How to Change Eufy Door Lock Password

Changing your Eufy door lock password is simple and essential for home security. This guide walks you through the process using the Eufy app, physical keypad, or manual override—ensuring your smart lock stays up to date and protected.

Key Takeaways

• Use the Eufy Security app for the easiest password change: Most Eufy smart locks integrate seamlessly with the app, allowing quick and secure updates from your smartphone.
• Always test your new password immediately: After changing the code, verify it works to avoid lockouts or security gaps.
• Keep a backup access method ready: Ensure you have a physical key, admin code, or temporary guest code in case of app or battery issues.
• Update passwords regularly for better security: Experts recommend changing your door lock code every 3–6 months or after major life events like moving in or out.
• Know your lock model: Different Eufy models (like the Eufy Smart Lock Touch or Eufy Smart Lock Fingerprint) may have slight variations in the password change process.
• Low battery can affect functionality: If your lock isn’t responding, check the battery level—weak power may prevent password updates.

How to Change Eufy Door Lock Password

Keeping your home secure starts with controlling who can enter—and one of the simplest yet most effective ways to do that is by regularly updating your door lock password. If you’ve recently moved in, had a service person over, or just want to refresh your access codes, knowing how to change your Eufy door lock password is essential. The good news? It’s easier than you think.

In this comprehensive guide, we’ll walk you through every method available to update your Eufy smart lock password—whether you’re using the Eufy Security app, the physical keypad on the lock, or even a manual override. We’ll also cover troubleshooting tips, security best practices, and answers to common questions so you can stay in control of your home’s access at all times.

Whether you’re a first-time smart lock user or just need a refresher, this step-by-step tutorial will ensure you can change your Eufy door lock password confidently and correctly—without calling a locksmith.

Why Changing Your Eufy Door Lock Password Matters

Before diving into the how-to, let’s talk about the why. Your door lock password is the first line of defense against unauthorized entry. Over time, people may have had access—cleaners, guests, contractors, or even former roommates. Even if you trust them, it’s smart to rotate your codes periodically to minimize risk.

Smart locks like Eufy offer convenience and advanced security features, but they’re only as strong as the passwords protecting them. A weak or reused code can be guessed or shared unintentionally. By changing your password regularly, you reduce the chance of someone gaining access without your knowledge.

Additionally, Eufy locks often support multiple user codes, temporary access for guests, and remote management via the app. This flexibility is great, but it also means more opportunities for codes to fall into the wrong hands. Regular updates help you maintain control and peace of mind.

What You’ll Need Before You Begin

Before changing your Eufy door lock password, make sure you have the following:

• Your smartphone with the Eufy Security app installed: This is the primary tool for managing most Eufy smart locks.
• Admin access to the lock: Only the admin user (usually the person who set up the lock) can change passwords or manage user codes.
• A stable Wi-Fi or Bluetooth connection: Required for syncing changes between the app and the lock.
• Fresh batteries (if applicable): Low battery can cause the lock to malfunction or reject new codes.
• Your current admin code or master password: Needed to authenticate changes.
• A backup access method: Such as a physical key or a temporary guest code, in case something goes wrong.

Having these items ready will make the process smooth and stress-free.

Method 1: Changing Your Password via the Eufy Security App

The Eufy Security app is the most convenient and recommended way to change your door lock password. It gives you full control over user codes, access logs, and security settings—all from your phone.

Step 1: Open the Eufy Security App

Launch the Eufy Security app on your smartphone. Make sure you’re logged into the account that has admin access to the lock. If you’re not the admin, you’ll need permission from the person who set up the device.

Step 2: Select Your Smart Lock

On the home screen, tap on the device icon for your Eufy smart lock. It should appear with a live status indicator (e.g., “Locked” or “Unlocked”). If you have multiple locks, choose the correct one.

Step 3: Navigate to User Management

Once inside the lock’s control panel, look for a menu option labeled “User Management,” “Access Codes,” or “User Codes.” This is where you can view, add, or delete passwords.

Step 4: Choose the Code to Change

You’ll see a list of existing user codes. Tap on the one you want to update—this could be your personal code, a guest code, or a temporary access code. If you’re changing your own admin code, select it from the list.

Step 5: Edit or Replace the Password

Tap “Edit” or “Change Code.” You’ll be prompted to enter a new 4- to 8-digit numeric password. Choose something secure but memorable—avoid obvious sequences like “1234” or “0000.”

Pro Tip: Use a code that’s meaningful to you but hard for others to guess, like the last four digits of a childhood phone number or a favorite date.

Step 6: Confirm the New Password

Re-enter the new code to confirm it. The app will sync the change with your lock. You may see a brief loading screen or a confirmation message like “Code Updated Successfully.”

Step 7: Test the New Password

Go to your front door and enter the new code on the keypad. The lock should respond immediately—either unlocking or confirming the code is active. If it doesn’t work, double-check the code in the app and try again.

Optional: Set Expiration or Permissions

For guest codes, you can set time limits (e.g., valid for 24 hours) or restrict access to certain days. This is especially useful for Airbnb hosts or cleaning services.

Method 2: Changing Your Password Using the Physical Keypad

Not all Eufy models support on-device password changes, but some—like the Eufy Smart Lock Touch—allow you to update codes directly from the keypad. This method is helpful if your phone battery dies or the app isn’t working.

Step 1: Enter Admin Mode

Stand in front of your Eufy lock and press the “*” key followed by your current admin code, then press “#”. This puts the lock into programming mode. You should hear a beep or see a light flash to confirm.

Step 2: Select User Code Option

Press “2” to access user code settings. The lock will prompt you to choose which user code to modify (e.g., User 1, User 2, etc.).

Step 3: Enter the New Password

Type in your new 4- to 8-digit code, then press “#” to confirm. The lock will beep or flash to indicate success.

Step 4: Exit Admin Mode

Press “*” again to exit programming mode. The new code is now active.

Note: This method varies slightly by model. Check your user manual for exact key sequences. If you’re unsure, use the app method instead.

Method 3: Resetting All Codes (Factory Reset)

If you’ve lost access to your admin code or suspect someone else knows it, you may need to perform a factory reset. This erases all user codes and returns the lock to its original settings.

Warning: A factory reset will delete all existing codes, including your admin code. You’ll need to set everything up again from scratch.

Step 1: Locate the Reset Button

Most Eufy locks have a small reset button inside the battery compartment. Remove the battery cover and look for a tiny hole labeled “Reset.”

Step 2: Press and Hold the Reset Button

Use a paperclip or SIM tool to press and hold the reset button for 5–10 seconds. You’ll hear a series of beeps or see the LED flash rapidly.

Step 3: Reconfigure the Lock

Once reset, the lock will be in pairing mode. Open the Eufy app, remove the old device (if still listed), and follow the setup process to add it again. Create a new admin code during setup.

Step 4: Add New User Codes

After setup, add your personal code and any guest codes using the app or keypad method.

Pro Tip: Only use a factory reset as a last resort. It’s time-consuming and should only be done if you can’t access the lock through normal means.

Best Practices for Eufy Door Lock Passwords

Now that you know how to change your password, let’s talk about how to keep it secure.

• Use unique codes for each user: Avoid sharing the same code with multiple people. Unique codes let you track who accessed the lock and revoke access individually.
• Avoid obvious sequences: Steer clear of “1234,” “0000,” or repeating numbers. These are the first combinations attackers try.
• Change codes after major events: Update passwords after moving in, ending a lease, or when a guest’s visit ends.
• Enable auto-lock: Set your lock to automatically re-engage after 30 seconds to prevent accidental entry.
• Monitor access logs: Use the Eufy app to review who unlocked the door and when. This helps detect suspicious activity.
• Keep firmware updated: Regularly check for app and lock firmware updates to ensure you have the latest security patches.

Troubleshooting Common Issues

Even with the best preparation, things can go wrong. Here’s how to fix the most common problems when changing your Eufy door lock password.

Issue: App Won’t Sync the New Code

If the app says the code was updated but the lock doesn’t respond, try the following:

• Ensure your phone is connected to Wi-Fi or Bluetooth.
• Move closer to the lock to improve signal strength.
• Restart the Eufy app and try again.
• Check if the lock’s firmware is up to date in the app settings.

Issue: Keypad Not Responding

If the keypad is unresponsive when entering a new code:

• Check the battery level—low power can cause lag or failure.
• Clean the keypad with a dry cloth to remove dirt or moisture.
• Ensure you’re pressing the keys firmly and waiting for feedback (beep or light).

Issue: Forgotten Admin Code

If you’ve forgotten your admin code and can’t access the app:

• Use the physical key (if your model includes one) to unlock the door.
• Perform a factory reset as described above.
• Contact Eufy customer support for assistance—they may require proof of purchase.

Issue: New Code Doesn’t Work

If the new password fails to unlock the door:

• Double-check the code in the app—typos happen.
• Wait a few minutes—some locks take time to sync.
• Try the old code to see if the lock is malfunctioning.
• Reset the code again using the app.

Security Tips for Eufy Smart Lock Users

Your Eufy lock is smart, but it’s only as secure as your habits. Follow these tips to maximize protection:

• Enable two-factor authentication (2FA): In the Eufy app, go to Account Settings > Security > Two-Factor Authentication. This adds an extra layer of protection against unauthorized app access.
• Don’t share your admin code: Only trusted family members should know the main password. Use guest codes for others.
• Disable remote unlock if not needed: If you don’t use the app to unlock from afar, turn off this feature to reduce hacking risks.
• Use strong Wi-Fi security: Ensure your home network is protected with WPA3 encryption and a strong password.
• Regularly review user codes: Delete old or unused codes to minimize exposure.

Conclusion

Changing your Eufy door lock password is a quick, simple task that plays a big role in keeping your home safe. Whether you use the Eufy Security app, the physical keypad, or need to reset the entire system, you now have the tools and knowledge to manage your access codes with confidence.

Remember: security isn’t a one-time setup—it’s an ongoing practice. Update your passwords regularly, monitor access logs, and stay informed about your lock’s features. With Eufy’s smart technology and your proactive habits, you can enjoy both convenience and peace of mind.

So go ahead—change that password today. Your future self (and your front door) will thank you.
