Correct. The key is displayed in front of the currently selected car ... which should also be the one displayed on the Home page. Go to the garage, view a car, even if you don't click on SELECT (with the key ... hint!) bottom-right of the screen, when you exit your garage that car will be the selected car displayed on the Home screen.
