There are so many good reasons to carry keys. Why carry a yubikey, or a license for that matter? Because good security is about what you have, not just what you know. It's about authentication.
In the spirit of the present article, mechanical locks (especially for anything car related) are better. You can't hack into them. If you force or break them, you are forced to leave physical evidence behind that you did so. Not so for a Bluetooth or WiFi hack. This is why I will not enable my smart garage door opener. I don't even have pay by phone, because they offer an attack vector via NFC directly to my bank account. I carry credit cards instead.
Sure, carrying all those pieces of metal is annoying. I got a KeySmart to help mitigate this. I carry my car key in my wallet with my cards. It's worth it, and there are ways around the costs.
