Toyota is charging drivers for the convenience of using their key fobs to remotely start their cars. According to a report from The Drive, Toyota models 2018 or newer will need a subscription in order for the key fob to support remote start functionality.
As The Drive notes, buyers are given the option to choose from an array of Connected Services when purchasing a new Toyota, and one of those services — called Remote Connect — just so happens to include the ability to remotely start your car with your key fob.
