eufy Security Smart Lock C210, Keyless Entry Door Lock, Built-in WiFi

I have tried several other smart locks and just love the simplicity of this lock. It just works! Battery lasts long. The app to assign the codes is simple to use and has all the features I need for our short let properties. I also have their video cam, so soon enough I would be entirely over to their ecosystem!

The chrome finish looks elegant and the build quality feels solid. Installation was quick — I got it set up in under 10 minutes. It integrates smoothly with my Eufy doorbell and cameras via HomeBase, and battery replacement is super easy.I also appreciate the backup key option, which gives peace of mind if Wi-Fi or the app ever fails. My only issue is that the passcode unlock feature occasionally doesn't respond well, which can be frustrating. Otherwise, it's been a reliable smart lock overall.

I purchased this for my son. He installed it with no issues and says it works as expected. No complaints.

I purchased the Eufy Smart Lock C210 with high expectations, especially since it was advertised as compatible with Google Home/Google Assistant—a key feature that influenced my buying decision. However, after installation, I quickly realized that this feature does not work (see the picture), despite being prominently promoted on both Eufy’s website and Amazon product page.False Advertising and Unfulfilled Promises:The product description clearly states that this lock works with Google Home, yet after multiple troubleshooting attempts and direct communication with Eufy support, it became evident that this claim was completely misleading. The company even acknowledged this in their responses, confirming that the C210 is not compatible with Google Home, contradicting their own promotional material.Frustrating and Inadequate Customer Support:After reporting the issue to Eufy’s customer support, I expected a reasonable solution—perhaps an exchange for a model that actually includes the advertised functionality. Instead, the only resolution offered was returning the lock, which is completely impractical during freezing winter months when removing a front door lock is not a simple task.Final Verdict – AVOID if Google Home Compatibility is Important:This experience has been incredibly frustrating. I trusted Eufy as a reliable brand, but this situation has demonstrated a lack of commitment to customer satisfaction and a refusal to take full responsibility for misleading consumers.If you are purchasing this lock expecting Google Home compatibility, DO NOT BUY IT. The product does not work as advertised, and Eufy’s support team will not offer a fair resolution.I strongly advise potential buyers to double-check product claims from this brand before making a purchase, as this situation has proven that their marketing materials are not always reliable.Would I buy from Eufy again? Based on this experience, highly unlikely.

I like it, it’s on a door that is not used often and it seems to go through batteries quickly or more than I think it should for not being used often. I would imagine if used on a daily basis I would be changing batteries every couple of weeks !

I installed it myself. It was easy and quick. I love the way it works with my other Eufy products. Would definitely purchase again. My only disappointment was that the instructions didn’t tell you that you have to press an “Enter” button after you enter the code. Once I realized that I needed to do that it was smooth sailing.
