Great lock with lots of features and excellent app
This lock is great. It has lots of features and everything works well.Installation was simple. A template for hole is provided for hole cutouts if you are installing it on a new door.I bought it for my bedroom door, and the main requirement was that it have a good fingerprint reader, so that I could get in quickly without needing a key or to punch in a code. The reader works very well and very fast, I’d say less than half a second to open. One thing I love about it is that the reader is angled at roughly a 45 degree angle, which makes putting a finger on it (I typically use my thumb) more comfortable than most fingerprint locks, which have vertical fingerprint readers. That may seem like a little thing, but it just feels like a more natural and ergonomic position.You can set up numerical codes (I think between 4 and 10 digits), and they can be permanent, one time use, or time-based. So, for example, you can set up a code that works from 4pm on Friday until noon on Sunday, so it’s perfect for an AirBnB, houseguest, maid, etc. The code entry also worked flawlessly.Three keycards are included. You just put the keycard up against the keypad and the lock opens instantly. Honestly, I don’t really foresee using them – as great as they work, I’ll just use the fingerprint reader and avoid having to take anything out of my pocket.The backup keys provided in case of power failure (i.e., dead batteries) work fine. One minor nitpick is that the keyhole is hidden behind the face of the front handle, accessed by pushing on one end of the handle. It works fine, but my question is, will I remember 5 years from now (or whenever) how to access the keyhole?The TTLock app is really good too. That was a bit surprising to me, since a lot of apps for these kinds of things seem like afterthoughts. This one is intuitive and easy to use.If you have the gateway for the lock (purchased separately), it connects to the internet though your WiFi, and then you can even open the lock remotely. That’s a feature I’m not planning to purchase, but I can see how it could come in handy for some people.There are a couple of features that I had not read about that I like. One is that the time that the door stays unlocked after being opened is very customizable (default is 5 seconds) through the app. Another is that you can set a daily period of time during which the door will stay unlocked, and then lock automatically. So, for example, you could leave it unlocked at night so that if the kids get scared, they can come in without them having to knock and you having to go open the door.The 4 AA batteries are easily installed. You need to remove one screw to access the batteries.A couple of minor niggles: I got the lock in aged bronze, which looks great, but the latch bolt and strike plate are both silver – would be nice if they were also aged bronze to match. Also, one thing I could do without is the voice saying “unlocked” when the door is unlocked and “locked” when it automatically locks again. You can control the volume of the voice by a setting in the app, but can’t turn it off entirely. I think it’s unnecessary, as there is a light that briefly turns green when the lock unlocks, and you can hear the it unlock and lock, so to me the voice confirmation isn’t needed.But overall, this is as perfect an electronic lock as I’ve found. I can’t vouch for its durability, since I’ve only recently installed it, but I’m very happy with this purchase, and I’m thinking about buying one for my garage.

Absolutely Love This Smart Lock!
The Harfo Smart Door Lock has exceeded every expectation. Installation was straightforward, the build quality feels solid and premium, and the fingerprint recognition is impressively fast and accurate. I love having multiple ways to unlock fingerprint, code, key, and app so it fits every situation. The app notifications and access logs give me real peace of mind, especially when I’m away from home.What really stands out is how seamlessly it blends convenience with security. No more fumbling for keys, no more worrying about whether I locked the door, and guests or family can be given temporary codes in seconds. It’s stylish, reliable, and has made my daily routine so much easier.If you’re considering upgrading your home security, this lock is absolutely worth it. Highly recommend!
