Smart Door Handle Lock with Keypad: Yamiry Fingerprint Smart Knob - Keyless Entry Digital Lock for Front Door - Deadbolt with APP - Generate Passcode Remotely - DIY Installation

Installation was easy. I’m not very handy, but I got it set up in about 20 minutes with just a screwdriver. The instructions were straightforward, and everything fit perfectly on my door. The fingerprint scanner works really well. It recognizes my thumb almost instantly, which is super convenient when my hands are full. I also like having the keypad as a backup, and the numbers light up at night which is a nice touch. Plus, the auto-lock feature is great for those times I forget to lock the door on my way out.

I would give this 10 stars if I could. I installed one on our pantry door a year ago and then needed one for my daughter’s bedroom after they got locked out of their room and the lock broke for their previous lock. I had forgotten how easy it is to install. It took me about 30 minutes to install the lock, power it up, set up their profiles and they each had finger print access and their own password for the same lock. Update on my first purchase. It still works amazing and I have not had to replace the lithium batteries over a year later. The lock also comes with two keys and a key card. You can set up everything after you download the app. You can also lock and unlock it on your phone app. The value is great and the quality also is great. If you need a smart interior door lock with a keypad and smart features this is the only one you will ever need. Can’t recommend it any higher.

I recently installed this electronic deadbolt on my back door and have been very pleased with its performance. The price point is very reasonable compared to other smart locks on the market, offering excellent value.Easy Installation:The setup was surprisingly straightforward - I was able to replace my existing deadbolt in about 20 minutes using just basic tools. The instructions were clear and all necessary parts were included.Reliable Fingerprint Scanner:While some reviews mention issues with the fingerprint recognition, I haven't experienced any problems.Auto-Lock Feature is Game-Changing:The automatic locking function is incredibly convenient. I no longer have to double-check whether I remembered to lock the door - it secures itself after few seconds. This peace of mind is worth the price alone.Important Note About Remote Access:Be aware that without purchasing the separate gateway device, you won't have remote control capabilities via smartphone. This wasn't an issue for me as I'm using it on my back door where I don't need remote access, but front door users may want to factor in- Physical key backup is included for emergenciesFor the price, this smart lock delivers excellent functionality and has significantly improved my daily routine.

This is a very nice lock and appears to be well made. It also works well so far. I left off a star because of a few minor details. I used this to replace an old Kwikset lever lock that had worn out after a decade or so of use. This was easy to install and worked well on my back door which has the deadbolt hole placed a little too close to the doorknob hole where this lock mounts. With the old KW I had to turn the inside unit upside down to make it work but this unit is short enough to fit properly. The fingerprint to open is great and works well although I did have to enter my thumb at 2 different angles and learn that I had to place the finger on it and hold for about a second.The minor details:(1.) There is no easy way to lock the door from the inside. A simple button wired to the main board through the battery connection cable should be incorporated in future designs.(2.) Locking the lock from the outside isn't easy either. You do it by touching and holding the checkmark key. This usually takes two taps on the key holding it the second time when it beeps. If I were writing the firmware for this thing, I would have made the fingerprint sensor toggle the lock. In other words, if the door is locked and a valid print is used, it unlocks. If the door is unlocked and a valid print is used it locks. So, if the manufacturer is reading this, please consider this change to the firmware. It is to me the intuitive way to do things. The auto lock feature is good but not for me. I want to leave the door unlocked until I want it locked. It should be easy to lock the door manually, without the need of the app.(3.) Making it work with Alexa was tricky for me. I bought the bundle with the wi-fi gateway because I wanted to control it remotely and also by voice with my echo devices. I first set the gateway up in the Smart Things (actually Brilliant Smart - Tuya) app which I was already using for other things. and added the lock. Everything appeared to work except Alexa voice control. It replied with a device not responding error even though the lock itself was working through the app. So, I started over and set everything up in the Nice Digi app. That worked except there is no Alexa voice control because Nice Digi doesn't have an Alexa skill. So, I tried a third time by deleting it from the Nice Digi app and again pairing the gateway with the Brilliant Smart-Tuya app. Third time was a charm as it all works now. This just may be an old man issue, but I usually breeze through linking up IOT devices. Maybe Nice Digi should consider writing their own Alexa skill instead of using Smart Life.I do like being able to lock/unlock the door with Alexa voice control as well as being able to control it from anywhere with the Tuya compatible app. So, I recommend buying the bundle with the gateway included. In general, despite my minor issues, I am happy with the purchase so far and expect I will enjoy having the smart upgrade from my old lock. I do hope it lasts as long as that old KW did!
