Follow the on-screen instructions in the Wi-Fi Settings section on the eufy Security app to connect and pair your phone with Smart Lock Touch & Wi-Fi. Once successfully paired, you can operate the Smart Lock Touch & Wi-Fi even when you're outside your home.

Note: Make sure you add Smart Lock Touch & Wi-Fi to the device list on the eufy Security app before pairing it with your phone via Wi-Fi.

Works with the Google Assistant / Amazon Alexa

The Smart Lock Touch & Wi-Fi can work with the Google Assistant / Amazon Alexa app. With Google Home or Amazon Alexa devices at home, you can lock or unlock the door using voice commands.

Note:

• Make sure you've downloaded the Google Assistant or Amazon Alexa app on your phone.
• Make sure your Google Home or Amazon Alexa devices are connected to the network.

Installing the Smart Lock Touch & Wi-Fi

Prepare Door for Installation

Ensure the following criteria are met for proper installation:

• Check the door status and ensure the doorframe is aligned with the door.
• Ensure there are no obstructions in the doorframe.
• Leave enough space for the deadbolt to extend into the doorframe when the door is locked.

Check your door/frame dimensions to ensure they fit the following measurements:

• Cross bore diameter: 2⅛" / 54 mm or 1½" / 38 mm
• Backset: 2⅜" / 60 mm or 2¾" / 70 mm
• Door hole diameter: 1" / 25 mm
• Door thickness: 1⅜" / 35 mm - 2" / 55 mm

If you have an existing lock, remove it, including the bolt.

Step 1: Install the Deadbolt

To install the deadbolt:

1. Measure your door's backset dimension: 2⅜" / 70 mm or 2⅜" / 60 mm.
2. If your door's backset is 2⅜" / 60 mm, use the provided deadbolt. If it's 2¾" / 70 mm, turn the faceplate 180° and pull to extend the deadbolt until it locks in position.
3. Insert the deadbolt into the doorframe with the word "TOP" facing up.
4. Screw into the doorframe with a screwdriver (not provided).

Step 2: Install the Strike Plate

If you have an existing strike plate installed, skip this step.

To install the strike plate:

1. Align the strike plate with the center hole of the deadbolt.
2. Secure the strike plate with strike screws, ensuring correct direction.

To enhance security, install the strike reinforcer first:

1. Attach the strike reinforcer on the doorframe and tighten the reinforcement screws with a screwdriver (not provided).

Note: This step is necessary to maintain BHMA Grade 2 security. You can install the strike plate directly if desired.

Step 3: Install the Exterior Assembly

To install the exterior assembly into the doorframe:

1. Measure your cross bore dimension and determine installation steps. Use the provided spacer for a 2" / 54 mm cross bore, or remove it for a 1½" / 38 mm crossbore.
2. Route the cable from the exterior assembly under the deadbolt.
3. Align the tailpiece with the center hole of the deadbolt and insert it into the center hole.

Step 4: Install the Mounting Plate

1. Route the cable through the mounting plate.
2. Fix the mounting plate onto the interior doorframe using the mounting plate screws. Ensure screws go through the deadbolt and mounting plate holes to lock in place.
3. Option A: If the mounting plate fits perfectly, proceed to Step 5.
4. Option B: If the mounting plate is not fastened tightly, use an additional screw.

Step 5: Install the Interior Assembly

To install the Interior Assembly:

1. Remove the battery cover.
2. Match the wire connector from the circuit board with the one from the interior assembly. Ensure correct alignment (dot on connector to pin on circuit board).
3. Align the tailpiece with the key cylinder.
4. Secure the provided screws into the interior assembly.
5. Turn the thumbturn to check if the deadbolt retracts smoothly. Adjust screws if necessary.
6. Use the plug to cover the screw hole at the bottom of the Smart Lock Touch & Wi-Fi.

Note: Check carefully whether the wire is stuck or tangled. If it is, re-install the Interior Assembly.

Step 6: Install the Battery

Align the pin connector on the battery with the pin and slide the battery into the battery compartment.

You are all set! Follow the in-app instructions to set up the Smart Lock Touch & Wi-Fi.

Note: Do not close the battery cover yet. This allows access to the QR code for information and the Setup button.

Setting Up the Smart Lock Touch & Wi-Fi

Pair Your Phone with Smart Lock Touch & Wi-Fi

Note: The lock will not lock automatically before setup is complete. To avoid being locked out, pair your phone and set an access code.

To pair your phone:

1. Scan the QR code on the back of the Smart Lock Touch & Wi-Fi for Bluetooth information. Follow on-screen instructions to complete setup.
2. Pair your phone with the Smart Lock Touch & Wi-Fi via Bluetooth. Your phone will search for the Smart Lock Touch & Wi-Fi's Bluetooth and connect.

Note:

• Waiting to pair: LED indicator flashes blue.
• Paired: LED indicator turns steady blue for 5 seconds.
• The paired user is the sole administrator and can authorize other users.
• Pressing and holding the Setup button resets the lock to default settings. All settings will be erased. Avoid this unless necessary.

Calibrate Smart Lock Touch & Wi-Fi

Once paired, the eufy Security app will prompt you to calibrate the door lock. Ensure the door is closed before calibrating. The door sensor records the locked position for automatic locking.

Follow the on-screen instructions to complete calibration.

• Successfully calibrated: The button LED turns white for 2 seconds, then off. Voice prompt: "calibration complete".
• Fail to calibrate: The button and status LED turn solid red for 2 seconds, then off. Voice prompt: "The deadbolt is stuck. Please return to the installation, and try again."

Note: If calibration fails, check the door installation and try again.

Set Access Code

After calibration, the eufy Security app will prompt you to name your Smart Lock Touch & Wi-Fi and set an access code (4-8 characters). Follow on-screen instructions.

Note: If you click "Return" without setting a passcode, an "initialization unsuccessful" message will appear. Click the card to access the Smart Lock Touch & Wi-Fi page where you can "Continue or remove the device".

Set Scramble Passcode

A scramble passcode is a series of random numbers to prevent others from spying on your access code. It's useful in shared living spaces. Set a scramble passcode (up to 12 digits) in the eufy Security app's Settings.

Register Your Fingerprint

After setting an access code, the eufy Security app will prompt you to register your fingerprint. The fingerprint light will breathe white.

1. Register your fingerprint by placing it on the touch screen. If valid, it will be recorded. You must register your fingerprint 8 times. Each successful registration lights up the corresponding number (1-8).
2. If the app fails to record your fingerprint, the light will breathe red. Move your finger slightly and try again.
3. Once successfully registered, the fingerprint light will turn off.

Note:

• People over 70 and children under 5 are recommended to use keypads for access codes.
• Use your thumb, index, or middle finger for fingerprint registration.
• You can skip fingerprint registration during initialization and do it later.

Other Settings

The Smart Lock Touch & Wi-Fi offers several configurable features via the eufy Security app:

• Add up to 100 users
• Set language (English)
• Synchronize lock time with your phone
• Customize voice volume
• Customize automatic door-locking time (up to 3 minutes)
• Enable/disable sound effects
• Automatically record door opening/locking logs
• Failsafe mode: After 5 consecutive failed fingerprint attempts, the scanner is disabled (access code still works). After 5 consecutive failed access code attempts, neither the code nor the scanner works.
• Check device information

OTA Update (Optional)

If your device requires an OTA update, the app will prompt you. Follow the on-screen instructions. If no update is needed, the app will skip this process.

Note:

• OTA updates are not allowed when battery power is below 25%.
• After a successful OTA update, wait 1 minute and reboot the Smart Lock Touch & Wi-Fi.
