You can use your phone, or connect you Alexa to lock and unlock door. Finger print works great. It’s easy to add other people. You can set the their own code. And time they can access your house. Highly recommend! Just bought a second one! Love the convenience of using your fringed print!

I have me and my wife with different passwords and our finger print work just perfect. I dont even need to jave my keys to go kn amd out so that’s perfect for me. Sometimes will leave the house close the door and forgot to lock it. Well you can even set the time tou want it to lock and you get a notification when its lock or even when unlock by some one.

Best investment for short term rentals!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love this lock and how easy it is to use & manage. You will have to charge the battery for about 3 hours prior to using, but other than that, the installation was super easy. This lock has been a blessing to my short term rental company, allowing guests to enter properties without having to meet them with a key. Also saves me from having to re-key/ spend money getting keys made as a result of guest losing keys. Just set a code for them and save money and time!

Love this door lock!
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love this door lock! I set installed it myself in about 30 minutes. Love not having to shuffle thru my purse for my keys! Also It's great when we have house guests...we can just give them their own code for as long as they need it and then just delete it...all from the app. So easy to use.

Eufy Security Smart Lock
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.One of the best investments I’ve made. Asides from fingerprint, code and key entry you can now use the app to lock/unlock door when away from home. Fingerprint scanner is very accurate, battery has really good life before needing recharge. Application notifies you when someone attempts to or unlocks door.

Great lock, go for it.

Great quality product with a lot of features, super easy to install it and much more makes of this an amazingly good electronic lock. The finger print reader is really convenience and is working really well since the lock was installed about 1 month ago.

Very good lock
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Very nice look, multiple options to unlock. Fingerprint /Wi-Fi/physical key/keypad/Bluetooth App is easy and clean Looks premium Easy to install Wish the fingerprint push to lock was faster Also wish it had a sensor to tell of the door was open or closed (not only locked and unlocked) A little bit on the pricey side But overall happy with my purchase

Superb smart lock
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love that each user can set up their own numerical code and fingerprint to lock/unlock the door. Perfect for elderly mother to simply use her finger to use the lock. Codes and keys can be challenging at times for her. The app will notify you who is actually using the lock as well. Very easy to setup and use.

Eufy does it again!
||Posted .

I love the eufy cams so i decided to purchase this which while it was on sale. Install and Set up was 20min and synced up perfectly with the added bonus of working with googles voice assistant. Perfect Buy for our home aet up.

Almost perfect
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This smart lock comes with everything you need. Easy to install. Just a screw driver is needed. So many methods by which you can enter the house: Phone app, pin, finger print, and physical key. The auto lock feature is not perfect, it doesnt always work. I would say 90 % of the time it does. I highly recommend. But the company needs to fix this flaw

Impressed by Eufy’s Functionality & Accuracy
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love the eufy lock... It works great. I’ve been able to open and close it using my thumbprint and combination, and haven’t even needed to use the keys provided- which was the goal. I’ve also assigned combinations for several relatives who came to visit, and it’s super convenient. I am impressed- expected glitches, but it’s been great.
