Faqs

How do I set up my eufy Smart Lock for the first time?

Start by installing the lock hardware, inserting the batteries, and downloading the eufy Security app. Open the app, create an account, and add the lock by scanning the QR code or following the device-add prompts. After pairing, complete calibration so the lock recognizes the door’s open and closed positions. Finish by naming the lock, creating a passcode, and testing the lock several times with the door open before relying on it daily.

Why won’t my eufy Smart Lock connect to Wi-Fi during setup?

If your eufy Smart Lock will not connect to Wi-Fi, first confirm that you are using the correct home network and password. Keep the lock close to the router during setup and make sure Bluetooth pairing is complete before Wi-Fi is added. Restarting the app, replacing weak batteries, and checking for router restrictions such as band steering or hidden SSIDs can also help. If needed, reset the lock and repeat the setup steps slowly.

What should I do if my eufy Smart Lock is not calibrating correctly?

Calibration problems usually happen when the lock is installed slightly out of alignment or the door is not moving smoothly. Check that the deadbolt turns freely by hand before using the app. Make sure the interior unit is firmly attached, the strike plate is aligned, and the door is fully closed during calibration. If the app still fails, remove the batteries, restart setup, and run calibration again with the door open first, then closed.

Can I use eufy Smart Lock with my existing door hardware?

eufy Smart Lock models are designed for standard entry doors, but compatibility depends on your door thickness, bore hole size, and deadbolt style. Before buying, verify that your door matches the installation guide and that the existing deadbolt area is clean and level. Some doors may need minor adjustments to the strike plate or mounting screws. If the lock feels tight or uneven, stop and recheck alignment before finishing setup.

How do I add fingerprints and PIN codes to my eufy Smart Lock?

After installation, open the eufy Security app and go to the lock’s access settings. You can usually create a PIN code, then enroll fingerprints by following the on-screen instructions and touching the sensor from different angles. For best recognition, register the same finger multiple times if the app allows it, and keep the sensor clean. Test each fingerprint and code immediately to confirm that entry works reliably from outside the door.

Why does my eufy Smart Lock beep but not unlock the door?

A beep without unlocking often points to a deadbolt alignment issue, low batteries, or incomplete calibration. First, check whether the bolt moves smoothly when the door is open. Replace weak batteries and confirm the lock’s interior assembly is secure. If the keypad or fingerprint reader responds but the bolt stays stuck, the strike plate may need repositioning. Recalibrate the lock in the app after fixing any mechanical resistance.

How can I improve the battery life of my eufy Smart Lock?

To extend eufy Smart Lock battery life, use high-quality batteries and replace the full set at the same time. Reduce unnecessary app checks, avoid repeated failed unlock attempts, and keep firmware updated because software improvements can improve efficiency. Make sure the door closes smoothly so the motor does not work harder than needed. Extreme cold can also reduce battery performance, so watch battery alerts more closely during winter months.

What is the best way to clean and maintain a eufy Smart Lock?

Use a soft, dry cloth to clean the keypad, fingerprint sensor, and housing regularly. Avoid harsh cleaners, water spray, or abrasive materials that can damage the finish or sensor surface. Check screws, batteries, and the strike plate every few months to make sure the lock remains aligned and secure. If the fingerprint reader becomes less responsive, wipe it gently and re-register fingerprints if needed for more consistent access.
