Before diving into the locking process, it’s important to understand what you’re working with. Eufy offers several smart lock models, each with unique features but similar core functions. The most popular include:

– Eufy Smart Lock Touch: Features a fingerprint scanner, keypad, and app control.
– Eufy Smart Lock U10: A compact model with keypad and app integration.
– Eufy Smart Lock C22: Budget-friendly with basic keypad and remote access.

All Eufy smart locks are designed to replace your existing deadbolt and integrate with your home’s Wi-Fi network. They allow you to lock and unlock your door without a physical key, using methods like PIN codes, fingerprints, smartphones, or voice commands.

One key advantage of Eufy locks is their local processing—most data stays on the device, not in the cloud, which enhances privacy and reduces lag. However, remote access still requires a stable internet connection and the EufySecurity app.

How to Lock Your Eufy Security Door Manually

Even the smartest locks need a manual backup—and Eufy delivers. If your phone dies, the Wi-Fi goes out, or you just prefer the classic way, you can always lock your door by hand.

Using the Thumb Turn (Inside)

The simplest way to lock your Eufy door is from the inside using the thumb turn—the small lever or knob on the interior side of the lock.

1. Stand inside your home, facing the door.
2. Locate the thumb turn on the interior lock assembly.
3. Rotate it clockwise until it clicks into the locked position.
4. Test the door by gently pulling the handle—it should not open.

This method works instantly and doesn’t require batteries or Wi-Fi. It’s perfect for nighttime locking or when you’re home and want to secure the door quickly.

Using the Keypad (Outside)

If you’re outside and want to lock the door without going in, the keypad is your best friend.

1. Approach your door and wake up the keypad by touching any button.
2. Enter your personal PIN code (e.g., 1234#).
3. Press the lock icon (usually a padlock symbol) or the # key to confirm.
4. The lock will beep or flash to confirm it’s locked.

Pro Tip: Always shield your PIN from view when entering it. Use your body or hand to block the keypad from neighbors or passersby.

Using a Physical Key (Emergency Only)

Every Eufy smart lock comes with a physical key as a backup. This is useful during power outages or if the lock malfunctions.

1. Locate the keyhole on the exterior of the lock (usually hidden under a cover).
2. Insert the key and turn it clockwise to lock.
3. Remove the key and store it safely.

Note: Only use the physical key in emergencies. Frequent use can wear out the internal mechanism.

How to Lock Your Eufy Door Using the EufySecurity App

The EufySecurity app is the heart of your smart lock experience. It lets you control your door from anywhere, monitor access, and customize settings.

2. Select your lock model from the list.
3. Follow the pairing process—this usually involves scanning a QR code on the lock or entering a setup code.
4. Connect the lock to your home Wi-Fi network.
5. Name your lock (e.g., “Front Door”) for easy identification.

Once paired, your lock will appear in the app dashboard.

Step 2: Lock the Door Remotely

Now that your lock is connected, locking it remotely is simple.

You can do this from your couch, your office, or even while on vacation—anywhere with internet access.

Step 3: Enable Auto-Lock for Hands-Free Security

One of the best features of Eufy locks is auto-lock. This automatically secures your door after a set time, so you never have to worry about forgetting.

1. Open the EufySecurity app.
2. Go to your lock’s settings (tap the gear icon).
3. Find “Auto-Lock” and toggle it on.
4. Set the delay time (e.g., 30 seconds, 1 minute, 5 minutes).
5. Save your settings.

Now, every time you unlock the door, it will automatically lock itself after the chosen time. Perfect for busy families or forgetful moments.

How to Lock Your Eufy Door with Voice Commands

Pro Tip: You can also ask, “Is the front door locked?” to check its status without touching your phone.

How to Lock Your Eufy Door with a Fingerprint (Touch Models Only)

If you have a Eufy Smart Lock Touch, you can use your fingerprint to lock the door—no PIN or phone needed.

Step 1: Register Your Fingerprint

2. The lock will recognize you and automatically lock the door.
3. A green light or beep confirms success.

This method is fast, secure, and keyless—perfect for quick exits.
