• receiving a command to modify a configuration of an electronic switch from a first configuration to a second configuration, the electronic switch positioned within the vehicle in a conducting path between a starter motor of the vehicle and a battery of the vehicle, wherein the command is received from a remote computing device that is separate from the vehicle;
• and
• in response to receiving the command, transmitting a signal to the electronic switch via a two-way communication channel connecting the network gateway device to the electronic switch, the signal causing the electronic switch to modify the configuration of the electronic switch from the first configuration to the second configuration, wherein the first configuration of the electronic switch is a closed configuration creating an uninterrupted conducting path, and the second configuration of the electronic switch is an open configuration creating an interrupted conducting path.
