KAK Q3 Smart Fingerprint Cylinder Door Lock

1. Introduction

This is a general-purpose smart fingerprint cylinder lock, suitable for indoor use in homes, offices, apartments, and other locations. It integrates multiple unlocking methods including fingerprint recognition, password, and app control, providing secure, convenient, and efficient security for your doors.

The KAK Q3 lock utilizes high-precision fingerprint recognition technology for fast and accurate access. It features a durable lock body and stable electronic components, making it compatible with most indoor wooden and metal doors for daily security needs.

2. Safety Information & Warnings

• Keep the fingerprint lock, emergency key (if applicable), and small accessories (screws, expansion pipes, batteries) away from infants and young children to prevent choking, pinching, electric shock, or scratching hazards.
• Install the lock on a firm, flat, and clean door surface. Do not install on fragile, loose, or uneven doors to prevent the lock from loosening or falling off.
• Do not disassemble, repair, or modify the lock yourself. This will void the warranty and may cause electric shock, fire, lock failure, or security risks.
• Use only the specified type and model of batteries. Do not mix old and new batteries or different types of batteries. Remove batteries if the lock will not be used for a long time to prevent battery leakage and damage.
• Keep the lock away from water, moisture, corrosive chemicals, high temperatures, and direct sunlight, which can cause short circuits, rust, deformation, or functional failure.
• During installation, avoid drilling into wires, pipes, or other hidden objects inside the door. Use only the matching tools and screws, and do not use excessive force.
• Do not disclose your password or share your fingerprint with unauthorized personnel to avoid security risks. Regularly update your password.
• If the lock shows abnormal conditions (e.g., overheating, unusual noise, failure to recognize fingerprints), stop using it immediately, remove the batteries, and contact customer service.

3. Setup & Installation

3.1 Pre-installation Check

• Ensure your door thickness is between 35-45mm.
• Measure your existing lock core height:
  • If the lock core height is less than 30 mm, choose the Small size (S).
  • If the lock core height is 30 mm or above, choose the Large size (L).

3.2 Installation Steps

1. Clean and dry the door surface to ensure it is flat and dust-free. Confirm the door thickness matches the lock's requirements.
2. Mark the installation position according to the lock's size and drill holes as required. Refer to the provided installation drawing for precise measurements.
3. Install the new smart lock cylinder into the door.
4. Install the control panel and battery. Test whether the lock powers on normally.
5. After installation, test all unlocking methods (fingerprint, password, app) to ensure smooth operation. Adjust the lock bolt if necessary.

4. Operating Instructions

4.1 Unlocking Methods

• Fingerprint Unlock: Place your registered finger on the fingerprint sensor. The lock will unlock if the fingerprint is recognized.
• Passcode Unlock: Enter your registered passcode on the dial and press 'OK'.
• Temporary Password: Generate temporary passwords via the Tuya/Smart Life app for guest access.
• App Unlock: Use the Tuya/Smart Life app on your smartphone to unlock the door via Bluetooth.

4.2 Virtual Password Feature

To enhance security, you can enter random digits before and after your actual passcode. This prevents others from guessing your code by observing your finger movements.

4.3 Emergency Unlocking Methods

• Type-C Emergency Power: If the batteries are completely drained, you can connect a Type-C power bank to the emergency power port on the lock to temporarily power it and unlock the door.
• Low Battery Indicator: The lock will indicate a low battery status (e.g., a red light or specific sound) when power is running low, prompting you to replace the batteries.

4.4 App Setup (Tuya/Smart Life)

Download the Tuya Smart or Smart Life app from your smartphone's app store. Follow the in-app instructions to add your KAK Q3 smart lock, register fingerprints, set passcodes, and manage users. Detailed instructions for app features are typically provided within the application itself.

5. Maintenance

• Cleaning: Regularly wipe the fingerprint sensor and lock body with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Battery Replacement: Replace batteries promptly when the low battery indicator appears. Use only the specified battery type.
• Environmental Care: Keep the lock dry and protect it from extreme temperatures and direct sunlight to ensure optimal performance and longevity.

6. Troubleshooting

• Fingerprint not recognized: Clean the fingerprint recognition area and your finger (ensure both are dry and clean). If the issue persists, try re-registering your fingerprint through the app.
• Lock not powered on: Check if the batteries are installed correctly. If so, replace them with new batteries.
• Lock cannot be unlocked: Verify that the password or fingerprint entered is correct. If you have an emergency key (not included with this model), use it. If the problem persists, contact customer service.
• Lock is stuck: Do not force the lock. Check for any foreign matter blocking the lock bolt and clean it immediately.
