Remote Start Lexus Engine via Smartphone
Newer Lexus vehicles can be started via a smartphone. In order to remotely start your Lexus with your phone, you will need Lexus Enform Remote Service subscription, the Enform app for your smartphone (Android or iPhone).
When the vehicle first purchases a new car you will get a free Lexus Enform Remote for one year. After that, you need to buy a subscription.
Lexus Enform's website shows that the Remote subscription can be obtained for $8 per month or $80 annually for many models starting around the model year 2016. Call your local Lexus dealer to check if Enform is available for your model.
