Introduction

Follow this guide to replace the keyboard PCB in a Keychron K10 Max Wireless mechanical keyboard.

The keyboard PCB is the main circuit board that connects the key switches and allows the keyboard to register inputs. It also supports other functions such as lighting and internal connections. A PCB replacement may be needed if several keys stop responding, keys type the wrong characters, sections of the backlight stop working, or the board shows signs of damage such as corrosion, cracks, burn marks, or damaged connectors.

Before replacing the PCB, rule out easier fixes such as reseating or replacing key switches, checking the USB-C cable, inspecting the battery, and making sure all internal ribbon cables are fully connected.

This repair requires opening the keyboard and handling fragile electronic parts, so power off the keyboard and disconnect all cables before starting.

What you need

Step 1 Keycap

Lay the keyboard face down on the workspace.
Use a 2.5 mm hex screwdriver to remove the eight 4.5 mm screws from the back case.
Carefully separate the front frame from the keyboard and set it aside.
There is a clear shield that sits right above the arrow keys. This shield is to diffuse the LEDs from the keyboard, and it can fall out easily. Just remember to put it back if it does when reassembly.

Slide the keycap puller over the keycap until it grips underneath.

Place the switch puller around the two small tabs on the front and back of the switch.
Squeeze the switch puller to release the tabs, then pull straight upward to remove the switch.
The photos show red mechanical switches, but your keyboard may have a different switch color. The removal process is the same for this style of hot-swappable mechanical switch.

The replacement switch is oriented to fit only one way.
Align the copper pins on the bottom of the switch with the socket.
Make sure the copper pins are aligned before pressing the switch into place. Installing the switch in the wrong orientation can bend or break the pins.
Press the switch straight down until it clicks into place.
The switch should sit flush with the surrounding switches and the keyboard frame.
