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)

We are loving this door knob! We installed it for a barn door, it was quick & easy. We put in codes, fingerprints, and set up the fobs quickly. It was very user friendly. I love having multiple pass keys to open the door Becuase we have clients that will use it. They get their own key or passcode. Great product.

Bought and install successfuly. Very easy to install, because of marking on every packing of screw and easy to understand manual. Smartlock it self work very nice, there is no issue. Great product. Gonna buy more

I am so impressed with this lock. I have been looking for similar item with many options for a long time until I found this. This lock has so many options for locking and unlocking the door, it is impossible to use all of it. The reason I need this lock was to give other entry into the house in case of emergency as well as grant access when we are not home. This met all my needs and then some. I was definitely a buy when I saw the price. Very easy to install and easy to use. Great

This is a rebrand of the Sifely Model S which is usually a little bit more expensive. INSTALLATION: It was easy when replacing an existing door knob. Phillips screwdriver is all you’ll need. See my design note though. FEATURES: The fingerprint, key, access cards and passcode work perfectly. App is actually the Sifely app which is basic and easy to use. CONNECTIVITY: If you have trouble connecting to Bluetooth, be sure to go into your phone settings and activate Bluetooth the Sifely app in the application settings . Otherwise be prepared for frustration. You’re welcome :) DESIGN: Pro’s: Narrow width: only 2 3/4 inches wide, which was critical to my application. Most other products I searched for much wider which would not have obstructed the door frame. Con: I would have gave this five stars except that two of the mounting screws on the inside of the lock are short too short. They tell you in the instructions that they know about this issue and advise you to contact a customer service or go to your local hardware store to get the right side screws, which they will reimburse you for. You can however temporarily complete the installation without those two screws but it’s just kind of annoying. VALUE: Over all it’s a really great lock for the price. If my opinion changes, I will update. I expect this the last few years.

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.

I am very happy with this lock. The biometric feature lets me add family members that don't live with me, as well as being able to unlock the door through the app on my phone in addition to generating a one-time passcode if needed. I had someone help with the initial installation as boring holes through an existing doorframe just wasn't part of my skillset. I had the lock for a year and a few months before it started having issues; it gave a notification that the batteries were low, so I replaced them, and within 2 days they were low again. I used the same batteries on another device that worked fine, but in any case, I bought more expensive batteries and got the same result. I contacted Sifely customer service and they were terrific. I wasn't sure if my unit was even still under warranty and they never made a hassle about it--asked me for some additional info, then my order number from Amazon, and I received a new lock for free the next day. Installing it was a breeze and the company followed up with me to make sure everything was working ok. You really can't ask for better customer service. As to the lock itself, my only complaint is that the biometric sensor doesn't work well when there's moisture in the air (my door is recessed and covered by a screen door, so it's not getting soaking wet). Nevertheless, the keypad works in wet weather and that's all I need. Highly recommend for the price and convenience.

Easy installation and very easy set up. Really liked this product and has got an amazingly competitive price. I highly recommend this product.

After only 2 months, the fingerprint stopped working and locking mechanism failed to unlock. We've been left outside several times as none of the 5 different ways to get inside (not even the physical key) worked to unlock the door. Useless and a waste of money.
