Installation

The TEKXDD Smart Lock is designed for easy installation and fits most standard doors with a thickness of 35-55mm. No drilling is typically required if replacing an existing deadbolt.

1. Prepare the Door:

   Ensure your door meets the specified thickness (35-55mm) and that the existing boreholes are compatible. The backset can be 60mm or 70mm, and the cross bore diameter should be 40-57mm.

2. Install the Latch Bolt:

   Insert the latch bolt into the door edge. Ensure the "UP" arrow on the latch bolt is pointing upwards. Secure it with screws.

3. Install the Exterior Handle:

   Pass the spindle and cable from the exterior handle through the latch bolt and the door. Ensure the handle is oriented correctly for your door's opening direction (left or right).

4. Install the Interior Handle:

   Connect the cable from the exterior handle to the interior handle. Align the interior handle with the spindle and secure it to the door using the provided mounting screws. Do not overtighten.

5. Install Batteries:

   Open the battery cover on the interior handle and insert 4 x AAA batteries (not included), ensuring correct polarity. Close the battery cover.

6. Test Operation:

   After installation, test the mechanical operation of the handle and latch. Ensure it moves smoothly without obstruction.

Setup

Follow these steps to set up your TEKXDD Smart Lock and connect it to the mobile application.

1. Download the App:

   Search for "Tuya Smart" or "Smart Life" in your smartphone's app store (iOS or Android) and download the application. Register an account if you don't have one.

2. Add Device:

   Open the app, enable Bluetooth on your phone, and tap "Add Device" or the "+" icon. The app should automatically discover the smart lock. If not, select "Security & Video Surveillance" > "Door Lock (Bluetooth)".

3. Pair the Lock:

   Follow the on-screen prompts to pair the lock. You may need to press a button on the lock or enter a default pairing code (refer to the specific app instructions).

4. Set Administrator Fingerprint/PIN:

   Once paired, the app will guide you to set up the administrator fingerprint and/or PIN code. This is crucial for managing other users and settings. Follow the app's instructions for multiple scans of your fingerprint for accuracy.

5. Add User Fingerprints/PINs:

   From the app, you can add additional user fingerprints, PIN codes, or temporary access codes for family members or guests. You can also generate one-time or time-sensitive codes.

6. Calibrate Lock Direction (if needed):

   Some locks require calibration of the opening direction within the app to ensure correct locking/unlocking behavior. Refer to the app's settings for this option.

Operating Instructions

Your TEKXDD Smart Lock offers multiple convenient ways to unlock your door:

• Fingerprint Unlock:

  Place your registered finger firmly on the fingerprint sensor. The lock will unlock with a confirmation sound/light if the fingerprint is recognized. The lock will automatically re-lock after a few seconds (default setting, adjustable in app).

• PIN Code Unlock:

  Enter your registered PIN code on the keypad, followed by the '#' key. The lock will unlock if the code is correct. Use the anti-peep function by entering random digits before or after your actual PIN to prevent others from guessing your code.

• Smartphone App Unlock:

  Open the "Tuya Smart" or "Smart Life" app on your smartphone. Ensure Bluetooth is enabled and you are within range of the lock. Tap the unlock icon in the app to unlock the door. You can also lock the door remotely via the app.

• Mechanical Key Unlock:

  In case of emergency, battery depletion, or electronic malfunction, insert the mechanical key into the keyhole and turn to unlock the door manually.

Maintenance

Proper maintenance ensures the longevity and reliable operation of your smart lock.

• Cleaning: Wipe the lock surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or liquid sprays directly on the lock.
