I've had two WiFi Locks by well known companies that failed within the first year and they wouldn't replace their locks as they both only had a 90 day warranty. That made me start looking for a replacement and that's how I came upon Eufy. I read reviews and found that they have a very good reputation. So I decided to plunge and buy. The other two companies required this extensive process for installation. Eufy's installation was so easy it wasn't funny. I set aside an hour to install figuring it might take longer but my installation took less than 30 minutes. I was astounded and integrating with Alexa was a breeze. It literally took a few minutes. All I needed to do was to download the skill and Alexa did the rest. I love being able to check the status of my lock from the Alexa app. And I get notifications if I leave the house and have left the front door unlocked.The other thing I love - I added locking the front door to my evening routine. I tell Alexa Good Night and the living room lights are turned off, Alexa checks to make sure the front door is locked and then my bedroom light is turned off. You gotta love technology!!You want to buy a simple but efficient and reliable lock that works with Alexa, then this is your product.

It was easy to install and sends me a message when someone enters a code or even locks/unlocks manually. It is easy to change codes (I use it in an Airbnb, so I change guest codes often). It notifies you of low batteries, and they are easy to change. 5 min. I love it. I have not used the Alexa integration, so I cannot comment on that.

Everything with this product was first class, from the packaging, through the physical installation, to downloading the app and connecting online. The lock's appearance looks amazing!

Installation was as easy as any deadbolt I've installed. This replaced a previous deadbolt, so I didn't have to drill the hole for access, so removing the old deadbolt and physically installing this one took about 10 minutes. Setting up an account, selecting a pass code, and updating the firmware took 2X as long as physically installing the lock...lol

The deadbolt works flawlessly with the manual manipulation of the lock, using the exterior keypad, and using the app on my smartphone. I also love the fact that I receive an indication on my phone when the lock is opened or closed. It also maintains a log of operations.

No idea how long this will last, but my initial impression is that it's an excellent product, and I couldn't be happier. Two thumbs up!

I purchased this Eufy Smart Deadbolt to replace another one that was missing some key features that I wanted. It was pretty simple to install and connect to the Eufy app.

I really like the instant notifications for app lock/unlock and especially when it's manually done. Also, like the real-time status confirming if door is unlocked/locked. The Google Assistant integration works well but you do need to set up/use a code to confirm before it will take action on the lock. These are some of the features that my prior lock didn't have. The internal WiFi bridge is a plus. I had no issues connecting on a mesh network. Since the inside turn latch is completely plain, I put a small gemstone on it to be able to quickly look and see if door is locked if/when phone isn't nearby to check. One downside I noticed is it does leave fingerprints on the touch pad (reason for 4 stars).

After reading other reviews, I'm hoping to have a better experience and that the lock lasts a long time with no problems.

This lock is a performer! I have installed many smart locks. My favorites have always been Yale and Kwikset. This lock has all of their features and more. This lock is literally less than half the price of the competition with great reliability. The only drawback is that the keys are hard to get duplicates of. That is a good security feature in a way, just don't lose them! The lock even has a USB C port to allow the use of a power supply to give access in case the batteries fail. Installation is super easy and straightforward. The app is seamless and easy to understand. This lock is my new favorite. More expensive models even include a camera. I like Eufy's business model and will definitely be using more of these in the future.

Reviewed in Canada on October 24, 2023
Color: BlackVerified Purchase
Rating: ★★★★★ (5/5)

The eufy Security C210 Smart Lock is a cutting-edge keyless entry door lock that redefines home security. With its 5-in-1 capabilities, built-in WiFi, no bridge requirement, easy installation, touchscreen keypad, and app remote control, this smart lock ensures that your home is safeguarded with convenience and reliability. Here's why I believe this smart lock deserves a glowing review:

5-in-1 Keyless Entry: This smart lock offers multiple ways to access your home, including a touchscreen keypad, smartphone app, fingerprint scanner, physical key, and even voice control (when paired with compatible devices).

Built-in WiFi: The built-in WiFi feature eliminates the need for an additional bridge or hub, simplifying the setup and allowing you to connect the smart lock directly to your home network.

No Bridge Required: With eufy C210, you don't need any extra components or devices. It's a standalone solution that ensures your home security is uncomplicated.

Easy Installation: Installing the C210 is a breeze. It's designed for DIY installation, and the process is straightforward, even for those with limited technical skills.

Touchscreen Keypad: The touchscreen keypad offers a user-friendly interface for entering access codes, enhancing your security and convenience.

App Remote Control: The eufy Security app allows you to control your smart lock remotely. You can lock or unlock your door from anywhere, making it ideal for granting access to guests or service providers.

BHMA Certified: The BHMA certification underscores the smart lock's quality, durability, and security, giving you peace of mind regarding its performance.

Me encanto, súper fácil de poner si tienes la herramienta adecuada, lo único que no me gusto es que no se puede abrir o cerrar por medio de ubicación aunque eso ya es del software de EUfy pero la calidad es muy buena y funcional para todo lo demás. Sería Perfecto si fuera compatible con apple HomeKit y con ubicación

1.0 out of 5 stars No BT unlocking, bad customer service

This lock is advertised as capable of locking/unlocking via BT. This is not true. The customer service I contacted claimed application unlocking is what is meant by BT but it is not BT, it is wifi unlocking and clearly needs a connection to the company server. In other words, one has to be connected to the internet to unlock it from within application.
After I stated this simply fact the agent got disconnected.

I ordered Elanor code door lock before this where i spent 2.5hrs trying to get it to lock properly. It never did. I ordered this lock as a replacement. Instructions were straight forward and i was able to easily install it and program it as well. I didnt need to do any configuration as the motor of the lock is strong. If you ever see this on deal, i highly recommend buying it. Totally worth the money!
