Just bought a second after 4 years. Lessons to
Just bought a replacement. First one lasted 4 years and one move. Second one fit into previous hardware so didn’t have to change the fittings, that was nice. Beware they really mean it that it should be completely exposed to heavy rain. Get a cover if at exposed sight. That’s how it died at new house, not in a covered area. Lesson learned. Glad to have it working again. Easy to use, love the auto locking so never have to wonder if the front door is locked. We figured for $20 a year over those four years it was worth it knowing our kiddo was never locked out, our guests weren’t walking around with our keys, and our house was alway safe.

You cannot ask more from a smart lock but consider adding a gateway if you need full remote access
I recently purchased this smart lock for my Airbnb property, and I am thoroughly impressed with its performance and features. This lock truly offers everything you could ask for in a smart lock. First and foremost, the fingerprint reader is incredibly responsive and convenient. The ability to generate temporary PINs through the app is a game-changer for managing guest access. This feature alone makes it worth the investment, as it simplifies the check-in process immensely. I specifically needed a lock that had physical keys for easy access in case the battery runs out, and this smart lock delivers on that front as well. Additionally, the card reader is a fantastic bonus that adds another layer of versatility and convenience. One point of confusion for me initially was the need for a gateway to generate PINs remotely and access the lock’s history. Without the gateway, these features are only accessible via Bluetooth when you are close to the door. The gateway acts as a WiFi to Bluetooth bridge, allowing you to send instructions to the lock remotely and view access history in real-time. Once I purchased and synced the gateway, all the remote features I needed were unlocked, making this lock even more powerful and user-friendly. Installation was straightforward, and the lock has a sleek, modern design that looks great on my door. Overall, I am extremely pleased with this smart lock. It offers excellent value for the price and has significantly improved the management of my Airbnb property. If you’re looking for a smart lock with robust features, easy installation, and great aesthetics, I highly recommend this one. Just make sure to get the gateway if you need remote access capabilities.

It works perfectly
Awesome lock so far! Easy installation and a user friendly application, what else can be said. Haven’t used the key fob feature yet since biometric access was my main feature, but I’m actually thinking about purchasing other products from the same line. If I can ask a suggestion for whoever is developing the product, please add a simple door handle with just biometrics and no number pad. This would expand your product line to those who want to have private access to all rooms without the bulkiness of a keypad on every door.

Good looking lock, works quite well, touch screen not very responsive
Bought this lock awhile ago and just got to installing it this weekend. Install took a little over an hour and a half. The instructions for the install are pretty decent and if you have installed a normal lock before, its the same process. Once i got the lock installed it software setup time. Again, the instructions arent too bad and were easy enough for me to follow. The lock needs 4 AA batteries for power and as this is new, im not able to state approx how long i expect them to last. Per Sifely there is a battery back option, which I assume means attaching a portable USB power adaptor to it and letting it sit there. But should batteries fail you have keys. You download the software to your phone, then connect to it via bluetooth and then setup a keycode. Now you have full access to the lock to add any additional pins, fingerprints etc. This lock has multiple methods of locking/unlocking. There is also a setting to have the lock auto lock itself after a set time frame which is adjustable. You can also setup a schedule for when you want it to auto lock itself. Fingerprint - was quite easy to do, same as adding a fingerprint to unlock your phone. You can add multiple fingerprints to it for all family members etc. Tested and worked. Physical key. You pop off a magnetic cover insert key and unlock. The keys arent your normal style key and are rather long and when added to your keychain they are like mini weapons. Tested and worked. Phone App - You can use your phone to lock/unlock as long as you are within Bluetooth Range. (More on that later) Pin Codes - You can assign PIN codes for each family member, a guest (if someone is house/pet sitting) and remove those codes. You can set permanent codes, temp codes time limited codes. You can also setup a PIN code on your phone and then send that to the intended party. I had multiple issues with the front screen not lighting up or being unresponsive so i COULD type in an actual PIN. I had to really tap it multiple times to wake up the screen. Tested and worked, kind of. Keyfob/Card - You get a flat card which you put against the front which will also unlock the door. They are a little bulky when on your keychain but Sifely has an option (Sifely Key Fob with Keychain) to purchase a smaller form factor keyfob that looks better and is less bulky. Card Tested and worked. I ordered the Keyfob so i cant speak to it working or not. If you want to add this to Alexa/Google Home, youll need a Gateway, which Sifely also sells. Sifely Smart Lock Wi-Fi Gateway (Model Name: G2). What this does is allow you to actually remotely lock/unlock your device and enable Alexa/Google integration so you can use your voice to lock/unlock or add a Routine and actually unlock/lock it from anywhere. I ordered the Gateway so that test is still pending. I really like the Smart Lock. I like all the available methods to lock and unlock it so im not stuck not being able to get in my house if one of them fails or i can use one of the keys if the entire device fails. I would have given it 5 stars if the front panel actually worked consistently but it doesnt.

Pretty good lock
I’ve had many of these locks for years, worked pretty well. First let me say, I use them primarily on building entrances. At first I had water seal problems seemed like one would go out every year about rainy season. Liberal use of sealant fixed that. The only other puzzle, was I couldn’t get the fingerprint detection to work for very long. Put in a print it works about 20 minutes and it would forget it ever existed. Never been able to solve that one. Any ideas?

Extra Security
So far so good! It’s a beautiful piece of hardware. All of the features work just as advertised. I purchased it 6 months before I was able to get it installed so I was afraid it wouldn’t work and I had wasted money, but my fears were subsided. The install video assisted, but the install pamphlet was dead on. All of the features work perfectly. Sometimes, the fingerprint recognition doesn’t immediately acknowledge the “lock” feature (unlock works like a charm), but if you go into the settings you can have it automatically lock the door within the optional seconds you specific. The voice feature will clearly announce the status of the lock. It says it works with Google and Alexa. I have both, but chose to pair it with Google since my Alexa works my cameras and robotic vacuum. I had very little difficulty pairing the lock with my Google and many times when I’m in, I’ll ask Google to manage the door and it lock/unlock without a hiccup. The selling point for me was the remote ability to lock/unlock the door at my discretion for my guests, as well as check the status of the door. You would need to purchase the Sifely gateway for this feature, but you will not be disappointed. It works well with your internet. You can also add authorize passkeys for trusted members so that they may be able to gain access to your home. I have the lock on my garage door. I highly recommend this lock. Update 07/24/24: I got in contact with the Sifely customer care group because the fingerprint option was still malfunctioning. The customer care group immediately decided that they would send a replacement deadbolt lock to replace this one. The Sifely care group was so courteous and attentive to my issue. They remained in constant contact with me even though I was slow to respond. They walked me through troubleshooting measures and ensured me my safety with their product was their only concern. Because of my interaction with the Sifely Customer Care group I highly endorse this product and will buy anything with the Sifely name on it.

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! ⭐⭐⭐⭐⭐🔐✨

Good Overall, But A Few Shortcomings
First, just in case they are dealbreakers for someone, the shortcomings: 1. I bought this in part because it had a Schlage key system. Unfortunately the lock apparently cannot be rekeyed, per an answer I found on the company's website. That means carrying around more keys if you want a non-electronic backup for entry. 2. You can apparently enter as many wrong codes or wrong fingerprints as you like without the lock creating a timeout. It will, however, create a record of the incorrect attempts. As to the unit itself, it offers a number of ways of gaining entry, including a keycode which can be of different lengths, and which unlike some other locks does not let the user know that it is wrong until they hit the # button (more secure). In addition to the keycode, the fingerprint scanner seems to work quickly and well, two near field tags are provided, unlock from the app, and you can apparently connect it to smart systems like Alexa (optional and insecure). You can also buy optional remote controls, which are similar to small garage door openers. It also offers a privacy button you can hit from inside, which turns off all these "smart" ways of operating the lock (traditional keys excluded), presumably intended for while you're home sleeping at night. This privacy button automatically turns off when you exit through the lock. It does have a way of having the lock stay open for a variable amount of time after unlocking (default 5 seconds), and also of scheduling times of day when the lock will stay unlocked. What it doesn't have is a way of unlocking the door at a given time you may want to be going in and out a lot, but for those with fingerprints scanned into the lock that is a minor issue. Unfortunately the instructions are not great, but they are supplemented by the screw packets being labeled for what step the screws are needed. Also, a second set of screws is provided, although not labbled with each step. One minor nice feature is the inside portion has a backer plate which is screwed in place to hold the outside portion in place. That makes installation slightly easier, and is probably a bit more secure. Also the batteries (4 AA) can be replaced without removing a single screw. Overall this is a better keypad lock than the approximately 15 year old Schlage keypad lock which it replaces. This keycode system is much more secure (Schlage may have updated that since I purchased), and the available fingerprint option a nice fast option to have. The only thing I will miss is the ability to just set the lock to unlocked on a whim, and the ability to rekey the lock.

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.

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.

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.

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.
