertion of a key produced from a key blank. The batteries are in selective operational communication with the light source to operate the light source upon the alternate activation and deactivation of an on-off button switch on the cap. A loop-receiver opening in the rear side is sized to receive a key ring therethrough. A notch in the cap along the rear side assists in grasping the rear side for insertion of the key ring through the loop-receiver opening.

## Background
BACKGROUND OF THE INVENTION
Various types of key fobs incorporating light sources are known in the prior art. However, what is needed is an illuminating key fob including a plurality of batteries providing power to a light emitting diode power source disposed adjacent a key blank in a key fob body.
FIELD OF THE INVENTION
The present invention relates to illuminating key fobs, and more particularly, to an illuminating key fob which includes a plurality of batteries to provide a power source to a light emitting diode light source disposed adjacent a key blank attached to a key fob body.
SUMMARY OF THE INVENTION
The general purpose of the present illuminating key fob, described subsequently in greater detail, is to provide an illuminating key fob which has many novel features that result in an illuminating key fob which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
To accomplish this, the present illuminating key fob includes a key fob body having base and a cap securingly engageable to each other, each of the base and cap having a front side, a rear side, a top side, a bottom side, an outer perimeter, and an internal chamber continuously disposed between the base and the cap. A key blank is disposed within the internal chamber at a front side of the key fob body. Various compartments, which are disposed on the base within the internal chamber, store batteries to provide a power source to a light emitting diode light source, located adjacent the key blank, is provided to illuminate a key hole opening into which a key made from the key blank is insertable. Each of the batteries is in selective operational communication with the light emitting diode light source to alternately activate and deactivate the light emitting diode light source upon the activation and deactivation, respectively, of an on-off button switch disposed on the cap. A loop-receiver opening, disposed in the rear side of each of the base and the cap, is sized and configured to receive a key ring therethrough. A notch is disposed in the cap along the rear side from the top side to the bottom side. The notch assists in grasping the rear side and in inserting the key ring through the loop-receiver opening by providing a narrower portion through the key fob body than would be provided otherwise.
Thus has been broadly outlined the more important features of the present illuminating key fob so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
