How to Disassemble the Keychron M6 Mouse
If everything works fine with your mouse, it is not recommended to try this at home as it can risk injuries and damage caused by disassembling. Disassembling the M6 will void its returns and warranty.
Step 1: Begin by peeling off the two pieces of film on the back of the mouse. Then, unscrew the four screws. Gently lift the top case and pull back to open both the top and bottom cases. Note that there is a ribbon cable connecting them, so be careful not to tear it apart.
Step 2: Proceed to disconnect the two cables (from the top case to PCB and from the battery to PCB). Afterward, unscrew the three screws on the PCB.
There is a small buckle where the ribbon cable connected, push the small black buckle up to release the ribbon.
Step 3: Release the wheel and disconnect the ribbon cable from the wheel to the PCB. Your disassembly is now complete.
