Keypad & Key Smart Door Lock, 50 User Codes, Waterproof, Auto Lock - Matte Black

Being used on interior door in temperature controlled environment. Cannot comment on extremes of temperature. Instructions for install and all other functions were easy to follow. NOTE: I have intermediate skills in construction, computers and electronics. My purchased security knob was put on a door that had already had the holes cut for a door knob and was replacing an existing knob. Had to do a bit of chiseling to fit latch plate as it was bigger than my old plate, but, my old latch plate would have worked. Got the silver colored knob. Old one was brass. So didn’t really match the old latch plate. Was easy to chip out with a sharp chisel and steady hand. Did a dry fit first and trace around new latch plate where the jam needed to be cut. Easy Peazy. My favorite feature is how it keeps prying eyes from learning your code by allowing you to punch in up to 41 other numbers to disguise your code. It works as long as you punch your code in the proper order somewhere in that series. Which makes using a shorter passcode less risky. You get to program your own passcodes and they can be basically any length up to a ridiculously long one. Make sure you change the master immediately though. Can also have different codes for different people. There is an app for tracking but I generally do not use apps for things like this for personal security reasons. So cannot speak to app functionality. Knob has the ability to use a key and that has a separate mechanical mechanism. Comes with two standard style keys. Both worked and mechanism was well made. Have not yet tried the USB C function to unlock when batteries die. Opens fine from inside of room because interior knob is not tied to the electronic locking function. Feels very heavy duty. Will be used infrequently. But will update this review if needed in the future. Am considering getting another for exterior door. Am very pleased with this security knob. It is well thought out and the functions I have tried have all worked well.

This is so nice! I dont have to worry about forgetting my key anymore. The installation was very easy and straight forward and programming it with a new code was very simple and basic. The quality is nice and does a great job. I am very happy with this purchase. We'll worth the money!

Easy to install, program, and to use. I installed several of these as interior locks to prevent curious children from getting into places they shouldn't be. These are life savers and I'm so glad they're available at such a good price.

Love these cameras! Not only do they work amazing but are super easy to put and to get all set up on your phone and camera in WiFi.

The overall aesthetics, design, and function of this knob set are all excellent. The bolt, locking, and security attributes all seem both precision and heavy duty. The setup or “programming” of passcodes is simple - and easily implemented. There were only 2 “curiosities” I personally encountered. Since I was interested only in a fast installation requiring no advanced features, I did not track down the further information to answer my questions. So for what it is worth… I found the two (knob skirt flange to door surface) rubber sealing gaskets (inner and outer) to be a PITA to install, so they lay perfectly “flat”. On each seal, there is a flat “smooth” side - and its other side has a slight groove (or “track”) in them - which I “assumed” faces the knob, allowing its perimeter edge to “ride in it” - creating a seal between it and the door surface. The assembly drawing provided is not specific enough in detail to confirm or contradict this assertion. However, my best effort to hold the seal in proper positioning - with that track to flange relationship - (to remain perfectly in place around the entire circumference) while tightening the mounting screws - failed. And although there is a continuous seal of the rubber around the knob skirt, it is not uniformly flat and evenly spaced in its width around the flanges, in appearance. This was the case both on the interior and exterior surfaces. Therefore it may be that the seal should be inverted - such that its smooth side faces the knob, while the side with the channel mates to the door surface. My other unsolved mystery was in a failed attempt to successfully program a time period of “delaying the automatic re-locking after an unlock” (using my code) - was successfully achieved. I may be misunderstanding the feature description. But In following the sequence written in the instructions, the lock always indicated an error (red) before I even completed the sequence of codes to be inputted. So setting aside at least one of the fancy features (that I never considered anyway until I read the instructions) this is a very nice knob set. Its materials, design, feel, installation, and security all seem to be of very high quality and never hint that the unit (like most all items now in our market) is made in China. I do recommend this model for anyone wanting this feature set in a door knob that adequately secures your home, yet allows simple passcode access to those granted via the correct code.

Works as well as shown. No nonsense product. Easy to install. The directions are idiot proof. Check the existing holes if replacing a knob.

Fonction toujours aussi bien après 6 mois ! Elle a passer a traver le froid de l hiver québécois

Tengo pocos días de haberla instalado y hasta ahora todo muy bien , las instrucciones son muy claras no tuve problemas .

Llegó en el tiempo programado, en excelentes condiciones. Se ve de buena calidad. Aún no se instala por lo que no puedo opinar del funcionamiento

need help because for two locks I was missing the rubber grip. Can you send it to me?
