iulock 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.

So far so good! Excellent lock, easy to install and program and feel very sturdy. I have 6 of these now and no failures!Awesome!

We bought these to prevent the baby from going into the bedrooms. They’re quiet, easy to install, have had no issues operating and they get used a lot. They auto lock and have key code entry but they also have a back up key and charger port in case the batteries die. I would buy these again if something went wrong.

I freaking love my black door knob lock. It comes with two keys. Installment was very simple. I was able to do so solo. I used one tool. Batteries not included. Changing the access codes is very easy. The whole job took me about 25mins. I'm not sure how the app works honestly.

So many things wrong with this lockset I can't even list them all. The latch assembly binds making turning the knob to open it difficult. It comes with rubber washers to seal the round plates that fit against the door (good idea in theory): they are floppy and almost impossible to fit into place; if you had 3 hands it might help. The knobs have a nice textured rubber grip: if and when they wear out they cannot be replaced. With such narrow knobs it is pretty difficult to turn them - without the rubber grips it might be impossible, especially if your hands are sweaty. The buttons are difficult to see unless you stoop. To unlock the door so you can come in and out, say to bring in several bags of groceries, you have to enter a special code. That means to (un)set it to pass-through mode you have to do it from the outside. In fact everything the lock can do has to be done from the outside. During the last half century I have installed dozens and dozens of locksets of many different brands. It usually takes all of fifteen minutes MAX. This took me hours. I thought the reason it was difficult to open was because the latch plate was off a bit (very old house). Not the problem. Oh, the wooden stop the door closes against needed to be removed and put back on to accommodate the door because it has warped a wee bit. That wasn't the problem. All in all I spent hours trying to get it installed. Programming: in order to make any changes you have to enter the master code first. Good luck finding it. It is nowhere that I could find in the instructions. Turns out it is in a VERY small box with TINY print on one of the flaps on the box it came in. I found it by accident. Just in case you're crazy enough to buy this thing the master code is 123456. The keys that come with the lockets are cheap and feel like they're going to break off when you use them (you'll need to have them so you can get in while you're looking for the master code or adjusting the door frame so you'll need to plan a trip to a hardware store/locksmith to get something solid made for you. If you like punishment this is the lockset for you. If your tastes are less extreme avoid this thing like the plague.

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.

I bought this for the bathroom on my small business cafe. My cafe is in a vacation beach town and I was having problems with non patrons coming in and defecating on the floor and other things. I installed this and programmed my pos to print the code on the bottom of all receipts so that only my patrons know the code. It works great and my patrons love it. The problem is that this lock can't work alone. I had to install a slide lock on the inside of the door so that whenever someone is inside other patrons don't walk in on them. This problem can easily be alleviated with a simple button on the center of the inside door handle to disable the keypad whenever someone is inside. Other than that this is perfect. It was really easy to install and program, took me less than 10 minutes and the keypad even lights up. I love it and if the need arises I will buy another one.

Easy installation and use, great set of options to configure, also feels sturdy. For indoors the lock works really well, haven't proved on outdoors. 2 Keys included and works just fine. Size feels more on the big side but between the limits of the size of a normal knob. Good value for money. Haven't tested app connection and settings.

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

Buena calidad y me funciona super bien la recomiendo ampliamente.
