<human>:  How does a remote car starter work?
<bot>: A remote car starter is a device that allows a user to start a car from a remote location. Generally, the starter is activated by a remote control, sending an electronic signal to the car’s ignition system, allowing it to start without the need for a key. Some starter systems also allow owners to start their car remotely via a smartphone app. Remote starters can also offer convenience features like unlocking the doors and rollingdown the windows.
