How to Reset Eufy Lock

Resetting your Eufy lock is simple when you follow the right steps. This guide walks you through the process for all major Eufy models, including troubleshooting and safety tips. Get your smart lock back to factory settings in minutes.

Key Takeaways

• Know your model: Different Eufy locks (like the E10, E110, or S330) have slightly different reset procedures—always check your model first.
• Use the Eufy app: Most resets are done through the EufySecurity app, which guides you through the process safely.
• Factory reset vs. user reset: A factory reset erases all data and returns the lock to original settings, while a user reset may only clear access codes.
• Power matters: Ensure your lock has sufficient battery before starting—low power can interrupt the reset.
• Re-pair after reset: After a reset, you’ll need to reconnect the lock to your Wi-Fi and reconfigure settings in the app.
• Keep the manual handy: The user manual or Eufy’s support site has model-specific instructions if you get stuck.
• Contact support if needed: If the reset fails, Eufy’s customer service can help with advanced troubleshooting.

How to Reset Eufy Lock: A Complete Step-by-Step Guide

So, you’ve decided it’s time to reset your Eufy smart lock. Maybe you’re moving to a new home, giving the lock to someone else, or troubleshooting a glitch. Whatever the reason, resetting your Eufy lock is a smart move—and it’s easier than you might think.

In this guide, we’ll walk you through how to reset Eufy lock safely and effectively, covering all the major models, common pitfalls, and pro tips to make the process smooth. Whether you’re using the Eufy E10, E110, S330, or another model, this guide has you covered. By the end, you’ll know exactly what to do—and what to avoid—so your smart lock works like new again.

Why Reset Your Eufy Lock?

Before we dive into the steps, let’s talk about why you might need to reset your Eufy lock. Understanding the reason helps you choose the right type of reset and avoid unnecessary complications.

Common reasons include:

• Moving to a new home: You want to erase all previous access codes and user data before handing over the lock to a new owner or tenant.
• Selling or gifting the lock: A factory reset ensures your personal information isn’t left behind.
• Technical issues: If the lock is unresponsive, freezing, or not connecting to the app, a reset can often fix the problem.
• Changing Wi-Fi network: Sometimes a reset is needed to reconnect the lock to a new router or network.
• Security concerns: If you suspect someone unauthorized has access, resetting removes all existing codes and permissions.

No matter your reason, a proper reset gives you a clean slate. But remember: a reset is permanent. Once you erase the data, you can’t get it back unless you’ve backed it up (which Eufy doesn’t currently support). So make sure you’re ready before you begin.

Types of Eufy Lock Resets

Not all resets are the same. Eufy locks support different types of resets, and it’s important to know which one you need.

User Reset (Soft Reset)

A user reset clears access codes, fingerprints, and user permissions but keeps the lock’s network settings and firmware intact. This is useful if you just want to remove old users or codes without starting over completely.

For example, if your teenager moved out and you want to delete their fingerprint, a user reset might be enough. But if you’re moving or selling the lock, you’ll need a full factory reset.

Factory Reset (Hard Reset)

A factory reset wipes everything: access codes, fingerprints, user accounts, Wi-Fi settings, and app pairings. It returns the lock to its original out-of-the-box state. This is the most thorough reset and is recommended when transferring ownership or troubleshooting serious issues.

Most people searching “how to reset Eufy lock” are looking for a factory reset. That’s what we’ll focus on in this guide, but we’ll also cover user resets where applicable.

Before You Reset: Important Preparations

Resetting your Eufy lock isn’t risky, but a little prep can save you time and frustration. Here’s what to do before you start:

1. Check Your Battery Level

Your Eufy lock runs on batteries—usually AA or lithium. A low battery can cause the reset to fail or the lock to shut down mid-process. Check the battery level in the EufySecurity app or on the lock’s display (if it has one).

If the battery is below 20%, replace it before resetting. Use high-quality alkaline or lithium batteries for best performance. Avoid rechargeable NiMH batteries unless specified by Eufy, as they may not provide consistent voltage.

2. Ensure Stable Wi-Fi Connection

Even though the reset process happens on the lock itself, you’ll need the Eufy app to initiate it—and that requires a stable internet connection. Make sure your phone is connected to the same Wi-Fi network as your lock.

If your Wi-Fi is spotty, move closer to the router or restart it. A weak signal can delay or interrupt the reset.

3. Have Your Phone and App Ready

You’ll need the EufySecurity app (available on iOS and Android) to guide the reset. Make sure it’s updated to the latest version. Older versions may not support newer lock models or reset features.

Also, ensure your phone is charged. You don’t want it dying halfway through the process.

4. Know Your Lock Model

Eufy makes several smart lock models, and the reset steps can vary slightly. The most common include:

• Eufy E10 (Wi-Fi Smart Lock)
• Eufy E110 (Wi-Fi Smart Lock with Keypad)
• Eufy S330 (Smart Lock with Fingerprint)
• Eufy Smart Lock F1 (Fingerprint + Keypad)

Check the label on the back of your lock or in the app under “Device Info” to confirm your model. This ensures you follow the correct steps.

5. Back Up Important Information (If Possible)

Unfortunately, Eufy doesn’t offer a way to back up your lock settings. But you can manually note down:

• Your current access codes
• User names and permissions
• Wi-Fi network name and password
• Any custom settings (like auto-lock delay)

This makes reconfiguring the lock after the reset much faster.

How to Reset Eufy Lock: Step-by-Step Instructions

Now that you’re prepared, let’s get into the actual reset process. We’ll cover the most common Eufy models, but the steps are similar across the board.

Method 1: Reset via the EufySecurity App (Recommended)

This is the easiest and safest way to reset your Eufy lock. The app guides you through each step and confirms when the reset is complete.

Step 1: Open the EufySecurity App

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

Step 2: Select Your Lock

On the home screen, tap on the lock you want to reset. It should show up as an active device.

Step 3: Go to Device Settings

Tap the gear icon (⚙️) or “Settings” button, usually located in the top-right corner of the device screen.

Step 4: Find the Reset Option

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

Step 5: Confirm the Reset

The app will warn you that this action cannot be undone. Tap “Confirm” or “Reset” to proceed. You may be asked to enter your account password for security.

Step 6: Wait for the Process to Complete

The lock will restart and reset itself. This usually takes 30–60 seconds. You’ll see a message in the app when it’s done.

Step 7: Reconnect the Lock

After the reset, the lock will be disconnected from your account. You’ll need to set it up again as if it were new. Follow the app’s on-screen instructions to re-pair it with your Wi-Fi and configure settings.

Tip: If the app doesn’t show a reset option, your lock model may require a physical reset. See Method 2 below.

Method 2: Physical Reset Using the Reset Button

Some Eufy locks have a small reset button on the interior side (the part inside your home). This method is useful if the app isn’t working or you can’t access your account.

Step 1: Locate the Reset Button

Remove the interior cover of the lock (usually by unscrewing two screws). Look for a small hole labeled “Reset” or a tiny button near the battery compartment.

Step 2: Use a Paperclip or SIM Tool

Straighten a paperclip or use a SIM ejector tool. Gently insert it into the reset hole and press the button inside.

Step 3: Hold for 5–10 Seconds

Press and hold the reset button for about 5–10 seconds. You may hear a beep or see a light flash, indicating the reset has started.

Step 4: Wait for the Lock to Restart

Release the button and wait. The lock will power cycle and return to factory settings. This may take up to a minute.

Step 5: Reconnect via the App

Once the lock restarts, open the EufySecurity app and follow the setup process to reconnect it to your account and Wi-Fi.

Note: Not all Eufy models have a physical reset button. Check your user manual or Eufy’s support page to confirm.

Method 3: Reset via Keypad (For Models with Keypad)

Some Eufy locks, like the E110 or Smart Lock F1, allow you to reset directly from the keypad. This is handy if you don’t have your phone nearby.

Step 1: Enter Admin Mode

On the keypad, enter your admin code (the master code used to manage the lock). Then press the “*” or “#” key, depending on your model.

Step 2: Navigate to Reset Option

Use the keypad to scroll through menu options. Look for “Factory Reset” or “Restore Defaults.”

Step 3: Confirm the Reset

Follow the on-screen prompts to confirm. You may need to enter the admin code again.

Step 4: Wait and Reconnect

The lock will reset and restart. Afterward, use the app to reconnect and reconfigure.

Tip: If you’ve forgotten your admin code, you may need to use the physical reset method or contact Eufy support.
