You get home with groceries and find that your smart lock shows as offline in the app. If the lock still has power, a previously set up keypad code or other local entry method may continue to work, even though remote controls and alerts pause. This guide explains how to tell an internet outage from a lock problem, check your available ways in, and prepare a backup before you need one.
First, Check Whether the Internet or the Lock Has Failed
An offline message does not tell you why a door will not open: Your internet service may be down, the lock may have lost its Wi-Fi connection, its battery may be low, or the deadbolt may be binding against the strike plate. Those problems call for different fixes. Start by checking whether another device can reach the internet and whether the lock responds to its keypad, fingerprint reader, or other local control.

If the lock responds at the door but not in the app, focus on the network path. If there is no light or sound from the lock, check its power supply and the emergency power procedure in the manual. If the motor runs but the bolt will not move, do not keep forcing it. Check whether the door is fully closed and whether the bolt can move freely with the door open.
Quick shortcut: If other smart-home devices go offline at the same time, the problem is more likely your network or router than the lock itself.

Use the Local Entry Method Your Model Supports
Many smart locks can check credentials at the door without a live internet connection, provided the lock has power and those credentials were set up before the outage. Which methods remain available depends on the model. The useful question is not simply whether a lock has an app, but whether your household has tested a way to enter without it.
Entry method
What to verify before relying on it
Keypad code
Confirm that an existing code unlocks the door with Wi-Fi disconnected.
Fingerprint or face recognition
Test an already enrolled user; availability varies by model and power state.
Bluetooth app control
Check whether the app connects directly when your phone is near the lock.
Physical key
Use it only if your particular lock has a key cylinder and you have the correct key.
Test before you rely on it: while someone can still open the door another way, verify each method with the Wi-Fi disconnected — and repeat the test with every household member who needs access. New codes, guest invitations, and app-based changes may need a working connection, so set up household access ahead of time rather than during an outage.
Expect Remote Features to Pause Until Connectivity Returns
Remote locking and unlocking, away-from-home status checks, push alerts, and live video typically depend on the lock's connection to your network or a connected hub. If that path is down, treat the app's last displayed status as potentially stale. Do not assume a remote unlock request went through just because you tapped the button.
Bluetooth is different from remote Internet access. On a model that supports direct Bluetooth control, the phone may still communicate with the lock when you are standing nearby, but that does not restore control from across town. Likewise, a local keypad working at the door does not mean notifications or event history are updating in real time. Check the manual to see how your model handles any activity recorded while offline.
Restore the Connection without Resetting Access
Once everyone can enter safely, restore the connection in order. Check whether your internet service is working, then whether the router and any required bridge or hub have power. Look for a weak Wi-Fi signal, or whether the network name or password has changed. After service returns, give the lock and app time to reconnect, and confirm the status from the door itself.
A factory reset should be a last step, not the first response to an offline message. It may remove settings or credentials that are still useful locally. Follow the model's support instructions before changing network settings, firmware, or permissions, and contact the manufacturer if the lock remains offline after the rest of the network is restored.
Prepare Before the Next Outage
Make a Backup Entry Plan for Everyone Who Needs the Door
Choose at least one entry method that does not depend on a phone reaching the Internet, then test it with each authorized household member. Keep the lock's battery maintained and know where its emergency power point is, if it has one. If the model includes a physical key, store a spare in a secure location accessible to a trusted person, rather than leaving it near the door.
Think through less routine arrivals too: a child returning from school, a caregiver, or a guest arriving while you are away. A preassigned code may be more dependable than trying to create access after the connection fails. When comparing smart locks, look at the local entry methods, backup power design, and how easily you can test both. No single feature replaces a practical household access plan.
Choose a Lock with Offline Access You Can Verify
Before choosing a smart lock, picture each person arriving home when the internet is down. Can they unlock the door without relying on a remote command? The eufy Smart Lock E40 is worth considering if your household wants face recognition and PIN entry at the door. It also has a rechargeable main battery and a built-in backup battery that can provide power for unlocking when the main battery runs low. Those features address two different concerns: losing your internet connection and losing battery power. Before relying on either method, check the current E40 manual for its offline behavior. Enroll the people who need access, then test their chosen entry methods with the internet disconnected while someone can still let them in another way. That gives you a household backup plan you have actually verified, rather than one based on a feature list.
Conclusion
An internet outage may disrupt remote features while some local unlocking methods continue to work, depending on the lock model and configuration. Before an outage, make sure everyone who needs access is registered, test offline unlocking methods, keep the lock’s batteries in good condition, and arrange a backup for anyone who cannot use the app.
During an outage, check that the lock itself responds and use an unlocking method you have already tested. Treat the status shown in the app as potentially outdated until your home internet connection is restored. Once service returns, confirm that registered users can still access the lock and test the entry methods they rely on.
