eufy Security Smart Lock C33, Keypad Door Lock with Handle, Built-in Wi-Fi

The build quality and handle design stand out immediately. The lever has a solid heft to it--smooth and comfortable to grasp--and having lever hardware instead of a knob makes a difference when carrying groceries or juggling bags. It feels like a small upgrade that pays off every day. The most important feature for me is the ability to schedule it to lock at a certain time every night. Now I don’t lay in bed wondering if I remembered to lock the door; it just takes care of itself, and that peace of mind is huge. Fingerprint recognition isn’t flawless--it often works on the first try, but sometimes I have to try again--but it’s quick enough and reliable enough that I never think of it as a problem. Installation takes some patience, but the instructions are clear, and the process is very doable if you pay attention step by step. Once installed, the app setup is simple. I think of it as “set it and forget it”--I created the schedule, turned on notifications, and haven’t had to open the app again. Unlocking makes a quiet mechanical sound, and there’s a fairly loud beep by default that can be disabled (I turned it off right away). Durability has been excellent. My unit is fully exposed--no overhang, sitting in direct desert sun and rain for seven months--and it has never faltered. I’ve only had to replace the batteries once in that time, even with multiple entries and exits every day. The Wi-Fi connection has been rock solid as well; remote access has never failed me. I liked this lock so much that I purchased another one for my garage side door. It’s a product that combines comfort, reliability, and peace of mind in a way that makes it easy to recommend.

I really did not want a deadbolt lock and this lever smart lock from Eufy was exactly what I was looking for. I have a couple video doorbells from eufy and was really impressed with those and their build quality. I was equally impressed with the door hardware and the deadlatch was beefier than the deadlatch on the old doorlatch it was replacing. Directions were pretty good just so small to see, but I had watched the installation video and that was very helpful. Yes, it really only takes about 15 minutes to install and set up (excluding the software update it installed when I was finished) I also just flipped the deadbolt to the lower hole on the door to ensure the eufy latch had clearance (its tall and would not have fit under the deadbolt as was the original configuration on the door. I already had the deadbolt installed below the door latch on one of my exterior doors (I am tall and just like the latch on the higher hole) so that install was even quicker. The finger (thumbprint) reader works great and fast. Now we know our two basement doors and the garage door are locked and secure every evening now. It specially makes my wife happy as I was constantly leaving those doors unlocked because I was always in and out of them so often and it was a pain to remember a key or having one hanging near the back doors. Now it's fast easy access and I don't need to remember to lock them afterwards...the smart lock latches now remember for me. I do not know how long batteries will last but once they go, I am just going to replace all 8 of them with rechargeable lithium AAs. Right now, I would highly recommend these lever smart locks especially easy if you have no deadbolt above your latch but it's easy enough to just switch them around putting your deadbolt on the bottom and they look and feel really nice too.

Innovating lockers, responsive, and easy to install. It works well, connects well to wifi, easy to use on the app overall I would recommend it. The only thing it is missing is the ability to set up individual locker alarms on the eufy security hub like the eufy sensors otherwise I would give five starts.

Work fine, but for some reason battery don’t last long.

The eufy Security Smart Lock C33 has been a really solid purchase overall. Installation was straightforward, and the keypad and app setup were surprisingly easy to get working. I like having multiple ways to unlock the door, and the fingerprint reader is fast and accurate most of the time. The app controls are convenient too, especially for checking lock status and giving temporary access codes to guests or family members. The build quality feels sturdy and modern, and the lock looks great on the door without being bulky. Battery life has also been very good so far, which is important for a smart lock. The auto-lock feature gives extra peace of mind when leaving the house. A few small things could be improved, like the app occasionally taking a second to connect, but nothing major enough to take away from the experience. Overall, the eufy Security Smart Lock C33 is a dependable, easy-to-use smart lock that offers great features for the price, and I’d definitely recommend it to anyone looking to upgrade their home security.

I don’t know if this is a new product or my search terms were wrong, but I’ve been looking for over a year for something to keep my teenager from taking thing from my bedroom when I’m not home. Say what you will about my parenting, but for any situation where you want to control access to a room in your house, this lock gets it done. I love the fingerprint access for myself, and then either time or number of use limit codes for others, plus the ability to open it remotely on demand. On demand is a little tricky though, as I’ve found it works inconsistently. I have some misgivings about having yet another Anker smart device in my home (they also have this brand plus Soundcore and others) but this lock is the best option i’ve found. Hoping he price will continue to come down, but it if I need another smart interior lock I’ll buy this again.

This is a great lock and normally a very good price on Amazon. Installs easily and setup is quick and intuitive. The fingerprint programming is just like on your iPhone; the reader quickly recognizes your fingerprint at various angles. The integration with the Alexa skill took a little to figure out, but that works fine. The app makes it easy to add users, assign temporary codes, and unlock on demand. Wish there were a one-click button in the app or a keypad code to keep the door unlocked, but instead, you have to disable autolock in the app, which is less intuitive. You can adjust the volume or turn off the entry bell, but I would love to be able to change the tone as well. Also, it would be nice to have any brand of RFID card work and not have to purchase their special one. The unit feels very rugged and secure. Overall a good buy.

I own a lot of Eufy products and generally like them, but their smart locks relying on WiFi and cloud connectivity is a major drawback. Unlike Matter over Thread, which is self-healing, these locks don’t recover on their own. If my network goes down, the lock requires a full reconfiguration and I have to go through the pairing process again. In contrast, I have another smart lock connected via HomeKit that uses Matter over Thread. It remembers its settings and never needs repairing. I run a UniFi network with multiple VLAN options, including a dedicated 2.4GHz IoT network for all my smart devices. Even with this setup, the Eufy lock was a headache because it demands WiFi and cloud access just for setup. With Matter over Thread, everything runs locally through hubs like AppleTV or HomePods—it’s simpler and the network heals itself. Eufy makes solid hardware, but they’re stuck in the old model requiring cloud access over WiFi instead of embracing modern standards like Matter. Installation itself is straightforward—if you follow the official guide. You absolutely need to read the instructions or watch Eufy’s video. The lever has specific requirements, and you must use all the parts included in the box. Do not reuse parts from your old lock. It’s actually funny watching review videos where people skip steps and end up locked out or with a non-functional handle. Then they come here to blame the manufacturer, when the problem is clearly user error. That’s a fact. Stick to Eufy’s official tutorial—skip the YouTubers who often leave out important details or give oversimplified explanations. You’ve been warned. One feature I genuinely love about this lock is the internal clutch mechanism. It disengages the exterior handle, preventing anyone from applying weight to force the door open. Only authorized methods—fingerprint, password, NFC, or physical key—can engage the clutch and allow the handle to work. That’s excellent security. Another plus is flexibility. I was able to pair my Eufy cameras with the lock. When the clutch engages, the cameras automatically switch to recording that door. This deep integration is the main reason I stick with Eufy for security. They’re improving with sensors and other smart devices, but we really need alternatives to WiFi. A quick note on networks: Eufy devices prioritize 2.4GHz and don’t work well with 5GHz or tri-band setups. If your ISP router supports it, create a separate 2.4GHz IoT network and connect all smart devices there. Your ISP support can help, or you can buy your own router here on Amazon. To Eufy: Please implement Matter over Thread across all your products. It’s time.
