Let’s get started!

Why Change Your Eufy Door Lock Passcode?

Before diving into the steps, it’s worth understanding why changing your passcode matters. Security isn’t just about having a lock—it’s about keeping access under control.

You might want to change your passcode if:
– You’ve given it to someone who no longer needs access (like a former roommate or contractor).
– You suspect someone may have seen or guessed your code.
– You’re setting up temporary access for guests, cleaners, or Airbnb renters.
– You’re moving into a new home and want to start fresh.
– You’ve recently updated your home security system and want consistent access control.

Regularly updating your passcode—especially after major life changes—helps protect your home and gives you peace of mind. Eufy makes this easy with flexible options for permanent, temporary, and one-time use codes.

What You’ll Need Before You Begin

Before changing your passcode, make sure you have the following:

• Admin Access: Only admin users can modify passcodes. If you’re not the admin, ask the primary user to log in or grant you access.
• Eufy Security App: Download it from the App Store (iOS) or Google Play (Android) if you haven’t already.
• Smartphone or Tablet: You’ll need this to use the app or check settings.
• Stable Wi-Fi Connection: Required for syncing changes between the app and your lock.
• Current Passcode or Admin Code: You’ll need this to authenticate changes.
• Fresh Batteries (Optional but Recommended): Low battery can cause sync issues. Check your lock’s battery level in the app.

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

Method 1: Change Passcode Using the Eufy Security App

The Eufy Security app is the most convenient way to manage your lock. It’s user-friendly, secure, and lets you control access from anywhere. Here’s how to use it to change your passcode.

Step 1: Open the Eufy Security App

Launch the app on your smartphone or tablet. Make sure you’re logged in with your admin account. If you’re not the admin, ask the primary user to log in or share access with you.

Step 2: Select Your Door Lock

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

Step 3: Go to Access Management

Tap on the “Access” or “Users & Access” tab. This section manages all passcodes, fingerprints, and smartphone unlock settings.

Step 4: Choose the Passcode to Edit

You’ll see a list of existing passcodes. Each has a name (like “Home,” “Guest,” or “Cleaner”) and a type (permanent, temporary, or one-time). Tap on the passcode you want to change.

Step 5: Edit or Replace the Passcode

Tap “Edit” or “Change Passcode”. Enter your new 4- to 8-digit code. Eufy recommends using a code that’s easy for you to remember but hard for others to guess—avoid sequences like “1234” or “0000.”

Tip: Use a mix of numbers that mean something to you, like a birthday or anniversary, but not something obvious like your house number.

Step 6: Save and Sync

After entering the new code, tap “Save” or “Confirm”. The app will sync the change with your lock. This usually takes a few seconds. You’ll see a confirmation message when it’s done.

Step 7: Test the New Passcode

Go to your door and enter the new passcode on the keypad. The lock should respond with a green light and unlock. If it doesn’t, check your battery or try again.

Pro Tip: If you’re setting up a temporary code for a guest, use the app to set an expiration date. For example, set it to expire after 3 days. This way, access automatically ends—no need to remember to delete it.

Method 2: Change Passcode Using the Keypad (Admin Code Method)

Don’t have your phone handy? No problem. You can change your passcode directly on the Eufy lock’s keypad using the admin code. This method works even without Wi-Fi.

Step 1: Enter Admin Mode

On the keypad, press and hold the “*” key for 3 seconds. The lock will beep and the LED will flash blue, indicating admin mode is active.

Step 2: Enter Your Admin Code

Type in your 6-digit admin code (this is different from your regular passcode). The default admin code is often “123456,” but it should have been changed during setup for security.

If you’ve forgotten your admin code, check the Eufy app under “Device Settings” > “Admin Code.” You can reset it there if needed.

Step 3: Select Passcode Management

After entering the admin code, press “1” to manage user passcodes. The lock will beep to confirm.

Step 4: Choose to Add or Edit a Passcode

Press “2” to edit an existing passcode, or “1” to add a new one. Use the keypad to select the user slot (e.g., User 1, User 2).

Step 5: Enter the New Passcode

Type your new 4- to 8-digit code. Press “#” to confirm. The lock will beep twice to confirm the change.

Step 6: Exit Admin Mode

Press “*” again to exit admin mode. The LED will turn off.

Step 7: Test the New Code

Try unlocking the door with the new passcode. If it works, you’re all set!

Note: This method only allows you to change passcodes for existing users. To add new users or set temporary codes, use the app.

Method 3: Reset All Passcodes (Factory Reset)

If you’ve lost access to your admin code or suspect unauthorized changes, you may need to reset your Eufy lock to factory settings. This will erase all passcodes, fingerprints, and settings—so use it as a last resort.

Step 1: Locate the Reset Button

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

Step 2: Press and Hold the Reset Button

Insert the tool and press the button for 10–15 seconds. The lock will beep and the LED will flash rapidly.

Step 3: Reconfigure the Lock

After resetting, the lock will return to factory settings. You’ll need to:
– Reconnect it to Wi-Fi via the app.
– Set a new admin code.
– Re-add all passcodes and users.

This process takes about 5–10 minutes. Make sure to back up your settings beforehand if possible.

Types of Passcodes on Eufy Locks

Eufy supports different passcode types for flexible access control. Understanding them helps you choose the right one for each situation.

Permanent Passcode

This is your main code for daily use. It doesn’t expire and is ideal for family members or regular users. You can have multiple permanent codes.

Temporary Passcode

Set for a specific time period (e.g., 1 hour, 1 day, 1 week). Perfect for guests, dog walkers, or service providers. Once the time expires, the code stops working.

One-Time Passcode

Works only once. Great for delivery people or one-off visitors. After use, the code becomes invalid.

Admin Code

A 6-digit code used to access admin functions on the keypad. It’s different from your regular passcode and should be kept secure.

Tip: Use the app to assign names to each passcode (e.g., “Mom,” “Cleaner”) so you can easily identify and manage them.

Best Practices for Managing Eufy Passcodes

Changing your passcode is just the first step. To keep your home secure, follow these best practices:

• Change Passcodes Regularly: Update them every 3–6 months or after major life events.
• Use Strong Codes: Avoid obvious sequences. Mix numbers and avoid personal info like birthdays.
• Limit Access: Only give codes to people who truly need them. Revoke access when no longer needed.
• Monitor Activity: Check the app’s access log to see who unlocked the door and when.
• Enable Two-Factor Authentication: In the app settings, turn on 2FA for extra security.
• Keep Batteries Fresh: Low battery can cause sync issues. Replace batteries every 6–12 months.
• Backup Access Methods: Use fingerprint, smartphone unlock, or a physical key as backups.

These habits will help you get the most out of your Eufy lock while keeping your home safe.

Troubleshooting Common Issues

Even with the best setup, things can go wrong. Here’s how to fix common problems when changing your passcode.

Passcode Not Working After Change

If your new code doesn’t unlock the door:
– Wait 30 seconds and try again. Sometimes the lock needs time to sync.
– Check the battery level in the app. Low battery can cause delays.
– Re-enter the code slowly, making sure each digit is pressed firmly.
– If using the app, force-close and reopen it, then re-sync.

App Won’t Sync with Lock

If changes don’t appear on the lock:
– Ensure your phone and lock are on the same Wi-Fi network.
– Restart the app and your phone.
– Check for app updates in the App Store or Google Play.
– Reconnect the lock to Wi-Fi in the app settings.

Forgot Admin Code

If you can’t remember your admin code:
– Check the app under “Device Settings” > “Admin Code.”
– If it’s not there, perform a factory reset (see Method 3).
– Contact Eufy support for assistance.

Keypad Not Responding

If the keypad is unresponsive:
– Clean the keypad with a dry cloth. Dirt or moisture can interfere.
– Replace the batteries.
– Ensure the lock isn’t in sleep mode (press any key to wake it).

Multiple Users Can’t Access

If several users report issues:
– Check if the passcode was deleted or expired.
– Verify user permissions in the app.
– Re-add the passcode if necessary.
