How to Reset Eufy Door Lock

Resetting your Eufy door lock is simple when you follow the right steps. This guide walks you through the process for different models, common issues, and how to restore access safely.

Key Takeaways

• Know your model: Different Eufy locks (e.g., E10, E30, E33) have slightly different reset procedures—always check your user manual or the Eufy app.
• Use the Eufy Security app: Most resets are initiated through the app, which guides you through the process and confirms success.
• Keep your admin code handy: You’ll need your master PIN or admin credentials to start the reset—without it, you may need to perform a factory reset.
• Battery level matters: Ensure your lock has at least 50% battery before resetting to avoid interruptions.
• Factory reset erases all data: This removes all users, codes, and settings—only use it as a last resort.
• Re-pair after reset: Once reset, you’ll need to reconnect the lock to your Wi-Fi and reconfigure access for family or guests.
• Contact support if stuck: If the lock doesn’t respond, Eufy’s customer service can help troubleshoot hardware or software issues.

This comprehensive guide will walk you through the entire process—from identifying your lock model to completing a full factory reset.

By the end, you’ll feel confident handling any reset scenario with ease.

Let’s get started.

Why You Might Need to Reset Your Eufy Door Lock

Before diving into the steps, it’s helpful to understand why a reset might be necessary. Common reasons include:

• Forgotten admin PIN or master code: If you can’t remember the code used to manage the lock, a reset may be the only way to regain control.
• Moving to a new home: When selling or renting a property, it’s crucial to reset the lock to remove previous users and codes.
• Connectivity problems: If your lock keeps disconnecting from the Eufy app or HomeKit, a reset can refresh the connection.
• Software glitches: Occasionally, smart locks freeze or behave unpredictably. A reset often resolves these issues.
• Preparing for a new user: If you’re gifting the lock or setting it up in a new location, a factory reset ensures a clean start.

Resetting your Eufy door lock is not difficult, but it’s important to follow the correct steps for your specific model. Let’s look at how to identify your lock and begin the process.

Step 1: Identify Your Eufy Door Lock Model

Not all Eufy locks are reset the same way. The steps vary slightly depending on whether you have an E10, E30, E33, or another model. Here’s how to find your model:

Check the Lock Itself

Look on the interior side of the lock (the part inside your home). There should be a label or engraved text that includes the model number. Common models include:

• Eufy Smart Lock E10
• Eufy Smart Lock E30
• Eufy Smart Lock E33
• Eufy Smart Lock Touch (various versions)

Use the Eufy Security App

Open the Eufy Security app on your smartphone. Go to Devices, select your door lock, and tap the settings (gear) icon. The model number is usually listed under “Device Info” or “About.”

Check the Original Packaging or Manual

If you still have the box or user manual, the model number will be clearly printed there.

Once you know your model, you can follow the appropriate reset instructions. Most Eufy locks use a similar reset process, but there are key differences—especially between battery-powered and hardwired models.

Step 2: Ensure Your Lock Is Powered On

Before attempting any reset, make sure your Eufy door lock has enough battery power. A low battery can interrupt the reset process and cause errors.

Check Battery Level in the App

Open the Eufy Security app and navigate to your door lock. The battery level is usually displayed on the main device screen. If it’s below 50%, consider replacing the batteries before proceeding.

Use Fresh Batteries

Eufy locks typically use 4 AA batteries. Use high-quality alkaline batteries (like Duracell or Energizer) for best performance. Avoid rechargeable NiMH batteries unless specified, as they may not provide consistent voltage.

Test the Lock Manually

Try locking and unlocking the door using the keypad or physical key. If the motor sounds weak or unresponsive, the battery may be too low.

Pro Tip: Always keep spare batteries on hand. Eufy locks send low-battery alerts, but it’s smart to check periodically—especially before performing a reset.

Step 3: Reset Using the Eufy Security App (Recommended Method)

The easiest and most reliable way to reset your Eufy door lock is through the Eufy Security app. This method preserves your lock’s hardware settings and allows you to reconfigure it quickly.

Open the Eufy Security App

Launch the app on your smartphone. Make sure you’re logged into the account that controls the lock.

Navigate to Your Door Lock

Tap on the Devices tab at the bottom of the screen. Find your door lock in the list and select it.

Access Device Settings

Tap the gear icon (⚙️) in the top-right corner to open the settings menu.

Find the Reset Option

Scroll down until you see an option like “Remove Device” or “Factory Reset.” The exact wording may vary by model.

Confirm the Reset

Tap the reset option and confirm when prompted. The app will guide you through the process, which may include entering your admin PIN or verifying your identity.

Wait for Confirmation

The lock will disconnect from the app and return to its default state. You’ll see a message like “Device removed successfully” or “Reset complete.”

Note: This method only removes the lock from your account. It does not perform a full factory reset on the hardware. To fully erase all data, you may need to proceed with a physical reset (covered below).

Step 4: Perform a Physical Factory Reset (For Full Data Erasure)

If you need to completely wipe the lock—such as when selling your home or troubleshooting persistent issues—a physical factory reset is required. This process varies slightly by model, but here’s a general guide.

Locate the Reset Button

On most Eufy locks, the reset button is a small pinhole on the interior unit. You’ll need a paperclip, SIM tool, or similar thin object to press it.

Common locations:

• E10/E30: Inside the battery compartment, near the bottom.
• E33: On the side of the interior unit, near the USB-C port.
• Touch models: Usually on the back or side, behind a small cover.

Press and Hold the Reset Button

Insert the tool into the pinhole and press firmly. Hold it for 10–15 seconds. You may hear a beep or see a light flash, indicating the reset has started.

Wait for the Lock to Reboot

Release the button and wait. The lock will power cycle, and all lights may flash. This can take 30–60 seconds.

Confirm the Reset

Once the lock restarts, it should return to its factory settings. The keypad may light up in a pattern (e.g., all lights flashing once) to confirm the reset.

Important: A factory reset erases all user codes, fingerprints, access logs, and Wi-Fi settings. You’ll need to set up the lock from scratch.

Step 5: Reconnect Your Eufy Door Lock to the App

After resetting, you’ll need to reconnect the lock to your Eufy account and reconfigure access.

Open the Eufy Security App

Go to the Devices tab and tap the “+” icon to add a new device.

Select “Smart Lock”

Follow the on-screen prompts to add a new lock. The app will search for nearby devices.

Put the Lock in Pairing Mode

On the lock, press and hold the “*” and “#” keys on the keypad for 5 seconds until you hear a beep or see a light flash. This activates pairing mode.

Follow the Setup Wizard

The app will guide you through naming the lock, connecting to Wi-Fi, and setting up your first admin PIN.

Test the Connection

Try locking and unlocking the door using the app. If it works, your reset and reconnection were successful.

Model-Specific Reset Instructions

While the general steps apply to most Eufy locks, here are specific instructions for popular models.

Troubleshooting Common Reset Issues

Even with careful steps, you might run into problems. Here’s how to fix the most common issues.

Lock Doesn’t Respond After Reset

• Check battery level: Replace batteries if below 50%.
• Wait longer: Some locks take up to 2 minutes to fully reset.

App Can’t Find the Lock

• Ensure pairing mode is active: Press “*” and “#” until you hear a beep.
• Restart the app: Close and reopen the Eufy Security app.
• Check Wi-Fi: The lock and phone must be on the same network.

Admin PIN Not Working

• Try the default PIN: Some locks use “123456” or “000000” after a reset.
• Use the physical key: Unlock the door manually, then access the interior unit to reset.
• Contact Eufy support: If all else fails, they can help verify your account and reset remotely.
