The keyless power system also has one or more alternate power sources configured to provide electrical power to the one or more electrical components. The keyless power system also has a controller configured to determine a power-level requirement of the one or more electrical components and activate at least one of the one or more alternate power sources to at least partially satisfy the power-level requirement based on whether the ignition switch is in the 'OFF' position.
