  • 2K camera
  • USB-C charging port
  • PIR motion sensor
  • Radar motion detection

This device offers multiple ways to lock and unlock your door, making it a convenient and secure choice for your home.

What's included

Before starting the installation, ensure you have all the necessary components:

Installing the Eufy app

  3. Navigate to "Add a device."
  4. Select "Smart locks" and then "Video Smart Lock."
  5. Assign the lock to the relevant home location.
  6. Scan the QR code on the back of the lock's exterior housing to begin the pairing process.

The app will guide you through the initial setup, providing essential information for the hardware installation

Hardware installation

  1. Begin by removing the original thumbturn, plate, and deadbolt from your door.
  2. Ensure the "Top" label on the Eufy deadbolt is upright and set to the correct size (2 ⅜" or 2 ¾").
  3. Replace the original deadbolt with the Eufy deadbolt if it fits flush with your door. If not, you can use your existing deadbolt.
  4. Secure the deadbolt with the screws included in the Eufy kit.
  5. Insert the lock's exterior part into place, ensuring the wires are tucked under the deadbolt.
  6. Slide the turn bar through the hole in the center.

Mounting plate

  1. Add the mounting plate, ensuring the silicone side is against the door.
  2. Pass the wires from the exterior piece through the middle hole of the plate.
  3. Thread the long bolts provided in your Eufy kit through the mounting plate and deadbolt and into the exterior lock part.

Interior piece

  1. Slide off the cover of the interior lock piece and keep the battery nearby.
  2. Connect the wires as instructed, ensuring the correct connections.
  3. Secure the interior piece to the door using the small screws from the kit.

  5. Insert the battery into the smart lock and wait for the voice prompt.

App setup

  1. Complete the setup in the Eufy app by following the instructions.
  2. If you didn't start the pairing process earlier, select "Smart locks" and then "Video Smart Lock" in the app.
  3. Indicate that you have finished the physical installation.
  4. Choose whether to connect the lock to your home Wi-Fi network or a Eufy HomeBase 3.
  5. Follow the on-screen instructions to connect to your network.
  6. Select a location for your lock, either from the provided options or by creating your own.
  7. Calibrate the lock by letting it move into place (adjust if necessary).
  8. Create a 4 to 8-digit PIN code, scan your fingerprints, and configure night vision optimization.
