In some cars, your car key fob can remote start your vehicle during chilly days.
Try pressing your unlock button twice, holding down the second time until all windows are open.
For cars that don’t do this automatically when they lock, try holding the key fob lock button for ten seconds.
now many newer models have key fobs that allow you to open your back hatch with just the click of a button.
Should you choose to go keyless on your next model, your fob can serve as a way.
