I wouldn't call the concept unnecessary and ridiculous ... just the poor implementations so far (and the high prices).
Keys are pretty old technology and in some ways, I can't believe in 2016 we're still walking around with little pieces of metal on rings, all cut with a bunch of notches, as the way we lock and unlock our doors.
I hate keys because I always wind up with more of them than I want to shove in my pocket at one time. So I remove the ones I don't use often, and then I have no idea which ones are for which locks when I wind up needing one of them again. (Someplace around my house, I've got a ring for the keys I don't carry that includes keys for my parent's front door, back door, side garage door, and a key to get into one of the supply closets at my workplace. I've also got spare keys made for our own house, mixed up with a few keys that I think are left over from the last townhouse we rented and others for locking storage boxes we've owned at one time or another.)
At least I can tell which keys go to our vehicles since they've all gone to those keyfobs with the physical key as part of the fob.

Laziness don't come cheap it seems. Heaven forbid it takes you 2-5 seconds to unlock a lock an actual key. While I love the advancement of technology, some things are unnecessary and ridiculous.
