Keyless Entry Fingerprint Digital Smart Lock with Handle & Keypad: Electronic/Electric Lock with Code, App Control Biometric Deadbolt Door Knob for Front, Interior, Exterior & Bedroom Door (Black)

I love how this product comes with the screws all packaged in separate bags each labeled with the step number they are used in! It was a little tricky here and there but just being patient in reading the instructions made it easy. Great details in the instructions including mistakes to watch out for. And there's even a step by step video to follow. As it turned out, the hardest part was figuring out how to get the old door knob off!

Purchased this to replace our front door lock. Since our family usually uses the garage to enter/exit the house, we often forget to bring our keys. I wanted to have an alternative entrance (e.g. in case of a power outage or when I got out for a run).Product research was a bit confusing because there are similar looking locks branded from Sifely, Dermum, and samtechT sold by different 3rd party stores. My understanding is that they are minor rebrands of the same 2 lock models and all use the Sifely app. The older model comes in a brown box, and the newer one comes in a blue box. I received a blue box with a check mark indicating it is a black model. It comes with 2 normal looking physical keys and 2 white, unmarked key fobs. The only indication that it is a Dermum brand is on a small label on the blue box and instruction printouts.It look about 15 mins to replace the lock. The only thing I supplied was a screwdriver. I suggest watching the installation video (https://dermumstore.com/pages/dermum-s-smart-lock-tutorial) before and during install. It was compatible with the existing strike plate so I left that alone. Once it is installed, it felt very sturdy (doesn't wiggle or anything) and looked very modern/minimalistic with the black styling.You MUST pair the lock to a smartphone because anyone can do it without needing physical access to the inside (i.e. there's no initial pair button) until a Sifely account takes ownership of it. Afterwards, ownership can only be reset by using the reset button inside the battery panel. Speaking of battery, I used 4 high-capacity Eneloops. They started at 65% (not sure if its due to the lower voltage of the rechargeable battery or the state of the batteries I was using) but its stayed at that value for the past week.We love the multitude of ways of lock access. You can use passcodes (generated or user defined), e-keys (normal or admin access given to other Sifely accounts), fobs, and finger prints. Passcodes can be one time. Other digital access can be recurring (e.g. only during daylight hours on certain days of the week). You can also view the access records of the lock from the app. The only thing you can't control is the physical key and should work even if there's no power. Fingerprint access is really convenient but could have better success rate. It works great for me but a bit touchy for my wife. We use multiple fingerprints to help (e.g. "Foo Thumb" and "Foo Thumb 2") plus passcode backup. There is a physical privacy slider that will block everything except physical key and admin digital access. The lock auto relocks after a few seconds (up to as long as you want). There is no physical slider/button to leave it unlocked (e.g. contractors going in and out of the house) but you can enable passage mode in the app to do that.We love the lock and will probably replace our side door with it as well. It has the ability to mirror settings between locks so it should make setting that up easier.Update: Correct some spellings and wording. Still working well after 2 weeks.

Working great, instructions great

Installed in the front door of our busy household of 6. After a few months the shaft started to loosen resulting in the handles having play and being somewhat floppy. After 2 years we discarded as the mechanism had worn enough that it would no longer fully retract the striker. As with most lever-type handles the complete assembly tended to tilt over time due to the handle being pressed one way a trillion times.The fingerprint scanner worked very well and we never had a problem with the key code either. The app was intuitive and worked well. I managed to create a few one-time passcodes for folks and that worked great too. Installation was simple. If you could install a regular handle you could also install this one.Mechanically it was a so-so chineseum door handle. Electronically / technologically it was very good.

Lack is excellent does everything we needed it to do. It was very easy to put together and when we had a minor issue programming the fingerprint option we reached out to customer service for the lock, and their response was timely, and it helped us to immediately fix the problem For that we thank them. I would purchase other products from them and would also recommend them to others who are looking for this type of product.

Update -- I bought a second one against my better judgement and it doesn't work. The screws stripped out and it became a huge pain in the ass to uninstall.The problem isn't with the lock itself since the functions (minus the fingerprint reader) works great. The problem is where the override lock button is located. Eventually I'll buy a different lock and move this one somewhere else, but for now it works and is a good price.Override Lock FunctionThere is a tiny switch on the front of the knob on the house side that clicks on and off to allow you to override the other features so no one can enter the house even with a code or fingerprint assigned. However, it is in a terrible spot. If you hold onto the door and shut it as you're leaving the chances of brushing against it and triggering it and locking yourself out are VERY high. Ask me how I know. :)Anyway, if you're careful of that, you can avoid it. The second issue is my dogs have triggered the button twice now as well. It was solved with a dog gate but if you have this in an area where you can't have a dog gate and your dogs can reach the lock, you can be easily locked out.Having a function where you had to press the button down and move it in the opposite direction it was currently set might fix the issue, but I think the answer is to totally move the button to the very bottom of the unit.Fingerprint ReaderSimply does not work. I have tried to register a few different fingers and done it a few different times but it never works after the initial first time setting it up.

Great. You can control it from the app.

The media could not be loaded. I love this product. I'm very excited because I finally have more security at the front door of my house. Installation is very easy, quick, and efficient.
