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 (Silver)

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.

This is a solid door handle and mechanism. The only FYI is to be careful if you remove the small physical key cover. Four tiny magnets hold it in. It's probably hard to lose them, but mine came out, and I pushed them back in; it's all fine. The fingerprint feature works excellently, the app is good, and the push button entry works, too. It is installed on an exterior door to a pool house and, in the summer, is unlocked daily. I would buy it again no problem.

Lock works very well, was very easy to install and setup, whether using touch, fingerprint or the app it works well. Had an issue with the lock months into owning it and customer service was excellent and took care of my issue quickly.

These locks provide multiple methods for unlocking doors, including code entry, fingerprint recognition, smart card usage, smartphone applications, web portal, and physical keys. Users have full control over access permissions, allowing them to assign one or several access methods to individuals as needed. Granting access to one lock does not automatically extend access to all locks in the system; for example, I manage five locks, two of which are exclusively accessible by myself.The auto lock feature, combined with the passthrough setting, enables automated locking after the door is unlocked, with the option to disable this function during designated periods. For instance, our back door utilizes auto lock but remains in passthrough mode from 7am to 9pm so that it does not relock during frequent daytime use.One limitation is the lack of an at-a-glance overview for lock status. Currently, each lock’s status must be individually checked via the smartphone app, web portal, or Alexa integration.Please note: These locks are not waterproof. If installation is required in an exposed location, it is recommended to purchase a keypad cover, which may require modification to accommodate the door handle.

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.
