“Car is equipped with remote start. On april 20th I parked in the garage, put groceries away including some that went in the fridge in the garage. The Corvette keys were in my pocket. I set a timer for one hour for items I had put in the garage freezer to chill. When I went back at the one hour alarm, the vehicle was running in the closed garage. To use remote start the vehicle has to be locked first and I never lock the vehicle in a closed garage. Chance motion of those keys in my pocket had locked the vehicle and initiated remote engine start. …”
