It has to be done with a computer or a specific app. Both require a physical connection to the car. Easiest is Carly (iTunes store/google play) and their OBD Bluetooth connector. You will need to also know some battery information (take a picture of the top of the battery label) when you go to register it. Carly has a free version, but you won't be able to register without buying the pro version along with the battery registration module.
