Almost certainly not. For one, this hack only unlocks the car, it doesn't start it or allow it to actually drive. The reason they're stolen frequently is the same reason the Camry and Accord used to be the top stolen vehicles ~20 years ago: they're best-selling vehicles and thus the parts from them are relatively valuable and have a worldwide market.
