4. Setting Your Combination
Your Vivi Bike Lock comes with a factory preset combination, usually 00000. Follow these steps to set your personal combination:
- Open the Lock: Align the factory preset combination (e.g., 00000) with the indicator marks on the lock head and pull the lock head out from the cable end.
- Locate the Reset Mechanism: With the lock open, locate the reset dial or button. This is typically a small knob or lever on the side or end of the lock head.
- Engage Reset Mode: Rotate the "SET" dial clockwise 90 degrees (or as indicated by an arrow) until it clicks into place, or push the reset button firmly.
- Set New Combination: While in reset mode, rotate the number wheels to your desired 5-digit combination. Choose a memorable combination.
- Disengage Reset Mode: Rotate the "SET" dial back counter-clockwise 90 degrees (or as indicated) to its original position. This will lock in your new combination.
- Test New Combination: Scramble the numbers on the wheels. Then, align your new combination and attempt to open the lock to verify it works correctly.

Important: Remember your new combination. There is no master key to open the lock if you forget it.
5. Operating the Lock
Using your Vivi Bike Lock is straightforward:
- To Open: Align your personal 5-digit combination with the indicator marks on the lock head. Pull the lock head away from the cable end.
- To Lock: Wrap the cable around your bicycle frame and a secure, immovable object (e.g., a bike rack, lamppost). Insert the cable end into the lock head until it clicks securely into place.
- Secure the Combination: Once locked, scramble the numbers on the combination wheels to prevent unauthorized access.
