Important Notes
This smart lock is intended for use on interior or exterior doors depending on installation requirements and environmental conditions. Before purchasing, confirm that your door type and thickness meet compatibility standards to ensure proper fit and function. Custom access codes require the Sifely Gateway device to be generated remotely; without it, these codes must be created manually through the physical lock interface. Always keep an eye on battery levels and consider periodic checks to avoid unexpected shutdowns. Review all included components and follow the provided setup instructions carefully to guarantee a smooth installation process.

Nice sleek-looking smart lock with many options that works well
I waited for about 3 months of use before posting. Occasionally I will get a “failure” to read my fingerprint which takes only a couple seconds to try again and open. The fingerprint reader on my phone fails more often. I also tried to lengthen the duration before it locks but it still seems to do it within a matter of seconds after unlocking. But all in all, it works very reliably and looks sleek and high quality. The remainder of this was written immediately following installation.Installation was very easy. I chose to keep my existing strike plate on the door frame because the screw holes on the provided strike plate were spaced a little further apart than the existing holes.The rubber bumper on the front (keypad) side of the lock looks off-center to me despite several attempts to re-position and re-screw the unit. It also does not lie flush against my door on the back (battery) side. However, I can’t say for sure whether these are issues with the lock or if my door is not perfect to begin with.There is one aspect of the setup process which I found irritating. For adding key fobs, passcodes, fingerprints I would get an “operation failed” message every time if I didn’t first touch the keypad a couple times to “wake it up”. I have installed a number of other smart home devices and found this to be unusually cumbersome and not intuitive to the user compared to other setups. However, this inconvenience is only relevant to initial setup, which is fairly quick to work through if you know these extra touches are necessary.It also was not intuitive which skill to enable in the Alexa app for voice control. The skill name is not stated in the instructions in the box, nor the instructions in the app. Following the QR code for FAQs from the instructions I found a video instruction that shows the skill is called ScienerSmart.I was surprised by how large/bulky the key fobs are. I expected them to be roughly the size of one of those little store loyalty cards that you can put on your keychain, with a little more thickness to it. See picture for size. It is quite large compared to anything else on my keychain.Also, in the app my gateway connection with my lock shows “weak”. My gateway is in a room which is right next to the door. So if you plan to have your gateway located a considerable distance away from your door, the connection strength may not be adequate.I have used the physical key, key fobs, pin code, and fingerprint for entry. All are acceptable, but fingerprint is my preference (prefer not to dig out my keys for the key fob or physical key, and pin code takes a little more time to type in).

Works well, easy installation
Iâve had this lock installed for over a year. The installation, with the included directions, was not too hard. Had to align the strike plate on the door sale, but that was the only issue in the installation. During the year Iâve had the lock installed, it has worked well in both summer and winter months. The batteries actually did last just over a year, which really surprised me. With all of the traffic going in and out of my garage door where I installed this lock I didnât think the batteries could possibly last year.I very much enjoy the feature of autolock on the door, and Iâve had no problem at all with the fingerprint recognition. Definitely recommend this product.

First one broke, but I still consider this 4 stars.
I went through several thumb-reader locks after I build my she shed. I didn’t want to have to deal with a key for a building in my back yard, but I wanted to keep it secure. I think I went through two or three different locks before I found this one. It is very easy to install and add thumbs, fobs, and codes.I believe I bought the first one about a year ago. It had issues reading thumbs when it rained or if the person’s hands were wet. Also, on random occasions it didn’t work. I figured that out, but the other two people who use the building didn’t. That lead to some frustration. Someone couldn’t get in after several attempts and pulled on the handle hard. The sensor never worked again. So, I purchased the same lock again. I feel like they’ve made some improvement. Although, I think they raised the price, it seems like the thumb reader is better. I have not had any issues getting in with this new lock. The person who broke the first lock will be the true test. My mother also has issues getting in, but I think she slides her thumb a little when she tries to use it. It’s really not a difficult process. I don’t know why these people have such a hard time. In any case, the lock comes with two fobs, keys and a way to add codes. I can also unlock it remotely.I recommend this lock 100%. I think the price is kind of high though.

Superb quality, no negatives so far. Smart Lock X
I just installed this lock (X series) on my front door and so far I’m very happy with it. The lock exudes quality; it’s heavy and feels exceptionally well-made, much sturdier than my old Schlage. The installation was a breeze, no different from installing your regular mechanical lock. There’s just one extra step of connecting the wires. If you are replacing your old lock, like I did, this one will slide right into place with no problems.Took me a little over 10 min. The lock comes with everything you’ll need to install and start using it right away: 2 key fobs, a pair of emergency keys and all the hardware neatly bagged and labelled. They took great pains to provide exhaustive install instructions both printed and video. They even put a QR code sticker on the inside half of the lock which takes you to the install video on their website. The support is stellar; I had a question about the app and was chatting with a support technician (thank you, Angelica!) within a couple of minutes, if that. Incidentally, there are two android Sifely apps on Play, Sifely Smart Lock and Sifely MJRHOME. You can use both, and both concurrently if you wish, but they recommend the Smart Lock over MJRHOME because it’s newer one of the two. The locking/unlocking is very smooth and self-explanatory, although they provide detailed instructions on that as well. I tried all methods and all worked without a hitch. I also got the optional gateway which I very much like. The setup and pairing were smooth and easy, everything just works out of the box, fingers crossed. Overall, a quality product, exceptionally well supported. Highly recommend
