Product Overview
Familiarize yourself with the components of your fingerprint padlock:
- Shackle: The metal loop that secures the lock.
- Zinc Alloy Lock Body: The main housing of the padlock.
- LED Indicator: A triple-colored light (red, blue, green) indicating status.
- Fingerprint Reader: The sensor for fingerprint recognition.
- Micro USB Charging Port: Located at the bottom, with a waterproof stopper.

Setup and Fingerprint Management
The padlock can store up to 10 unique fingerprints. The first two fingerprints registered are considered administrator (master) fingerprints, which are required to add or delete other user fingerprints.
1. Initial Charging
Before first use, fully charge the padlock using the provided Micro USB cable. The LED indicator will show charging status. A full charge takes approximately 1 hour and provides up to 6 months or 9000 unlocks of usage.

2. Registering the First Fingerprint (Administrator)
- Press and hold the fingerprint sensor until the blue LED light illuminates.
- Place your finger on the sensor. The blue light will flash.
- Lift and place your finger on the sensor repeatedly (approximately 10 times) from different angles to ensure comprehensive registration.
- Once successfully registered, the green LED light will illuminate, and the padlock will unlock. This fingerprint is now an administrator.
3. Registering Additional Fingerprints (Users)
- Press and hold the fingerprint sensor until the blue LED light illuminates.
- Place an already registered administrator finger on the sensor. The blue light will flash.
- Once verified, the blue light will remain solid. Now, place the new finger you wish to register on the sensor.
- Lift and place the new finger on the sensor repeatedly (approximately 10 times) from different angles.
- Upon successful registration, the green LED light will illuminate, and the padlock will unlock.

4. Deleting All Fingerprints
- Press and hold the fingerprint sensor for approximately 10 seconds until the red LED light flashes rapidly.
- Place an already registered administrator finger on the sensor.
- Hold the administrator finger on the sensor until the green LED light flashes, indicating all fingerprints have been deleted. The padlock will then unlock.
Operating Instructions
Unlocking the Padlock
- To unlock, simply place a registered finger on the fingerprint sensor.
- If the fingerprint is recognized, the green LED will light up, and the shackle will pop open.
- If the fingerprint is not recognized, the red LED will flash.

Locking the Padlock
- To lock, simply push the shackle down into the lock body until it clicks into place. The padlock will automatically lock.
Maintenance
Charging
- When the battery is low, the red LED indicator will flash quickly. Connect the padlock to a power source using the Micro USB cable to recharge.
- Ensure the waterproof stopper for the charging port is securely closed after charging to maintain IP67 water resistance.
Cleaning
- Wipe the padlock body and fingerprint sensor with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
Water Resistance
- The padlock is IP67 rated, meaning it is protected against dust ingress and immersion in water up to 1 meter for 30 minutes. However, prolonged exposure to water or harsh conditions should be avoided to maximize product lifespan.
Troubleshooting
- Padlock does not unlock: Ensure your finger is clean and dry. Try different angles or another registered finger. If the battery is low (red LED flashes), charge the padlock.
- Cannot register fingerprint: Ensure you are following the registration steps correctly, especially using an administrator finger to authorize new registrations. Make sure your finger is clean and dry.
- Padlock is unresponsive: The battery might be completely drained. Connect it to a power source for charging.
