True, the wireless unlocking functionality is very convenient, but that's only when it works. As many users here have commented, the reliability of these types of locks isn't consistently high. Maybe for you it is, which is great.
Adding NFC powered and Touch-ID authenticated unlocking functionality to locks like this could be a compelling feature (assuming Apple allowed it). Fingerprint authentication adds a layer of security that is not present with wireless locks. Correct me if I'm wrong, but locks like the Schlage simply unlock when you walk within range? This means if someone gets a hold of your phone, they automatically gain access to your home. This may be unlikely and I assume this feature can be disabled in such a scenario, but is that a risk people are willing to take with their families/homes? For me, it's not.
I contend that pulling out an iPhone would be much more convenient than pulling out a key, in the same way that I find Apple Pay to be much more convenient than pulling out a credit card. Using a mechanical key requires pulling out your keychain, selecting the right key, precisely aligning it with the lock, and inserting/rotating it. An Apple Pay style lock would only require pulling out your phone with your thumb on the fingerprint sensor and holding it up to the lock. That's four steps cut down to two. Additionally this could be done in the dark, as little precision is required, unlike mechanical keys. Personally, I would find this highly convenient.
Of course the convenience factor would go up with an Apple Watch - nothing needs to be pulled out of your pocket, the device is authenticated to you, and I imagine it would be more reliable/robust than bluetooth/wifi locks. In my mind that is the most optimum user experience, all things considered. Just my humble opinion 🙂
While some locks do unlock just by being in the vicinity or by simply touching the lock, the Schlage does neither. With the Schlage Sense, you can open the app on the iPhone and click the screen, use siri to request a lock/unlock, using the name of the lock that you have assigned, or directly enter a code using the touch screen on the lock.
I do like the idea of NFC and Touch-ID, but I have no idea if Apple would allow this for an entity outside the phone other than Apple Pay.
And yes, pulling out the iPhone would be a bit easier than pulling out the key.
What I like about the Schlage is the ability to use Siri. I can request of Siri, using my apple watch or iPhone to unlock the door as I arrive home. The problem is the remote activation with Siri via the AppleTV 4 (I think home kit is also supposed to work with atv3, but I'm not sure) has not been very reliable. You can't use the iPhone Schlage app remotely, only within direct Bluetooth range. Which means you can't assign codes to people remotely.
But at least if the remote home kit was reliable, via Apple TV, it would be OK. And the other day, all communication with the lock failed, even inside my home.
I must admit, Schlage customer support is very good. They replaced the first lock. So far, the communication seems to be better, but I'll have to wait for more remote testing to determine if there really is an improvement.
There is also the Schlage Connect locks. Very similar in appearance to the Schlage Sense, the Connect uses open source z wave to communicate with a hub that you would purchase separately that then connects directly to the Internet. This is apparently very reliable. But you give up voice commands as you have with Siri and the Sense lock.
I just think that the remote home kit bluetooth combination isn't yet ready for prime time. Just too unreliable for now and it depends upon the Apple iCloud functioning perfectly. And that may not be realistic yet.
