3. Setup: Setting Your Combination

Your Lydsto Bike Chain Lock comes with a default combination of 00000. Follow these steps to set your personalized 5-digit combination:

1. Step 1: Open the Lock with Default Combination. Align all five dials to the default combination "00000". Ensure all numbers are aligned with the marking arrows. The lock will then open.
2. Step 2: Rotate the Reset Knob. With the lock open, locate the "RESET" knob (usually a small black knob at the end of the combination mechanism). Rotate this knob 90 degrees to the right (clockwise).
3. Step 3: Set Your New Combination. While the reset knob is in the rotated position, set your desired 5-digit combination by turning each dial. Make sure each number is precisely aligned with the marking arrow.
4. Step 4: Return the Reset Knob. Once your new combination is set, rotate the "RESET" knob 90 degrees back to its original position (counter-clockwise).
5. Step 5: Scramble the Dials. Scramble the dials to lock the mechanism. Your new combination is now set.

Friendly Reminder: Take a photo of your new combination or write it down and store it in a safe place. This will help you if you forget the code.

5. Maintenance

• Cleaning: Wipe the lock and chain with a damp cloth to remove dirt and grime. Avoid harsh chemicals that may damage the protective cover or mechanism.
• Lubrication: Periodically apply a small amount of lubricant (e.g., silicone spray) to the combination dials and the locking mechanism to ensure smooth operation.
• Storage: Store the lock in a dry place when not in use to prevent rust and prolong its lifespan.
• Inspection: Regularly inspect the chain and locking mechanism for any signs of wear, damage, or corrosion. If significant damage is observed, consider replacing the lock.

6. Troubleshooting

6.1. Dials are Stiff or Hard to Turn

• Solution: Apply a small amount of lubricant (e.g., graphite powder or silicone spray) to the dials and rotate them back and forth to distribute the lubricant. Ensure no dirt or debris is obstructing the dials.

6.2. Lock Does Not Open with Correct Combination

• Solution: Double-check that each number is perfectly aligned with the marking arrows. Sometimes, a slight misalignment can prevent the lock from opening. Ensure you are using the correct, most recently set combination.

6.3. Forgot Combination

• Solution: Unfortunately, if you have forgotten your combination and did not record it, there is no master key or backdoor to open the lock. The lock is designed for high security, and without the correct combination, it cannot be opened non-destructively. You may need to use bolt cutters or similar tools to remove the lock, which will render it unusable.
