3. Car keys
If you’ve bought a newish car in recent years, you may never have touched it with a key. Modern cars come with key fobs and mini-remotes that can lock and unlock the car with the push of a button.
Some don’t even require that: When I get close enough to my car, it senses that I’m carrying the key fob and remote, and it unlocks the door once I encircle the handle with my hand. I can start the car from inside my home so it warms up while I finish getting ready. And I never have to put a key in the ignition like the old days — the car has a start button instead.
