4. Operating Instructions

4.1 QMK and VIA Customization

The Keychron Q3 supports QMK and VIA firmware, allowing for extensive customization of keymaps, macros, and lighting effects. VIA is a graphical user interface that simplifies the process of remapping keys and creating macros without needing to write code. Download the VIA software from the official Keychron website or the VIA GitHub repository.

4.2 Hot-Swappable Switches

The Keychron Q3 features hot-swappable sockets, allowing you to change switches without soldering. It comes pre-installed with Gateron G Pro Brown switches. The PCB is compatible with most MX style 3-pin and 5-pin mechanical switches (e.g., Gateron, Cherry, Kailh). Use the provided switch puller to carefully remove and install switches.

5. Maintenance

5.1 Cleaning

To clean your keyboard, disconnect it from the computer. Use a soft brush or compressed air to remove dust and debris from between the keycaps. For stubborn dirt, gently wipe the keycaps and case with a slightly damp, lint-free cloth. Avoid using harsh chemicals or excessive moisture.

5.2 Switch and Keycap Replacement

The hot-swappable design allows for easy replacement of switches and keycaps. Use the provided keycap puller to remove keycaps by gently pulling straight up. Use the switch puller to remove switches by gripping the top and bottom clips and pulling upwards. When installing, align the switch pins with the PCB sockets and press down firmly until it clicks into place. Ensure the pins are not bent.

5.3 Stabilizers

The Keychron Q3 uses screw-in PCB stabilizers for enhanced stability on larger keys (Space Bar, Shift, Enter, Delete). These can be lubricated or replaced if needed for a smoother typing experience. Refer to online guides for proper lubrication techniques if you wish to perform this maintenance.
