eufy SecuritySmart Lock C34, Keyless Entry Door Lock with Apple Home Ecosystem, Built-in Wi-Fi Deadbolt for Front Door or Back, Supports Matter, Alexa, Google Home, SmartThings

So far good. I would say the lever can be less flimsy but it works always. The battery notification is helpful and the auto lock function works well too. Installation is fairly easy, just follow the instructions. However i have to say it is difficult ish to get the seal to properly seal the lock against the door for weatherproofing it. For the price, this is an excellent smart home lock that you can open/close from anywhere. No additional subscription needed. I actually used this to replace my schlage. The schlage build quality is nicer but i don’t think it’s 8x nicer compared to this.

Eufy Smart Lock Review — A Huge Upgrade Over Schlage EncodeAfter struggling with two Schlage Encode locks, I decided to replace them with Eufy smart locks, and I couldn’t be happier with the switch.My Experience With Schlage EncodeUnfortunately, the Schlage Encode locks consistently gave me trouble. Despite repeated attempts, I was unable to update the firmware, and getting the locks to join my Wi-Fi network was frustratingly unreliable. A quick search online confirmed that I wasn’t alone — plenty of other users reported the same issues. These ongoing problems eroded my confidence in the Schlage devices.Why Eufy Stands OutIn contrast, the Eufy smart locks have worked perfectly from day one. Setup was simple, and they connected to Wi-Fi without any hassle. The locks have been reliable ever since, with no dropped connections or update headaches.I also appreciate the build quality:The Eufy lock operates quietly — no loud clunking noises like I experienced with the Schlage.The rear latch feels solid, with no excessive play or looseness.Seamless integration with Doorbells like the e340 for unlockingFinal ThoughtsIf you’re looking for a smart lock that simply works, I highly recommend giving Eufy a try. After my disappointing experience with Schlage, Eufy’s reliability and thoughtful design have been a refreshing change.

Easy to install and to get working with app. One of two kits was missing an insignificant part (rubber aesthetic plug) that customer support sent out to me quickly and free of charge. One of those upgrades that made me ask myself, "Why didn't I do this sooner?!".

Installation was easy, mounting screws and plate feel secure. Can’t comment on battery life yet. The Eufy app is pretty good and straightforward. Contrary to Amazon’s Rufus AI, this lock does NOT support Apple Home Key. But it’s integration with HomeKit works well, and you can set up an automation with Apple Shortcuts and a third party NFC tag to achieve a similar experience to Home Key.

I regret purchasing the Eufy Smart Door Lock C34 due to its **serious battery drainage issue**. Initially, I thought I had received a defective unit, so I requested an exchange. However, the replacement suffered from the exact same problem, indicating this is a **systemic flaw in the product's design**.After installing **new batteries on a Friday**, I left my home for a week—meaning the lock had **zero activity**. Despite this, the batteries were completely **dead** before I returned. This was not due to weak signal strength or distance; the only reasonable conclusion is **poor design and inefficient power management**.I’ve finally **given up** on trying to make this lock work, and I wish I could get my money back. A smart lock that **cannot hold a charge for more than a week—even when unused—is completely unreliable**. I wouldn’t recommend this product to anyone until Eufy addresses these units!

I have been using smart locks for years, and this is my third. The Eufy replaced an August lock, so that will be the direct comparison.The August just replaced the inside portion, so reused the deadbolt mechanism. This Eufy replaces the entire unit, which has both advantages and disadvantages. If you're a renter, or want/need to maintain the existing key, leaving the existing deadbolt is preferred. However, replacing the entire mechanism, like the Eufy does, allows for more features, like the included keypad and fingerprint reader. For the August, the keypad was an add on.The Eufy also included wifi built-in, where with the August it was a separate component that was plugged in near the lock. While that requires more batteries for the Eufy, I prefer the all-in-one solution.The other advantage of the Eufy replacing the entire mechanism is how much more positive and direct the lock feels when locking/unlocking it manually. The August would sometimes get out of sync, and when turning the lock knob by hand, it would engage the motor and you would be turning that, too. The motorized locking is also more precise, and quieter, on the Eufy.The last advantage is really only for those already using Eufy. Having it integrated with the camera app is great. If you have a camera at the entry, you can locl/unlock the door from the same screen as viewing the camera.The fingerprint scanner works great, and is faster and easier than using a code. The one complaint I have is in the app. If you add codes for people like pet sitters, cleaning people, etc., you are limited in terms of how you allow them to use the lock. It's either always or scheduled. And you can't change that without removing the code and adding it back. You also can turn a code on and off. You have to remove it and add it. That's annoying and an inexcusable oversight. Hopefully that will be addressed at some point, but I don't have high hopes.

I purchase this lock after visiting my son in Dallas. I got lock out but able to open the door through remote control from my in law app. It took my husband about 1/2 hours from install to set up. The lock works great with good build quality. My husband has to repaint all handle to match the look, it takes him more time to repaint everything than to install the lock. The rechargeable battery is a plus.
