Let’s get started!

What You’ll Need Before Starting

Before diving into the setup, make sure you have the following items ready:

• Your Eufy smart lock: Confirm it’s a WiFi-enabled model (e.g., Smart Lock Touch, Smart Lock U10, or Smart Lock Pro).
• A smartphone or tablet: iOS or Android device with the latest operating system.
• The Eufy Security app: Download it from the App Store or Google Play.
• WiFi network details: Your network name (SSID) and password.
• Fully charged lock batteries: Low power can disrupt the setup process.
• Access to your home’s WiFi router: In case you need to restart it or check settings.

Having these ready will save time and prevent frustration during setup.

Step 1: Download and Set Up the Eufy Security App

The Eufy Security app is your control center for all Eufy smart devices. It’s essential for connecting your door lock to WiFi and managing its features.

Download the App

Open the App Store (iOS) or Google Play Store (Android) on your smartphone. Search for “Eufy Security” and download the official app by Eufy Security. Make sure it’s the correct one—look for the blue and white logo with a shield icon.

Create an Account

Open the app and tap “Sign Up” to create a new account. You’ll need to provide a valid email address and create a strong password. Eufy may send a verification email—check your inbox and click the link to confirm your account.

Enable Permissions

The app will request access to your location, Bluetooth, and notifications. Allow these permissions so the app can detect your lock, pair via Bluetooth, and send alerts when someone locks or unlocks the door.

Log In

Once your account is verified, log in to the app. You’ll land on the home screen, which shows all connected Eufy devices. Since your lock isn’t set up yet, it will be empty—but that’s about to change!

Step 2: Prepare Your Eufy Door Lock

Before connecting to WiFi, you need to prepare your lock for pairing. This involves installing it (if not already done) and ensuring it’s in setup mode.

Install the Lock (If Not Already Done)

If you haven’t installed your Eufy lock yet, follow the manufacturer’s installation guide. Most Eufy models are designed for standard doors and come with detailed instructions and mounting hardware. Key steps include:

• Removing your existing deadbolt.
• Installing the new lock mechanism from the inside and outside.
• Connecting the interior and exterior parts with the provided cable.
• Securing the mounting plate and faceplate.

Make sure the lock operates smoothly by testing the manual key and thumb turn before proceeding.

Insert and Charge the Batteries

Eufy locks are powered by rechargeable lithium-ion batteries. Insert the battery pack into the designated compartment on the interior side of the lock. If the battery is low or new, charge it fully using the included USB-C cable. A full charge takes about 3–4 hours and provides up to 12 months of use, depending on activity.

Enter Pairing Mode

To connect your lock to the app, it must be in pairing mode. Here’s how:

1. Press and hold the “Pair” button (usually located on the interior side of the lock, near the battery compartment) for 5 seconds.
2. The lock will emit a beep, and the LED indicator will flash blue—this means it’s ready to pair.

Keep the lock in this mode while you proceed to the next step.

Step 3: Pair the Lock with the Eufy Security App

Now that your lock is in pairing mode, it’s time to connect it to the app via Bluetooth. This initial connection is necessary before enabling WiFi.

Open the App and Add a Device

In the Eufy Security app, tap the “+” icon (usually in the top-right corner) to add a new device. Select “Smart Lock” from the list of device types.

Search for Your Lock

The app will scan for nearby Eufy devices using Bluetooth. Make sure your phone is within 10 feet of the lock. When your lock appears on the screen (usually labeled by model name), tap it to begin pairing.

Confirm Pairing

The app will send a pairing request. Confirm it on your phone. The lock will beep again, and the LED will turn solid blue, indicating a successful Bluetooth connection.

Name Your Lock

Give your lock a name, such as “Front Door” or “Back Entrance,” so you can easily identify it in the app. You can also assign it to a room or location for better organization.

Step 4: Connect Eufy Door Lock to WiFi

This is the main event—connecting your Eufy lock to your home WiFi network. Once connected, you’ll be able to control the lock remotely, receive notifications, and integrate it with other smart home devices.

Ensure You’re on a 2.4 GHz Network

Eufy smart locks only support 2.4 GHz WiFi networks. If your router broadcasts both 2.4 GHz and 5 GHz signals under the same name (SSID), you may need to temporarily disable the 5 GHz band or rename the networks to distinguish them.

To check your network:

• Go to your phone’s WiFi settings.
• Look for your network name—2.4 GHz networks often include “2.4” or “_2G” in the name.
• If unsure, log into your router’s admin panel (usually via a web browser) and check the wireless settings.

Enter WiFi Credentials in the App

Back in the Eufy Security app:

1. After pairing, the app will prompt you to connect the lock to WiFi.
2. Tap “Connect to WiFi” and select your 2.4 GHz network from the list.
3. Enter your WiFi password carefully—case-sensitive and including any special characters.
4. Tap “Connect.”

Wait for the Connection

The app will send the WiFi details to the lock via Bluetooth. The lock will then attempt to connect to your network. This process can take 30–60 seconds.

During this time, the lock’s LED will flash amber. Once connected, it will turn solid green, and the app will display a success message.

Test the Connection

To confirm the WiFi connection is working:

• Close the app and walk away from your home (or turn off your phone’s WiFi and use mobile data).
• Open the app again and try to lock or unlock the door remotely.
• If the action completes successfully, your lock is connected to WiFi!

Step 5: Set Up Smart Features and Notifications

Now that your Eufy lock is online, it’s time to customize its features for maximum convenience and security.

Enable Push Notifications

Go to the app’s settings for your lock and turn on notifications. You’ll receive alerts whenever someone locks or unlocks the door, uses a code, or attempts to tamper with the lock.

Create Access Codes

Set up unique PIN codes for family members, guests, or service providers. You can assign temporary codes with expiration dates—perfect for Airbnb hosts or dog walkers.

Enable Auto-Lock

Set the lock to automatically relock after a certain time (e.g., 30 seconds, 1 minute). This ensures your door is never accidentally left unlocked.

Integrate with Smart Home Systems

If you use Alexa, Google Assistant, or Apple HomeKit, link your Eufy account to enable voice commands. For example, say “Alexa, lock the front door” to secure your home hands-free.

Enable Two-Factor Authentication (2FA)

For added security, enable 2FA in the Eufy app. This requires a verification code (sent via SMS or email) when logging in from a new device, protecting your smart lock from unauthorized access.

Troubleshooting Common WiFi Connection Issues

Even with careful setup, you might encounter problems when connecting your Eufy lock to WiFi. Here are solutions to the most common issues.

Lock Won’t Connect to WiFi

• Check WiFi signal strength: Move closer to your router or consider a WiFi extender if the lock is far from the router.
• Restart the lock: Power it off by removing the battery for 10 seconds, then reinsert and try again.
• Re-enter WiFi password: Typos are common—double-check for correct spelling, spaces, and special characters.
• Reset network settings: In the app, go to lock settings and select “Forget WiFi,” then reconnect.

App Shows “Offline” or “Connection Failed”

• Ensure Bluetooth is on: The app uses Bluetooth to send WiFi credentials—keep it enabled during setup.
• Update the app: Outdated versions may have bugs. Check for updates in your app store.
• Restart your phone: A simple reboot can resolve connectivity glitches.
• Check router settings: Some routers block IoT devices. Ensure your router allows connections from new devices and disable “AP isolation” if enabled.

Lock Disconnects Frequently

• Improve WiFi coverage: Use a mesh network or extender to boost signal in your entryway.
• Avoid interference: Keep the lock away from microwaves, cordless phones, or thick walls that block signals.
• Update firmware: Eufy releases updates to improve stability. Check for updates in the app under device settings.

Battery Drains Quickly After WiFi Setup

WiFi connectivity uses more power than Bluetooth-only mode. If your battery drains faster than expected:

• Ensure the lock has a strong WiFi signal—weak signals cause repeated connection attempts.
• Reduce notification frequency in the app settings.
• Consider using a high-quality, fully charged battery pack.

Tips for Maintaining a Stable WiFi Connection

Once your Eufy lock is connected, follow these best practices to keep it running smoothly:

• Keep the app updated: Regular updates improve performance and security.
• Monitor battery levels: The app will alert you when the battery is low—replace it promptly.
• Test remote access monthly: Ensure you can still lock/unlock from outside your home.
• Secure your WiFi network: Use a strong password and WPA3 encryption to prevent hacking.
• Avoid changing WiFi settings frequently: If you rename or reset your network, you’ll need to reconnect the lock.
