Abstract
Battery fretting or corrosion in a key fob is reduced or even eliminated by firmly holding the fob's battery against electrical contacts and holding the battery away from key fob components that are subject to deformation or deflection. Reduced battery movement relative to electrical contacts thus reduces or eliminates abrasion of the battery's electrically conductive surfaces.
