Step-by-Step: How to Replace Your E-bike Battery Lock

Replacing the lock is easier than you think. Follow these four steps to get back on the road:

Step 1: Remove the Battery

Safely remove the battery from the bike frame. (Note: If your lock is jammed, please contact our [Technical Support] for specialized unlocking tips).

Step 2: Remove Screws on the Battery Upper Base

Locate the upper base where the battery connects. Use a precision screwdriver to unscrew the fasteners (refer to the red circled areas in the diagrams below).

Step 3: Detach and Swap the Lock Base

Unscrew the side bolts that secure the battery lock to the bike frame. Once loose, pull the entire battery base out.

• Detach the old lock mechanism.

• Snap the new Kingbull lock into the base, ensuring it aligns perfectly.

• Slide the assembled unit back into the frame.

Step 4: Secure Everything

Tighten the screws on both the upper base and the side of the bike. Double-check that the lock moves smoothly with your new key before inserting the battery.
