Eufy Smart Lock Keeps Going Offline: Try These Troubleshooting Tips

1. Replace or Charge the Batteries

As mentioned above, there may be several reasons your Eufy lock won’t stay connected. But before trying other fixes, check and replace/recharge the batteries, if needed.

Low batteries can reduce your Eufy lock performance and this could be the reason for the offline issues.

You can test your Eufy lock battery power by trying to unlock it with a fingerprint or passcode. If it’s slow to respond or won’t work at all, it’s a sign that the battery power is weak.

Replace the batteries or charge the existing ones and monitor the app to see if it goes offline again. If it still goes offline, continue to the next step.

2. Reboot Your Wi-Fi Router

Network interferences may sometimes lead to connectivity issues with smart devices. And one way to troubleshoot this issue is to reboot the Wi-Fi router.

You can reboot your router by unplugging it from the power source (outlet) and plugging it back in. Wait for a few seconds after unplugging it before plugging it back in.

If this doesn’t help, continue to the next step.

3. Check Your Wi-Fi Band

Eufy smart lock only supports the 2.4GHz Wi-Fi band. If your router has a dual-band and automatically switches bands, there’s a chance that your lock will go offline if the router switches to a 5GHz band.

Go over to your router’s settings and set the Wi-Fi band to operate on 2.4GHz.

If your lock still shows offline in the Eufy Security app, continue to the next step.

4. Check Your Wi-Fi Signal Strength

Another likely cause of offline issues with the Eufy lock is low Wi-Fi signal strength. What this means is, the lock requires strong network signals from your router to stay connected. And if your router isn’t supplying the required network strength, the lock may keep disconnecting and showing offline in the app.

One common cause of poor Wi-Fi signal strength is the distance between your router and the device. Check whether your router is located too far from the lock and try bringing it closer.

Also, thick concrete walls can block Wi-Fi network signals, so ensure there’s no wall between your router and the lock, or better still, get a Wi-Fi extender to boost your Wi-Fi coverage.

5. Update the App

Running an outdated version of the Eufy Security app may cause some niggling issues (such as offline/connectivity issues).

Depending on your device’s operating system, go over to Google Play Store or Apple App Store and update the app—if there are new updates.

6. Reboot Your Lock

Sometimes, issues like this could come from the lock, and you may fix this by rebooting the lock.

You can reboot your Eufy smart lock by pressing and holding the reboot button (located at the bottom of the lock—near the USB port) for a few seconds.

If you still experience an offline issue, the next thing you want to do is contact Eufy Customer Support for help.

Wrapping Up

So there it is! You should be able to resolve offline issues with your Eufy smart lock by applying the troubleshooting tips in this post.

To recap, if your Eufy smart lock keeps showing offline in the app, check and replace the batteries or charge the battery via the USB port. If that doesn’t help, check your Wi-Fi network signal strength and ensure it’s operating on the 2.4GHz band.

Also, update the app, reboot your router and the lock. This should fix the offline issue. But if everything fails, get in touch with Eufy Support for help.
