Secure, Smart, and Easy to Use
I’m very happy with this smart lock! Installation was simple, the fingerprint reader works quickly, and having multiple access options makes it very convenient. It feels sturdy, looks modern, and gives me extra peace of mind knowing my home is secure. Great value for the price! ⭐⭐⭐⭐⭐🔐✨

The Only Smart Lock I Trust – Bought Multiple Times!
I’ve bought this smart lock multiple times because it’s reliable and built to last. I’ve been using it for years without any issues. I have several installed at my home and another property, and I love managing them all from one app. Installation is easy, and the quality is excellent. Highly recommend!

If you can think of something you want them to do they will do it.
This is my 4th lock I’ve bought now and they have all been perfect. Installation is easy and with the G2 interface I also bought recently they are all connected to Alexia now. This is a great idea and I’m able to program them all to work with one fob. They are all programmed with my phone with an easy to understand app. The tech support I used has been top notch. I highly recommend these to anyone looking to upgrade. Great quality.

Good but doesn’t bring the gateway must buy separately/ BT Only
Great price initially until you find out that you need to cough up another 40 to 50 dollars additionally if you want to get most important features like unlocking your door when you are not home for someone else or to use Google home or Alexa because you need to buy the gateway. It only works though Bluetooth until you buy the gateway which will only let you open the door while you are at some distance of the door. So add an additional 50 bucks with the price of sale. I wish they would have been clear on this before I purchased but beside this it it easy to install and it has been working as intended. I am waiting for the gateway to be mailed to me so I am not sure how will the lock works when I add this bit I am sure it will also work as intended.

I wish there was a 6th star. Honestly one of the best products I've gotten on Amazon.
For reference I had Lowe's Iris before it folded, I now have Samsung Smart-things and Amazon Alexa. My house is pretty smart. I've got devices galore from lots of different generations and brands. I have the Schlage Connected Smart Keypad Z-Wave Lever. I'm pretty used to the various challenges of working with equipment like this. In all of my time doing stuff like this I have never found a single item that made me say yes like Meg Ryan in When Harry Met Sally, until now. The order. I generally lean towards sold and fulfilled by Amazon, but the steep review curve for 5 stars and the acceptable window of 3 to 5 days even though I was ordering in the wee hours of a Sunday morning was acceptable, if it was as good as people said. I got it in 2 days after the first day a person could have seen it. I have no gripes there. Amazon level of delivery and that really is the gold standard today. yes... The package. It arrived and the first thing I noticed was that it was HEAVY. Like, is this shrink wrapped bricks? Is it a slab of lead, DU? A brief shake indicated that there was only the tiniest of jingles inside it. Now I was intrigued. I opened the package which was designed and implemented like it held high end scientific devices with everything in its own perfectly sized recessed pocket in the high density closed cell foam. Nested packages were as individualized as made sense. Screws separated by stage of install and door configuration. Stick on protection for any surface of the parts that you wouldn't want scratched. Physically, the shipment, the packaging, and all of the pieces were perfect. Yes... The install. It was much easier than the Schlage. Hard to read instructions, NOPE, super easy to follow video with shots done from angles that make sense for that stage. They even include a QR code if you don't feel like typing the supplied URL. It was so easy and smooth that I really can't say anything about it. If you have a Phillips head screwdriver and thumbs you can do this. Heck, you may even be able to do it without thumbs. Test it once it's installed and you're done. YES... Setup. Now I thought, the real nightmare probably begins. For comparison, with the Schlage, to program anything you really need the home automation side. With Lowe's Iris it was bearable but usually if I wanted to push changes to it I had to demount it and walk it over closer to the hub. It frequently required multiple attempts and sometimes ended up in a worse configuration as it wiped ones I wanted to keep and didn't load ones I did. Smart-things is even worse. Third party IDEs to interface and cobbled together rats nests of code. I use this part to do this, but that part to do that, this one only runs in Classic, that one runs in the new version unless you want to do this other thing then you have to run in classic... That's not the case here. Download one easy to find App from the app store. It's the only one and it's obvious. Again there's a video along with another QR code to get to it. I must confess that I didn't watch it. I opened the App. Login or Register? I guess register. Yup. Phone number, uh huh. SMS code came in, yup. Touch the knob to put it in pairing mode, ok. Oh it's paired and done and I'm in? That's pretty straight forward. Ohhhh... Configuration. Let's see what we've got here. Plainly legible and easily navigable? Pleasantly surprising, clean and clear. I'm tingly. Ok, I see pass codes lets check that out. Standard 3 dot drop down menu add, clear, etc. Add. Permanent. Wow that was crazy intuitive. Finger prints? I could go on, but seriously coming from other systems I can say that it is literally the most clean and intuitive FUNCTIONAL UI I have ever worked with. EVERYTHING is where and how you would think it should be. Everything that can be done with it is simple to implement with explanations available where you might need it, voice prompts, etc... YES YES YES YES!!!! In short, I love it. If you are looking to smarten up your entry control at a good price with no hassle, then you should have what he's having, Sifely.

Great lock, very convenient, and great customer service
We got these locks initially for a second home we plan to Airbnb when we're not there, 2 of them to cover front and back doors. The ability to easily add and remove temporary access codes from anywhere will make it much easier to handle guests. But once we had them, we liked them so much we got two more for our main house. We love being able to get in with a simple fingerprint scan, much easier even than other combination electronic locks if you're carrying heavy groceries or similar, and we never have to worry about carrying keys. The fingerprint reader is also fast, and much more reliable than my phone. We love the flexibility to issue codes to let a friend or cat-sitter in without giving them permanent access. And we love that we don't have to worry about forgetting to lock the door behind us — Sifely does that for us. Then there's the customer service — it's only when something goes wrong that you have to deal with this, but it's a good test of a company. We bought 4 of these locks, and had a problem with just one of them. It would say it was unlocked when we put in the code or our fingerprint, but we still couldn't open the door. Amazon's customer service couldn't handle this for us — they could send us a new lock, but we had to get the door open to replace it. Sifely's customer service reimbursed the cost of a locksmith to open the door (allowing us to change out the lock) AND sent us a replacement lock. The replacement works perfectly. I don't think this problem is common, but it's good to know that if things really do go wrong, Sifely still has your back. The only caveat is that changing/adding codes or fingerprints requires Bluetooth access to the lock if you only own this item (i.e. you have to be physically present to do it.) If you want to be able to add/change these from anywhere, which we need for the Airbnb place but not for the main home, you'll have to buy a separate Sifely "Gateway" to do it. Luckily, it's not too expensive, at roughly $40 on sale. One gateway can support several locks, in reasonably close range.

Great product and outstanding customer service.
This is a great product! The build quality and packaging is superb, and the lock looks very smart. It's packed with features that are really useful, and make life much easier, especially with the WiFi hub (bought separately) that allows me to control the lock from anywhere in the world! However, after being in use for just over a year the electronics developed some random faults, not affecting the security of the lock, but nevertheless concerning. I messaged Sifely on their helpline, and received a response within minutes. This started a process that ended with them sending me a new lock. Absolutely outstanding customer service. I'm happy to report the new lock is now installed and faultless, and I'll keep my fingers crossed that is stays that way. As a result, I'm still a very happy owner of a lovely piece of security equipment, and happy to give Sifely another 5 star review.

Fingerprint is unreliable, features are very limited, good for basic needs or on a budget - I own 6
I bought this precisely for the fingerprint reader aspect, and found myself greatly disappointed. I had used a Lockly in the past, and that is a much better system, but also costs 5 times as much. I am using these locks in a Church. I have found the fingerprint access to be unreliable. And reliability is an important part of a lock. Sometimes the fingerprint access will work, other times it will not. I use these to lock certain areas of a Church property. I have parishioners and staff who need access to certain areas, but I want to limit their access to specified times. I specifically wanted the fingerprint access, as that cannot easily be shared (people can share passcodes, keys, etc. much easier than they can share their finger/thumb). Unfortunately, the fingerprint reader does not do a good job remembering people's prints. Today, for example, I could not enter a door that I have 3 fingerprints set up on. It's a door I don't use that often (maybe once a month). None of my fingerprints worked anymore. Fortunately, as the admin, I have other ways to unlock it. But I have had instances where people could not access an area with their fingerprint. This meant they had to call me and I had to give them my passcode, and then later change passcodes on all my devices (I have 6 of these locks and two of another Sifely model). The fobs / access codes, and eKeys all work well, and I have not had many issues. Also the app features are very limited, and some quirks A few examples: When creating schedules - you cannot give someone a truly custom passcode. You can give them passcodes that work on a particular day, workdays or weekends. But you cannot, for example, give them a code that works on Tuesdays and Thursdays. Nor can you give them a code that works from 9am-1pm on Mondays, and 5pm-9pm on Tuesdays. If you want to do that you'd have to give them a new code for each shift. Also, when setting up a new user with a passcode, you have to let the app generate a passcode. Then if you want to customize the Passcode you first have to use the generated passcode on the lock (at least one time). If you don't, you will get an error everytime you try to change the code. I'd prefer if I could simply create a user, and let them choose their passcode on setup, bypassing the need to generate a random code, use that random code, and then change it to the user-requested code. These seem like they should be easy enough to fix with a software update. But I would not hold out for that. I am not sure if the Gateway offers more customization. I am thinking of getting one if they go on sale to test it out. But Gateways add another device. On the plus side, the battery life has been really good. On the locks I use daily, I have been using them for over 3 months, and they are still running on the initial 4 AA Rayovac (not exactly brand name) batteries that I installed in them). I find the rechargeable batteries (which I put in a few) seem to need replacing / recharging every 2 months. In all honestly, wish I had the budget to afford another Lockley rather than an Sifely. You do get what you pay for.

Good but a big issue
REVIEWED AT MAY 2024. I bought another similar from the "brother brand" and noticed it has the same wrong behavior, moving the internal lever upwards makes impossible to open it from outside, it accepts the fingerprint or IC card but never moves the latch. To me, it is a faulty design. OIRGINAL COMMENT: Very good characteristics and very solid materials. The installation is done in a very short time, it is really easy. However, I noticed that moving the internal handle up, i.e. contrary to the direction to open and move the latch, the system is not available to open at all, neither using fingerprints, administration code, electronic keys, etc. The only way to open it is to use the physical key provided or if it opened from inside. This is really weird to me. It is not good at all for housing rentals (such as Airbnb). Imagine a guest who involuntarily moves the handle up before leaving, he will never be able to enter again!!! S/he will have to call the administrator to go (probably travel from far) to open the door. This is even worse when the intelligent lock is intended to the main door of a building, where there are several apartments, the involuntary handle movement will make impossible for all tenants to enter the building and they have to call and wait for the administrator to bring the physical key to open the main door ... how annoying and shocking it can be whether this happens in the middle of the night. The support service that is really good and responsive, told me that it could be a defective factory lock and offered me to replace it, however, I am living in Japan and this lock was a kind of US import article, therefore, it was impossible to return it or receive a new one from factory. Fortunately, Amazon's return window was still open and I could return this defective lock. I hope to find another smart lock that has the same characteristics like this, robust enough but fault free.

It works
Installation took longer than anticipated as our door didn’t have a big enough hole to fit everything attached to the lock so we’ve had to cut a bigger hole. Once everything’s screwed in place, setting up everything on the app was really easy (passcode, fingerprint, card). So far so good, haven’t had any problems locking/unlocking. One thing I wasn’t sure about was how to lock the door from outside without using my phone and it turns out that it locks automatically after 5 seconds (default) of the door being closed - can be changed to longer/shorter delay. Fingerprint is very convenient and is the one I use the most. Phone, passcode and access card as back up.

Superb customer service
At last a product that eliminates the need for front door keys. An issue did arise with the handle that Sifely Support Team promptly sorted for me with little fuss. Delighted with the quality of the lock and ease of use.

Almost perfect
The lock is pretty straight forward to install in a wood door. If you're going to use it in a uPVC door, you'll need to drill extra holes etc so be sure it's compatible with your door first. The locks' app functionality is adequate for most needs and does what it says in the documentation. I haven't and won't use a gateway for cloud connectivity as it's too much of a security risk so I can't comment on that functionality. The the one thing I've found so far that really lets it down is the built in speaker, in the app, even on 'volume high', it sounds like a really cheap and nasty piezo speaker and it's very very hard to hear/understand what it's saying.
