Let’s get started!

Understanding Your Eufy Lock

Before we dive into the how-to, let’s quickly go over what makes Eufy locks special. Eufy (a brand under Anker) focuses on privacy and local storage—your data stays on the device, not in the cloud. That means faster response times and better security.

Most Eufy locks feature:
– A built-in keypad for code entry
– A thumbturn for manual operation
– Fingerprint scanning (on select models)
– Bluetooth and Wi-Fi connectivity
– Rechargeable battery with long life

Knowing these components will help you understand how each locking method works. For example, the thumbturn lets you lock the door from the inside without any tech involved. The keypad allows you to enter a code to lock or unlock. And the app gives you remote control.

Now, let’s explore the different ways to lock your Eufy lock.

Method 1: Locking Eufy Lock Manually

Sometimes, the simplest method is the best. Manual locking doesn’t require Wi-Fi, an app, or even battery power. It’s perfect for when you’re right at the door and want to secure it quickly.

Using the Thumbturn

The thumbturn is the small lever or knob on the interior side of your Eufy lock. It’s the most straightforward way to lock your door from inside.

Here’s how to do it:

1. Stand inside your home, facing the door.
2. Locate the thumbturn on the lock body—it’s usually on the side or front of the lock.
3. Rotate the thumbturn clockwise until it stops. You’ll feel a solid click.
4. The lock is now engaged. The deadbolt should be fully extended into the door frame.

That’s it! This method works every time, even during a power outage or if the battery dies. It’s a mechanical backup that ensures your home stays secure.

Using the Keypad (From Outside)

If you’re outside and want to lock the door after leaving, the keypad is your go-to tool.

Follow these steps:

1. Stand in front of your door with the keypad visible.
2. Press the lock button (usually marked with a padlock icon or the word “LOCK”).
3. Wait for the lock to respond—most models will beep or flash a light to confirm.
4. The deadbolt will extend, locking the door.

Some Eufy models allow you to lock by entering your code and pressing the lock button. For example:
– Enter your 6-digit code.
– Press the lock button immediately after.

This adds an extra layer of security, ensuring only authorized users can lock or unlock the door.

Pro Tip: Check the Lock Status

After locking manually, give the door a gentle tug to confirm it’s secure. If it opens, the deadbolt may not have fully extended. Try locking again or check for obstructions in the strike plate.

Method 2: Locking Eufy Lock 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, monitor access, and manage settings.

Download and Set Up the App

If you haven’t already, download the Eufy Security app from the Apple App Store or Google Play Store. Create an account and follow the setup wizard to pair your lock.

Once connected, you’ll see your lock on the home screen.

Locking via the App

Here’s how to lock your Eufy lock remotely:

1. Open the Eufy Security app on your smartphone.
2. Tap on your lock from the device list.
3. Look for the lock icon—it usually shows whether the door is locked or unlocked.
4. Tap the lock icon to change the status. If it’s unlocked, tapping it will lock the door.
5. Wait a few seconds for the command to process. You’ll see a confirmation message and hear the lock engage (if you’re nearby).

The app uses Bluetooth or Wi-Fi to communicate with your lock. If you’re at home, Bluetooth works instantly. If you’re away, Wi-Fi ensures the command goes through.

Example: Locking While on Vacation

Imagine you’re on a beach in Bali and suddenly remember you left the front door unlocked. No problem! Open the app, tap your lock, and secure your home in seconds. You’ll get a notification confirming the lock status.

Pro Tip: Enable Notifications

Turn on push notifications in the app settings. That way, you’ll be alerted whenever someone locks or unlocks the door—great for monitoring kids, guests, or service workers.

Method 3: Using Voice Commands

Want to lock your door without lifting a finger? Voice control makes it possible with Amazon Alexa or Google Assistant.

Set Up Voice Control

First, link your Eufy account to your smart assistant:

1. Open the Alexa or Google Home app.
2. Go to Skills & Games (Alexa) or Add (+) > Set up device (Google).
3. Search for “Eufy Security” and enable the skill.
4. Log in with your Eufy account credentials.
5. Discover devices. Your lock should appear in the list.

Once connected, you can use voice commands.

Locking with Voice

Try these commands:
– “Alexa, lock the front door.”
– “Hey Google, lock the Eufy lock.”

The assistant will confirm the action, and your door will lock. You’ll also get a voice response like, “Front door is now locked.”

Important Note: Security First

For safety, most Eufy locks require a voice PIN for locking via voice. This prevents unauthorized users from locking your door. Set up a PIN in the Eufy app under voice settings.

Method 4: Auto-Lock Feature

Forgot to lock the door again? The auto-lock feature has your back. It automatically engages the deadbolt after a set period, so you never have to worry.

Enable Auto-Lock in the App

Here’s how to turn it on:

1. Open the Eufy Security app.
2. Tap your lock, then go to Settings.
3. Find “Auto-Lock” or “Auto Lock Timer.”
4. Toggle it on and choose a time delay—options usually range from 30 seconds to 5 minutes.
5. Save your settings.

Now, whenever you unlock the door (manually or via app), the lock will automatically re-engage after the chosen time.

Example: Perfect for Families

If you have kids who often forget to lock the door, auto-lock ensures your home stays secure. Even if they rush out without locking, the door will secure itself in two minutes.

Pro Tip: Adjust Based on Routine

If you’re home all day, set a longer delay (like 5 minutes). If you’re frequently in and out, 30–60 seconds works well.

Method 5: Locking with Fingerprint (Select Models)

Some Eufy locks, like the Smart Lock Touch, include a fingerprint scanner. This is one of the fastest and most secure ways to lock your door.

How to Use Fingerprint Locking

After unlocking with your fingerprint, the lock may automatically re-engage when you close the door. Or, you can manually lock it by:

1. Place your registered finger on the scanner.
2. Wait for the green light or beep.
3. The lock will engage the deadbolt.

Check your model’s manual to confirm if this feature is available.

Pro Tip: Register Multiple Fingers

Add fingerprints for different fingers (thumb, index) to make access easier, especially if your hands are full.

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 lock.

Lock Won’t Respond

If the lock doesn’t react when you press the button or use the app:
– Check the battery level in the app. Low power can cause delays.
– Recharge or replace the battery if needed.
– Ensure the lock is within Bluetooth or Wi-Fi range.

Deadbolt Doesn’t Extend Fully

If the lock seems to engage but the door still opens:
– Inspect the strike plate on the door frame. It may be misaligned.
– Adjust the strike plate or tighten the screws.
– Lubricate the deadbolt with graphite powder (never oil—it attracts dirt).

App Says “Offline”

If you can’t lock remotely:
– Make sure your home Wi-Fi is working.
– Restart the lock by removing and reinserting the battery.
– Reconnect the lock to the app via the setup process.

False Lock Alerts

Sometimes the app says the door is locked when it’s not. This can happen if the sensor is dirty.
– Clean the lock’s internal sensor with a dry cloth.
– Ensure the deadbolt fully retracts and extends during testing.

Maintenance Tips for Reliable Locking

To keep your Eufy lock working smoothly, follow these simple maintenance steps:

Check Battery Monthly

The app shows battery level, but it’s good to check physically every month. Replace or recharge before it drops below 20%.

Clean the Keypad and Scanner

Dirt and grime can interfere with touch response. Wipe the keypad and fingerprint scanner with a microfiber cloth weekly.

Test the Lock Weekly

Lock and unlock the door using different methods to ensure everything works. This helps catch issues early.

Update Firmware

Eufy releases updates to improve performance and security. Enable auto-updates in the app or check manually every few months.

Security Best Practices

Locking your door is just one part of home security. Follow these tips to stay safe:

Use Strong Codes

Avoid simple codes like “123456” or “000000.” Choose a unique 6-digit number and change it every few months.

Limit Guest Access

When giving codes to visitors, use temporary codes that expire after a set time. Delete them when no longer needed.

Monitor Access Logs

Check the app’s activity log regularly. See who locked or unlocked the door and when.

Disable Auto-Lock When Needed

If you’re having work done at home, turn off auto-lock temporarily to avoid constant re-engagement.

Conclusion

Knowing how to lock Eufy lock gives you peace of mind and full control over your home’s security. Whether you’re using the thumbturn, the app, voice commands, or auto-lock, Eufy makes it simple and reliable.
