    Got a second one and it worked -- number pad and all fine. But when installed delicately the number pad failed again.

Eufy Smart Lock C33 2025 Version

  • Unlocking Methods+1 pts

    The fingerprint sensor works fast for me

  • App & Smart Home+1 pts

    Finally received the Eufy Smart Lock (2025 version) yesterday. The product itself looks and functions really nicely! Got no problem with the Eufy app and the smart lock itself is smooth. The fingerprint sensor works fast for me, and you can add more fingerprints per person (Access). I'm using 4 fingerprints just on my own and I think I can add more, and I added another access for my wife and daughter. Installation is easy, the manual has clear instructions. I only had a small problem with the door itself due to adjustment but it isn't really that hard for DIY. I'll be keeping the plastic cover on the front panel for a bit, since I don't intend to use the codes anyways. We really like the product, finally we don't have to bring those pesky keys with us. And to those asking what's the difference between the old model and this 2025 version, the truth is I have no idea since it's my first smart lock purchase. I'll be updating on the battery life once I get there.

    when I try to unlock the door through the app, it doesn't unlock and just shows an "operation failed" message

C33 Smart Lock Sometimes Repeatedly Fails To Read

  • Unlocking Methods-1 pts

    it won't unlock until I enter the numeric code. Then the next time I try my fingerprint it works on the first attempt. So it's only intermittent, but it's annoying when it happens

    I ended up fixing the issue by adding a WiFi extender and then connecting to that instead.

    If the batteries inside run out and you need to unlock the lock and don't have a key handy , you can connect a small external battery via USB-C and recharge it.

    The very tiny wires in the harness that goes through the door aren't properly protected and are way too easy to break, and when that happens it causes exactly these kinds of problems.

    I can't say for sure how much battery life is left since it's only showing old battery bar icons in the app.

    We have the wrong tribe protection. You can set how many times someone can try to unlock the lock before it locks down.

    if it's in red that means no one can access it even with the code. They have to have the physical key.

    It's not waterproof. I don't think it can handle rain because it's only rated IP53.
