Understanding Your Eufy Smart Lock

Before diving into the how-to steps, it’s helpful to understand how your Eufy smart lock works. Eufy locks are battery-powered, Wi-Fi or Bluetooth-enabled devices that replace your traditional deadbolt. They connect to your smartphone via the Eufy Security app, allowing you to monitor and control your lock remotely.

Most Eufy locks feature a built-in keypad for PIN entry, a fingerprint scanner, and a physical key override in case of emergencies. They also support integration with voice assistants like Amazon Alexa and Google Assistant, so you can lock your door with a simple voice command.

One of the standout features of Eufy locks is their local data storage. Unlike some competitors, Eufy doesn’t store your data in the cloud, which means your access logs and fingerprints stay on the device itself. This enhances privacy but also means you need a stable connection between your phone and the lock for remote access.

Method 1: Locking Your Eufy Door Manually

The simplest way to lock your Eufy door is manually—no app or internet required. This method is perfect when you’re at home and want to secure your door quickly.

Using the Physical Thumb Turn

Every Eufy smart lock comes with a traditional thumb turn on the interior side of the door. This is the same mechanism you’d find on a standard deadbolt.

To lock your door using the thumb turn:

1. Stand inside your home facing the door.
2. Locate the thumb turn on the interior lock assembly.
3. Rotate the thumb turn clockwise until it stops.
4. You’ll hear a solid click, indicating the bolt has fully extended into the door frame.

This method is completely mechanical and doesn’t rely on batteries or Wi-Fi. It’s the most reliable way to lock your door, especially during power outages or technical glitches.

Using the Keypad (Exterior)

If you’re outside and want to lock the door without re-entering, you can use the keypad—if your model supports it.

To lock via the keypad:

1. Approach your door and wake up the keypad by touching any button.
2. Enter your 4- to 8-digit PIN code.
3. Press the lock icon (usually a padlock symbol) or the “#” key to confirm.
4. The lock will beep or flash to confirm it’s locked.

Some models allow you to lock the door by simply pressing the lock button after entering your code. Others may require a second step. Check your user manual for model-specific instructions.

Using the Physical Key (Emergency Override)

In rare cases—such as a dead battery or malfunction—you may need to use the physical key.

To lock with a key:

1. Insert the key into the keyhole on the exterior of the lock.
2. Turn the key clockwise to extend the deadbolt.
3. Remove the key and store it safely.

While this method is reliable, it bypasses smart features. Use it only when necessary and ensure your lock is functioning properly afterward.

Method 2: Locking Your Eufy Door Using the App

The Eufy Security app is the heart of your smart lock experience. It lets you lock and unlock your door from anywhere, view access logs, and manage user codes.

Downloading and Setting Up the Eufy Security App

If you haven’t already, download the Eufy Security app from the Apple App Store or Google Play Store. The app is free and works with all Eufy smart locks.

To set up the app:

1. Open the app and create an account using your email.
2. Tap “Add Device” and select your lock model.
3. Follow the on-screen instructions to pair your lock via Bluetooth.
4. Name your lock (e.g., “Front Door”) and assign it to a location.

Once paired, your lock will appear in the app dashboard.

Locking Your Door Remotely via the App

To lock your door using the app:

1. Open the Eufy Security app on your smartphone.
2. Tap on your lock from the home screen.
3. Tap the “Lock” button (usually a padlock icon).
4. Wait for confirmation—the app will show “Locked” and may send a notification.

You can do this from anywhere in the world as long as your phone and the lock are connected to the internet. This is especially useful if you forget to lock the door before leaving home.

Checking Lock Status in the App

The app also shows the current status of your lock—locked or unlocked. This is helpful for peace of mind, especially when you’re away.

To check status:

1. Open the app and go to your lock’s control screen.
2. Look at the status indicator at the top.
3. If it says “Unlocked,” you can tap “Lock” to secure it remotely.

You’ll also receive real-time notifications whenever someone locks or unlocks the door, so you’re always in the loop.

Method 3: Using Auto-Lock for Hands-Free Security

One of the smartest features of Eufy locks is Auto-Lock. This function automatically locks your door after a set period of time, so you never have to worry about forgetting.

How Auto-Lock Works

Auto-Lock monitors when your door is unlocked and waits for a specified delay—such as 30 seconds, 1 minute, or 5 minutes—before locking itself. It’s ideal for busy households or people who frequently forget to lock the door.

Enabling Auto-Lock in the App

To turn on Auto-Lock:

1. Open the Eufy Security app.
2. Tap on your lock and go to “Settings.”
3. Find “Auto-Lock” and toggle it on.
4. Choose your preferred delay time (e.g., 1 minute).
5. Save the settings.

Once enabled, your door will lock automatically every time it’s left unlocked. You can disable it anytime if you prefer manual control.

Tips for Using Auto-Lock Effectively

• Set a delay that matches your routine—shorter for quick exits, longer if you often step outside briefly.
• Test the feature by unlocking the door and waiting to see if it locks on time.
• Keep in mind that Auto-Lock won’t activate if the door is already locked or if the battery is low.

Auto-Lock is a game-changer for home security, especially for families with kids or elderly residents who might forget to lock the door.

Method 4: Locking Your Eufy Door with Voice Commands

If you use Amazon Alexa or Google Assistant, you can lock your Eufy door using just your voice. This is perfect for when your hands are full or you’re across the room.

Setting Up Voice Control

Before using voice commands, you need to link your Eufy account to your voice assistant.

For Alexa:

1. Open the Alexa app.
2. Go to “Skills & Games” and search for “Eufy Security.”
3. Enable the skill and log in with your Eufy account.
4. Discover devices—Alexa will find your lock.

For Google Assistant:

1. Open the Google Home app.
2. Tap “+” and select “Set up device.”
3. Choose “Works with Google” and find Eufy Security.
4. Log in and authorize access.
5. Assign your lock to a room.

Using Voice Commands to Lock

Once set up, you can say:

• “Alexa, lock the front door.”
• “Hey Google, lock the front door.”

The lock will respond with a verbal confirmation (if enabled) and a sound. You’ll also get a notification on your phone.

Voice Command Tips

• Use clear, specific names for your locks (e.g., “front door” vs. “lock”).
• Ensure your voice assistant can hear you—speak clearly and reduce background noise.
• Test the command when you’re home to confirm it works before relying on it remotely.

Voice control adds a layer of convenience, especially when you’re cooking, carrying groceries, or relaxing on the couch.

Method 5: Using Fingerprint or PIN to Lock

Some Eufy models, like the Smart Lock Touch, allow you to lock the door using your fingerprint or a PIN code—no app or voice needed.

Locking with Fingerprint

If your lock has a fingerprint scanner:

1. Place your registered finger on the scanner.
2. The lock will recognize you and unlock.
3. After entering, use the thumb turn or app to lock the door.

Note: Most Eufy locks don’t lock automatically via fingerprint—you still need to manually secure the door after entering.

Locking with a PIN Code

To lock using a PIN:

1. Enter your code on the keypad.
2. Press the lock button or “#” to confirm.
3. The lock will engage and confirm with a sound or light.

You can create multiple PINs for family members or guests. Manage them in the Eufy app under “User Codes.”

Troubleshooting Common Locking Issues

Even the best smart locks can run into problems. Here’s how to fix the most common issues when trying to lock your Eufy door.

Lock Won’t Respond to App Commands

If the app says “Lock” but nothing happens:

• Check your internet connection—both your phone and home Wi-Fi need to be working.
• Ensure the lock has sufficient battery (low power can limit remote functions).
• Restart the app and try again.
• If the problem persists, restart the lock by removing and reinserting the batteries.

Keypad Not Working

If the keypad is unresponsive:

• Clean the keypad with a dry cloth—dirt or moisture can interfere.
• Check battery levels; low power may disable the keypad.
• Ensure the lock isn’t in “Tamper Mode” (triggered by forced entry attempts).

Auto-Lock Not Activating

If Auto-Lock isn’t working:

• Confirm it’s enabled in the app settings.
• Check that the delay time is set correctly.
• Make sure the door is fully closed—Auto-Lock won’t work if the door is ajar.
• Update the app and lock firmware to the latest version.

Voice Commands Not Recognized

If Alexa or Google Assistant doesn’t respond:

• Verify the skill is enabled and linked to your account.
• Say the exact device name you assigned (e.g., “front door”).
• Check that your voice assistant is online and functioning with other devices.

Tips for Maintaining Your Eufy Lock

To keep your lock working smoothly:

• Replace batteries every 6–12 months, or when you get a low-battery alert.
• Clean the keypad and fingerprint scanner monthly.
• Update the app and firmware regularly for security and performance improvements.
• Test all access methods (app, keypad, voice) weekly to ensure they’re working.
• Keep the physical key in a safe, accessible place in case of emergencies.
