Tested replacement built for repair benches, these blue side keys cover both the power button and the volume controls on the Xiaomi Mi CC9.
What You’re Getting
You receive one complete set of side keys in blue, matching the colour option listed for this part. Each unit is checked for good condition before it leaves our shelves, so you start with a working piece rather than a guess.
Why This Part Works
A worn or unresponsive side key can make your phone feel unreliable every time you lock the screen or adjust sound. This replacement brings back a firm, clean press. It fits the Mi CC9 layout and is designed to sit flush with the frame once installed.
Installation Notes
Work on a clean, well-lit surface and power the phone down first. Wear an ESD strap so static doesn’t damage the internal board. Keep flex cables gentle and never bend them past 90 degrees, or you risk a fault that’s harder to fix than the key itself. Testing the buttons before you reassemble the frame saves you from opening the phone twice. Professional fitting is the safest route if you’re unsure.
