“It (the key fob) does send a signal continuously, so it drains the battery in the key fob and its causing an excessive drainage on the battery of the automobile,” noted Freeman. “A computer is identifying that signal saying I’m ready to start.”

According to Freeman, if the key fob malfunctions, the automobile frequently won’t start because the computer system won’t acknowledge that the key fob is present in the vehicle.

“In most situations, the owners’ manual will clear that up for you, or practically any auto repair facility can replace that battery,” Freeman continued.
