Review: 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.
Review: Great device at a great price so far - Install was easy, didn't love that I had to drill through my door, in case the lock doesn't work out but that's my only complaint so far. I placed it out doors under a very small awning where it may experience a small amount of water during a heavy rain. I will update if it doesn't last. I have been buying locks like this for years (they all die after 3-4 years) and I usually pay about 180 for a much more basic push button version....technology has come a long way. The fingerprint scanner is fast and accurate. No need to push anything to wake it. The RFID card does have to make actual contact with the key pad, not just near it. I am aware you can buy boosted signal RFID cards....not sure if they are compatible with this handle. The led on the touch key pad is hard to see during the day and is kind of awkward to wake...you sometimes end up entering a key just trying to wake it or turn on passage mode (doesnt lock automatically) by mistake. BUT i have no use for the key pad anyway so i don't care. I like that the numbers on the pad circle when your fingerprint or RFID are accepted and make and X when its not. Sometimes its the details LOL. The programming was very easy. I just hate that even logged in as an administrator you have to hit the set up key (under the screwed on battery cover) to add a user or adjust settings. Overall great deal though! UPDATE!! After one full winter season outside, still going strong and working great!!

## Questions & Answers

**Q: Is this lock weatherproof as to rain**
A: No it is not , i have this lock and if it gets wet it glitches badly . I have to put a piece of plastic over the lock to keep it from getting wet . Hope that helps you

**Q: So there is no way to lock this from the inside?**
A: I assume you mean from outside entry. If so then yes there are two ways. Normally it will automatically lock after a couple of seconds, unless it is in “passage“ mode. There is a switch on the inside just above the handle for private or general mode. In private mode it will be locked and only an administrator can open it from the outside. There is no way to lock it such the people on the inside cannot get out.

**Q: Funciona con Alexa ?**
A: No.  La cerradura no e conecta a Internet, por lo wrote no d puede operar remotamente.  La cerradura se bloquea sola 10 seg después de abierta,  por lo que no hay riesgo de que incuestionable bloquear la puerta de la casa. La cerradura tiene 4 formas de apertura, huellas,  codigos, proximidad con NFC CARDS y apertura con llave física cuya cerradura se encuentra muy bien oculta bajo el enchapado.

**Q: what app is using for this lock ?**
A: TT Lock App. I have this exact lock and have this app downloaded

### ⭐ Fancy but unreliable. Old fashioned keys don't fail.
*by A***0 on May 18, 2025*

Expect to get locked out at the worst possible time. The unit did just that, it's mechanically well made but the electronics have issues, at a casual locking, carring with me no key, nor my cellphone, the lock stopped responding to my fingerprint and to the passcode too. I didn't get a new fingerprint, it's been the same forever. Bateries were alcaline and new. Connecting to a power bank via USB cable made no difference. After about an hour trying get the thing to let me into my place, I had to resort to a hammer and chisel, the lock is well built, but finally I was able to break it open, not without damaging my door in the process. I recommend leaving a spare key hidden somewhere outside just in case you forgot your keychain when you exited. (I guess not under the door mat). I got used to unlocking using my fingerprint or password, but that's exactly what failed on it. The privacy switch in the inside plate was set to general, not privacy, which prevents opening the door, I had tried it in the past and was aware of that feature.
