My home is now renovating, and I am looking for a smart lock.
After few weeks for reading. I end up decide go back to the fingerprint lock. There are few reasons.
1) I've been using the fingerprint lock for many years already. Never have any serious issue. The only minor issue is that when my hand is dirty, the fingerprint lock may not able to recognize on the 1st try.
2) There are many generations of the fingerprint lock already, almost all problem is fixed. The new fingerprint lock even has a backup port to access the 9V battery from the outside, never need to worry about battery issue). On the other hand, the smartlock at this moment is still the 1st gen product, relatively more issue. However, for a lock, I really need >99% reliability.
3) Only few smart lock can lock / unlock the door without pull out the phone. If I don't mind to pull out something, sure the key is quicker. And using the key is easier than open the apps etc.
4) For those smart lock which don't need to pull out the phone (e.g. Kevo), seems not reliable enough. Only around 60% accuracy (they are secure, won't open for anyone don't have the e-key. However, may need try more than once to lock / unlock the door, which may be a problem when I want to get in / leave my place in rush).
5) Yes, metal key is the backup, however, one of the big reason that I want a smart lock is because I don't want to bring my key. That's why I need the lock has >99% reliability. I won't take my key.
6) Current generation fingerprint lock operation is quick, very quick (if compare to those smart lock which use e-key, but not open by apps. Again, I don't want to pull out my phone for unlocking the door).
I really want a smart lock badly. However, just no smart lock that fulfill my personal requirement at this moment. If there is a lock that is "fingerprint lock + smart lock". So that I can use fingerprint to operate my door, but can still unlock the door remotely via the internet, and check the lock status / operation record on my phone (e.g. Apple make a smart lock that use the touch ID), that may be a perfect solution for me.
