Review: Best door lock all the way through - The palm scanner is fast and accurate. It recognizes registered palms in about a second and unlocks smoothly. I have tested it in different lighting conditions and temperatures and it has been consistent. No false rejections, no letting in strangers. It knows who is who and responds accordingly. Beyond the palm feature, it has all the standard smart lock capabilities. Keypad codes, fingerprint reader, app control, temporary access for guests. Multiple ways to get in means flexibility for different situations. The palm scanner is the headline feature but having backup options is practical. Build quality is solid and the lock feels secure. This is not some flimsy gadget pretending to be security hardware. It looks and feels like a serious lock that happens to have futuristic tech built in. The installation fit my standard door prep without modification. The app integration works well for remote monitoring and access management. See who comes and goes, create and revoke access codes, check lock status from anywhere. All the smart features you would expect from a premium smart lock in 2026. For anyone wanting to upgrade their door security with something that feels cutting edge while actually being practical, this delivers. The palm recognition is not just a party trick. It is genuinely useful and works every time. Welcome to the future of home entry.
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.

*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!
