Review: UPDATE: Turned out GREAT! You *CAN* duplicate keys and it offers so much smarts! - This product turned out to be ***really impressive**** and great! It's a unique marvel of multiple products in one device: smart lock with keypad, palm reading, physical key, connected doorbell, digital peephole AND security camera with AI. If you struggle to record your hands, I have a suggestion. See video (uploaded low res for privacy). Start with your fingers on the sensor at the same angle of the palm reader (top of device) and slowly raise your hand while keeping the same angle vs the reader. At some point it will register/recognize it. This process became super simple for the whole family to register all hands. At the location it recognizes the palm you can then make a mark on the door frame with a pencil to help you remember the exact location and angle to use next time. Simple and easy. Also, I read information on the product page, and some reviews likely repeating the page info, that you cannot duplicate the keys "for security reasons". ***BUT*** it turns out you can copy the keys as I did at the local hardware store, nothing different to other keys out there. This may seem like an issue but for us it was crucial to have the reassurance that we can each have a physical key to open the lock in an emergency if the battery or motor fails (it hasn't). So yes you can easily copy the keys (they include 2 with the device). The smart notifications detecting people at the door and recordings you can watch from anywhere and the autolock, state update and temporal passwords are already worth the price. On my first review, I was distressed that it required calling customer support to get the round faceplate to install on the door and that the customer support was not easy to reach. However customer support did reach out and did all they could to help me get the round faceplates quickly. Kudos to the eufy team! I encourage eufy to improve the product and communication in a number ow ways to make it even more awesome: Have better information on keys being able to be duplicated if needed, nothing to fear as every other similar lock out there will let you do that and this is an asset that could turn customers away fearing only 2 keys are included. Also, try to include all the right hardware in the box to avoid the issue of extra calls. Finally better support training to resolve and escalate things quickly. Overall, a great impressive product and team and I look forward to keeping using this device and learning more about the ways Eufy innovates in this space.
Review: Impressive and great features - Impressed with all the options and features. UI Is a bit confusing tho and I do agree that the hands/vein technology is difficult to get to work. I’m gonna try creating multiple versions of my hands to see if that’ll improve things like I’ve done with the thumbprint one. Actually wishing I had the fingerprint one still. The video mechanism works great and you can choose different lengths to film, which I really like. I did feel that the battery could’ve lasted a bit longer. It lasted about a month before it needed recharging them but the four AA batteries held fine while it was being charged. This was with a lot of people coming in and out though. Np installing to door (although had my handyman do it). NOTE: after putting it together it will have u press a button in the back wheee the battery is and if u already put the cover on np bc it’s super easy to take off. I did have to try connecting a couple of times. If you have issues with this part and it talks about router settings go to your Internet provider settings online or app and change signal to 2.4 only from dual band (2.4 and 5.0) temporarily and then u won’t have a problem.

### ⭐⭐⭐⭐⭐ Better than I had imagined!
*by C***S on January 20, 2026*

I was able to easily install myself. The app works very well and I had no issue connecting to wifi and getting it to work. I haven’t had any issues with the palm reader so far, which is a really convenient option. The screen/camera is also very clear and works well. I’m very happy I decided to go with this smart lock!
