IU-30 Satin Nickel

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.

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.

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.

This is new, but if it begins to fail, I'll update as needed. Pro: Lock is very nice looking. It's very modern, and sleek. It was easy to follow the step by step instructions to change and add a code. It comes with an app you can use to get temporary codes. It autolocks so you don't have to worry about forgetting to lock your door. It has a rubber grip that makes it easy to open on the inside and the outside of your hands are wet or slippery. The rubber grip is also a godsend since I live in Florida and my house is East facing. I get 6-8 hrs of direct sunlight in the front of the house, and my old door knob would get extremely hot. You can charge the Lock via usb-c if needed, but that is more so the backup battery. Main power comes from AAA batteries. It comes with a template if you need to make the holes, mine fit perfectly in the holes that were already there from my old Lock. Cons: There are no installation instructions. So, if you've never replaced a lock or door knob, you would have to youtube a video or something. I have replaced my locks enough times to know how to do it. And the insides have marking that show which side goes up which made it way easier to install. The batteries were not included. The tiny connector cable was folded on itself so when I needed to thread it thru the middle of the lock to connect it to the power source, I had to use soldering tweezers to get it thru. The cable itself kept bending inside of the lock and would get stuck half way thru. All in all, for the price, I think it is a great lock and would recommend. It took me about 15 mins to install, but that is only due to the cable not wanting to come thru the lock. I am extremely happy with this purchase. It's not perfect, but it is exactly what I wanted/needed. I do need to check and see if the seller sells extra rubber grips due to one of my dogs having severe anxiety and sometimes chewing on the door knob. But that is my issue, not the sellers.

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.

Pros: Bought for a home, hollow core door. Easy to install, set up, and use. Been using it daily for about 6 months with zero technical issues. Quality seems to be there. Cons: if you don’t turn the knob within about 6 seconds of entering the correct code, the knob auto re-locks. Not great when one hand is holding a cup of coffee. Also, this isn’t the most aesthetic door knob I’ve ever seen. When compared to the rest of the brass knobs in my house, this one is kind of like the Melissa McCarthy (The Heat/ Bridesmaids) of door knobs. Slightly bigger, a little hard to handle without using both hands, but once unlocked, a solid choice. Battery life is completely acceptable and I’ve never had a single issue with the lock not working upon entry of the correct code.

I don't usually leave reviews on Amazon but this door knob was very simple to install and works as it should. I thought it would be a hassle put took me 10 minutes to install.

These smart locks are awesome. They are easily programmable in multiple ways making them extremely convenient, whether you want a door that locks every time you exit, remains unlocked until you lock it, or programming guest codes, they are very quick and easy to use. Overall, these locks are a great value for the money!
