This system integrates with the keyless entry, utilizing the lock button for control, and incorporates GSM cell connectivity to operate with the Lexus RES+ mobile app. Offers additional features such as vehicle status and location.

To remote start with the Lexus RES+ app, press the "START" menu and then the "ENGINE START" button. Enter PIN code when prompted.
Note that once any door is opened, the engine shuts off as a safety measure.
