Easy Assemble

We designed every component to be able to assemble easily so you can customize and adjust each component with ease to create your ultimate typing experience.

Component of Keychron Q3 Pro QMK/VIA Wireless Custom Mechanical Keyboard ISO Layout Collection

Double-Gasket Design

The Double Gasket Design is a new innovative structure in the industry. In addition to the gaskets on the plates, we added silicone pads between the top and bottom cases to significantly reduce the sound resonance between the metals and reduce the noise of the impacted metals.

Experience the next level of key sounds and comfort with our gasket mount design together with a flexible PC (Polycarbonate) plate. This design combination allows the keyboard to maintain the flexibility of the gasket structure and improves the overall typing sound.

An Epic Core Inside The Keyboard

A powerful ultra-low-power ARM Cortex-M4 32-bit STM32L432 chip (MCU) equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz right out of the box on type-c wired mode (90 Hz on wireless mode), which makes the latency hardly noticeable even in competitive games.

Suitable for All Devices

Built with the Mac users’experience in mind while still retaining compatibility for Windows devices, the Q3 Pro comes with a system toggle and an additional set of customized keycaps for both Windows and macOS systems. You can now save two different layouts on the keyboard, one for each system.

Custom Macro Keys

The Q3 Pro Special Edition has four macro keys on the left side. They can be custom and assigned to different actions via the VIA software, simplifying your input and reducing your workload.

Custom Macro Keys

Programmable Knob

Designed to enhance your creative workflow, the aluminum rotary encoder allows you easily customize the knob to your desired key or macro commands like zooming in/out, adjusting screen brightness, brush size, volume, selecting video clips or photos, or backlight hue.

Endless possibilities for a fluid workflow thanks to its ability to remap any key, and create macro commands, shortcuts, or key combinations through the QMK/VIA.

Check out the video above demonstrating how to remap the Home key to an Eject key with the VIA software to create a shortcut to put your Mac to sleep (Command-Option-Eject).

Get the Q3 Pro keymap working on VIA

Since the VIA code for the Q3 Pro is still awaiting approval from Github, it is not yet automatically recognized. Please download the appropriate keymap JSON file below, open VIA, turn on "Show Design tab" on "Settings" tab, and drag the JSON file into the “Design” tab on VIA to get the Q3 Pro keymap working on VIA.


Every detail matters for a personalized typing experience, that’s why we give you the power. You can hot-swap every switch on the Q3 Pro with almost all of the 3pin and 5pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering required. You can customize your own typing experience in seconds.

*The four macro keys (M1~M4) on the Q3 Pro SE are not hot-swappable.

South-Facing RGB

Comes with 22 types of RGB backlight settings. You can further fine-tune the RGB hue, saturation, brightness, effect speed, and different modes, or even remap these keys with QMK/VIA.

OSA ABS Backlight Shine-Through Keycaps

To further leverage your typing experience, the Q3 Pro ISO version comes with our unique OSA profile (OEM profile with spherical angle) and ABS backlight shine-through keycaps that aim to provide a more comfortable fingertip feel and a fantastic backlight shine-through effect.

Keychron K Pro Mechanical Switch

By optimizing the switch mold, the Q3 Pro switch wobbles less than the standard mechanical switch and feels smoother on each hit. Plus, the factory pre-lubed K Pro switches will ensure the best fingertip smoothness. Not to mention the banana switch provides an early tactile bump at the top with a uniquely smooth experience like those Panda switches on the market.

Keychron K Pro Switch Features
PCB Stabilizers

PCB Stabilizers

No detail is too insignificant when it comes to your fingertip feel. We’ve integrated the PCB-mounted screw-in stabilizers for a smoother typing experience with less wobbliness on the big keys such as the space bar, shift, enter, and delete keys. You can even customize your favorite stabilizers on your own.
