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.
