Why Locking Your Eufy Devices Matters

Before diving into the steps, it’s important to understand why locking your Eufy devices is so crucial. Eufy devices are designed to give you control over who enters your home and when. But if those devices aren’t properly secured, they could become a weak link in your security chain.

For example, a smart lock that doesn’t lock automatically could leave your front door vulnerable. Or, if your Eufy Security app isn’t protected with strong authentication, someone could access your camera feeds or unlock your doors remotely. Locking your Eufy devices—both physically and through software settings—ensures that only authorized users can interact with them.

Additionally, many Eufy devices offer features like geofencing, auto-lock timers, and remote access. These tools are powerful, but they only work if your system is properly configured and secured. Locking your devices isn’t just about flipping a switch—it’s about creating a layered defense that keeps your home safe from intruders, hackers, and accidental mishaps.

Understanding Your Eufy Device Types

Eufy offers several types of smart home devices that can be locked or secured in different ways. Knowing which device you have will help you follow the right steps.

Eufy Smart Locks

These include models like the Eufy Smart Lock Touch, Smart Lock S330, and Smart Lock C210. These locks replace or enhance your existing deadbolt and allow you to lock and unlock your door using a keypad, fingerprint, app, or voice commands.

Eufy Video Doorbells

Devices like the Eufy Video Doorbell Dual or Doorbell E340 may not physically lock your door, but they can integrate with smart locks and offer features like two-way audio, motion detection, and remote access. Securing the app and enabling privacy modes is key.

Eufy Security Cameras

Indoor and outdoor cameras (e.g., EufyCam 2C, SoloCam S40) don’t lock doors, but they do record footage and send alerts. Locking down access to your camera feeds prevents unauthorized viewing.

Eufy Security App

This is the central control hub for all Eufy devices. Locking your account with strong passwords and two-factor authentication is one of the most important steps in securing your entire system.

How to Lock Eufy Smart Locks

If you have a Eufy Smart Lock, locking it is straightforward—but there are several methods and settings to explore.

Manual Locking via Keypad or Fingerprint

Most Eufy Smart Locks come with a built-in keypad or fingerprint scanner. To lock the door manually:

Stand in front of your door with the lock.
Press the lock button on the keypad (usually a padlock icon).
Alternatively, use your registered fingerprint to trigger the lock.
Listen for the locking sound or check the LED indicator (usually green or blue when locked).

Tip: Always test the lock after use to ensure it’s fully engaged. A partially locked door can be a security risk.

Locking via the Eufy Security App

The app gives you remote control over your lock, even when you’re not home.

Open the Eufy Security app on your smartphone.
Tap on your Smart Lock device from the home screen.
Tap the Lock button (padlock icon).
Wait for confirmation that the lock has engaged.

Example: If you’re at work and realize you forgot to lock the door, open the app, tap your lock, and secure it in seconds.

Setting Up Auto-Lock

Auto-lock ensures your door locks automatically after a set time, reducing the chance of human error.

Open the Eufy Security app.
Go to your Smart Lock settings.
Tap Auto-Lock or Auto Lock Timer.
Choose a time delay (e.g., 30 seconds, 1 minute, 5 minutes).
Save the setting.

Tip: A 30-second delay is ideal for most homes—it gives you time to enter without fumbling, but locks quickly enough to deter intruders.

Using Geofencing to Lock Automatically

Geofencing uses your phone’s location to trigger actions when you leave or return home.

In the Eufy app, go to Settings > Geofencing.
Enable geofencing for your Smart Lock.
Set a radius (e.g., 100 meters).
Choose to Lock when away and Unlock when home.

Note: Make sure location services are enabled on your phone for this to work.

How to Lock Eufy Video Doorbells and Cameras

While doorbells and cameras don’t physically lock your door, they do need to be secured to protect your privacy and data.

Enable Privacy Mode

Privacy mode disables recording and live view when you’re home.

Open the Eufy Security app.
Select your doorbell or camera.
Tap the Privacy Mode toggle to turn it on.
Set a schedule or enable it manually.

Tip: Use privacy mode during family gatherings or when you don’t want to be recorded.

Restrict Access to Camera Feeds

Only authorized users should be able to view your camera footage.

Go to Settings > User Management.
Add trusted users with limited permissions (e.g., view-only).
Remove any unknown or old accounts.

Example: Give your spouse full access, but limit a house sitter to viewing only—no deleting recordings or changing settings.

Disable Two-Way Audio When Not Needed

Two-way audio lets you speak through the doorbell, but it can be a privacy risk if left on.

In the app, go to your doorbell settings.
Toggle off Two-Way Audio when not in use.
Re-enable it when expecting visitors.

How to Lock Your Eufy Security App

Your app is the gateway to all your devices. Securing it is just as important as locking your front door.

Set a Strong Password

Use a unique, complex password for your Eufy account.

Include uppercase, lowercase, numbers, and symbols.
Avoid common words or personal info (e.g., “password123” or your birthday).
Use a password manager to store it securely.

Enable Two-Factor Authentication (2FA)

2FA adds an extra layer of security by requiring a code from your phone when logging in.

Open the Eufy Security app.
Go to Settings > Account Security.
Tap Two-Factor Authentication.
Follow the prompts to link your phone number or authenticator app.
Save backup codes in a secure place.

Tip: Use an authenticator app like Google Authenticator instead of SMS for better security.

Log Out of Unused Devices

If you’ve logged in on a public or shared device, always log out.

Go to Settings > Device Management.
See a list of devices where you’re logged in.
Tap Log Out on any unfamiliar or unused devices.

Best Practices for Locking Eufy Devices

To get the most out of your Eufy system, follow these best practices.

Update Firmware Regularly

Eufy releases updates to fix bugs and improve security.

Open the Eufy app.
Go to Settings > Device Settings.
Tap Firmware Update.
Install any available updates.

Tip: Enable auto-updates if available to stay protected without manual checks.

Use Unique Access Codes

If your lock has a keypad, assign unique codes to family members or guests.

Go to User Management in the app.
Add a new user and assign a 4-8 digit code.
Delete codes when guests leave.

Example: Give your teenager a code that only works after 3 PM on school days.

Test Your System Weekly

Make it a habit to test your locks, cameras, and app access.

Try locking and unlocking remotely.
Check camera feeds for clarity and motion alerts.
Verify that auto-lock and geofencing work as expected.

Troubleshooting Common Locking Issues

Even the best systems can have hiccups. Here’s how to fix common problems.

Lock Won’t Engage

Check battery level: Low batteries can prevent locking. Replace if below 20%.
Ensure door is closed: Most locks won’t engage if the door is ajar.
Restart the lock: Turn off power, wait 10 seconds, then turn it back on.

App Can’t Connect to Lock

Check Wi-Fi signal: Move closer to the router or use a Wi-Fi extender.
Restart the app: Close and reopen the Eufy Security app.
Re-sync the device: Remove and re-add the lock in the app.

Geofencing Not Working

Enable location services: Go to phone settings and allow location access for the Eufy app.
Check battery optimization: Some phones restrict background app activity. Disable battery optimization for Eufy.
Test with a smaller radius: Start with 50 meters to ensure it triggers correctly.

Two-Factor Authentication Not Sending Codes

Check network connection: Ensure your phone has signal or Wi-Fi.
Use an authenticator app: If SMS fails, switch to Google Authenticator or Authy.
Contact support: If issues persist, reach out to Eufy customer service.

Create a Guest Mode

Temporarily disable certain features when guests are over.

Use Voice Commands Wisely

If you use Alexa or Google Assistant, be cautious with voice unlocking.

Disable voice unlock in public spaces.
Use voice only for checking status (“Is the door locked?”).
Require a PIN for voice commands if supported.

Monitor Activity Logs

Review who accessed your locks and when.

Go to Activity in the app.
Check timestamps and user names.
Investigate any suspicious entries.
