Eufy, a brand under Anker, specializes in smart home security products, including video doorbells, indoor cameras, and smart locks. Their smart locks are designed to replace traditional deadbolts and offer keyless entry through fingerprint scanning, PIN codes, smartphone control, and physical keys (as a backup).

Popular models include:
– Eufy Smart Lock (basic model with app control)
– Eufy Smart Lock Touch (fingerprint + keypad)
– Eufy Smart Lock Bolt (ultra-slim design, no hub required)
– Eufy Smart Lock C21 (with built-in Wi-Fi)

All these locks allow you to lock and unlock your door remotely, but the exact steps may vary slightly. This guide covers the most common methods across models.

How to Lock Eufy Security Lock Manually

Sometimes, the simplest method is the best. If your phone is dead, the app is glitching, or you just prefer physical control, you can always lock your Eufy smart lock manually.

Using the Interior Thumb Turn

Most Eufy smart locks have a thumb turn on the interior side of the door—just like a traditional deadbolt.

  1. Stand inside your home, facing the door.
  2. Locate the thumb turn on the interior lock assembly.
  3. Turn it clockwise until you hear a solid click.
  4. Test the door by trying to open it from the outside—it should be locked.

Tip: Always make sure the thumb turn is fully engaged. A partial turn might not fully lock the bolt, leaving your door vulnerable.

Using the Keypad (If Equipped)

If your Eufy lock has a built-in keypad (like the Smart Lock Touch), you can lock it from the outside without a phone or key.

  1. Stand outside your door.
  2. Enter your personal PIN code on the keypad.
  3. Press the lock button (usually a padlock icon or the “#” key).
  4. The lock will engage, and you may hear a beep or see a light flash.

Example: If your PIN is 1234, press 1-2-3-4, then press the lock icon. The bolt should extend into the door frame.

Note: Some models require you to press “#” after entering the code to confirm the lock command.

Using a Physical Key (Backup Method)

Every Eufy smart lock comes with a physical key as a backup. This is useful during power outages or if the lock malfunctions.

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

Important: Keep your keys in a secure location—don’t leave them under the doormat or in a fake rock. Consider giving a spare to a trusted neighbor or family member.

How to Lock Eufy Security Lock Using the App

The EufySecurity app is the heart of your smart lock experience. It lets you control your lock remotely, monitor access, and customize settings.

Download and Set Up the EufySecurity App

If you haven’t already installed the app, follow these steps:

  1. Download the “EufySecurity” app from the Apple App Store or Google Play Store.
  2. Create an account or log in if you already have one.
  3. Tap the “+” icon to add a new device.
  4. Select “Smart Lock” and follow the on-screen instructions to pair your lock.
  5. Make sure your phone is connected to the same Wi-Fi network as your lock (if applicable).

Tip: For locks with built-in Wi-Fi (like the Smart Lock Bolt), pairing is faster. For older models, you may need a Eufy HomeBase hub.

Locking Your Door via the App

Once your lock is connected, locking it remotely is easy.

  1. Open the EufySecurity app.
  2. Tap on your smart lock from the device list.
  3. On the lock screen, tap the “Lock” button (usually a padlock icon).
  4. Wait a few seconds for the lock to respond—you’ll see a confirmation message.
  5. Optional: Check the status indicator (green = locked, red = unlocked).

Example: You’re at work and realize you forgot to lock the door. Open the app, tap your lock, and press “Lock.” Done.

Using Geofencing to Auto-Lock When You Leave

Geofencing uses your phone’s location to trigger actions. You can set your Eufy lock to automatically lock when you leave a certain area (like your home).

  1. Open the EufySecurity app.
  2. Go to your lock’s settings.
  3. Tap “Geofencing” or “Auto Lock.”
  4. Enable the feature and set your home location.
  5. Choose the action: “Lock when leaving.”
  6. Set a delay (e.g., 30 seconds after you leave).

Note: Geofencing requires location permissions on your phone. Make sure they’re enabled for the EufySecurity app.

How to Enable Auto-Lock on Eufy Smart Lock

Auto-lock is one of the most useful features of a smart lock. It ensures your door is never accidentally left unlocked—even if you forget.

Setting Up Auto-Lock in the App

  1. Open the EufySecurity app.
  2. Select your smart lock.
  3. Tap the gear icon to access settings.
  4. Find “Auto Lock” or “Auto Lock Timer.”
  5. Toggle it on.
  6. Choose a time delay: 30 seconds, 1 minute, 2 minutes, etc.
  7. Save your settings.

Example: Set auto-lock to 30 seconds. After you unlock the door and walk in, the lock will automatically re-engage after half a minute.

Why Auto-Lock Is Important

– Prevents accidental unlocking
– Great for families with kids or forgetful adults
– Adds an extra layer of security
– Works even if you don’t have your phone

Tip: If you have pets or frequent deliveries, consider a longer delay (like 2 minutes) to avoid locking yourself out.

How to Lock Eufy Security Lock with Voice Commands

If you use Amazon Alexa or Google Assistant, you can lock your Eufy smart lock using voice commands.

Linking Eufy to Alexa or Google Assistant

  1. Open the Alexa or Google Home app.
  2. Tap “Devices” > “+” > “Add Device.”
  3. Search for “Eufy” and select your lock.
  4. Log in to your Eufy account when prompted.
  5. Follow the setup steps to link the accounts.

Using Voice Commands

Once linked, try these commands:

– “Alexa, lock the front door.”
– “Hey Google, lock the smart lock.”

The lock will respond with a confirmation sound or light, and you’ll hear a verbal response like, “Front door is now locked.”

Note: For security, voice unlocking may be disabled by default. You can only lock the door by voice—not unlock it—unless you enable voice match or PIN verification.

Troubleshooting Common Locking Issues

Even the best smart locks can have hiccups. Here’s how to fix common problems when trying to lock your Eufy security lock.

Lock Won’t Respond to App Commands

  1. Check your Wi-Fi connection. Weak signals can delay commands.
  2. Ensure the lock is within range of your Wi-Fi or hub.
  3. Restart the EufySecurity app.
  4. Reboot your phone.
  5. If the issue persists, try re-pairing the lock in the app.

Tip: Move closer to the door when sending commands to improve signal strength.

Auto-Lock Not Working

  1. Verify auto-lock is enabled in the app.
  2. Check the timer setting—make sure it’s not set too long.
  3. Ensure the lock is fully closed. If the door is ajar, auto-lock may not trigger.
  4. Update the lock’s firmware via the app.

Battery Is Low

Smart locks run on batteries, usually AA or built-in rechargeable packs.

  1. Check the battery level in the EufySecurity app.
  2. If below 20%, replace or recharge the batteries.
  3. Use the physical key or thumb turn to lock manually until replaced.

Warning: Most Eufy locks will beep or flash a red light when batteries are low. Don’t ignore it!

Keypad Not Responding

  1. Clean the keypad with a dry cloth—dirt or moisture can interfere.
  2. Make sure you’re pressing the keys firmly.
  3. Check if the lock is in “sleep mode”—tap any key to wake it up.
  4. Restart the lock by removing and reinserting the batteries.

Best Practices for Using Your Eufy Smart Lock

To get the most out of your Eufy security lock, follow these expert tips.

Keep Firmware Updated

Eufy regularly releases firmware updates to improve performance and security.

  1. Open the EufySecurity app.
  2. Go to your lock’s settings.
  3. Tap “Firmware Update.”
  4. If an update is available, follow the prompts to install it.

Note: Updates may take a few minutes and require the lock to be online.

Create Multiple User Codes

Share access with family, friends, or service providers without giving out your main PIN.

  1. In the app, go to “User Management.”
  2. Tap “Add User” and assign a name.
  3. Set a unique PIN or enable fingerprint (if supported).
  4. Choose access times (e.g., only weekdays 9–5).

Example: Give your dog walker a code that works only on Tuesdays and Thursdays.

Monitor Access Logs

The app keeps a record of every lock and unlock event.

  1. Open the app and select your lock.
  2. Tap “Access Log” or “History.”
  3. View who accessed the door and when.

This is great for security and peace of mind.

Secure Your Wi-Fi Network

Your smart lock is only as secure as your home network.

– Use a strong Wi-Fi password
– Enable WPA3 encryption if available
– Avoid public or shared networks
– Consider a separate guest network for smart devices
