I frequently forget to unlock my door on the way out to walk the dog in the morning, and have to ring the doorbell, possibly waking people up, just to get back in. I wish the door would just know it’s me and open.
Modern car keys enable the opening of doors just by their presence. While that’s a pretty cool piece of tech, it makes me wonder why we don’t use it elsewhere. Why doesn’t Toyota, or one of the other manufacturers, offer to sell locks for your house that open at the touch of a person holding the car key?
