Many vehicles utilize keyless entry devices. Presently, the industry standard for powering most keyless entry devices, such as a key fob, is to use a small battery cell, such as a lithium ion cell that is intended to sustain devices having a low electric current requirement (e.g., 10 mA). However, in some instances, the small battery cell cannot provide enough electric current for keyless entry devices that have higher electric current requirements (e.g., 80 mA), such as keyless entry devices that send high powered wireless long range transmissions.
