K4 Pro

Keychron K2 Pro Custom Mechanical Keyboard

Wireless and Wired

An excellent solution for multitasking. You can connect the K4 Pro with up to 3 devices wirelessly via its stable Broadcom Bluetooth 5.1 for seamless multitasking across your laptop, phone, and tablet. Switch among them swiftly, and it’s fully compatible with both Mac and Windows.

A reliable USB Type-C wired connection is also available when you need it.

Keychron K2 Pro Custom Mechanical Keyboard

Program with QMK & VIA.

QMK/VIA means endless possibilities for a fluid workflow. Simply connect the K4 Pro to your device with a cable, drag and drop your favorite keys or macro commands to remap any key you want on any system (macOS, Windows, or Linux). 

Check out the video above demonstrating how to remap the Light Effect key (located on the K4 Pro’s top right corner) to an Eject key with the VIA software, so you can get a shortcut to put your Mac to sleep (Command-Option-Eject), or even remap the fn key in a breeze. It’s never been so intuitive and flexible to personalize your own keymap.


An ultra-low-power ARM Cortex-M4 32-bit STM32L432 MCU which is powerful, and equipped with 128K Flash will provide more flexibility for developers.

Upgraded Typing Experience

The K4 Pro has been re-engineered and redesigned from the inside out to upgrade the typing experience. The added sound-absorbing foam, a thick silicone dampening bottom pad, and steel plate provide responsive feedback and a peaceful typing sound, while added weight will enhance the stability.

Suitable For All Devices

Offers a Mac layout while still being compatible with Windows, the K4 Pro is one of the few on the market that has the same multimedia and function key functions as Apple keyboards for Mac users, but with more tactile feedback.

You can even configure different keymaps for both Mac and Windows devices. While VIA software is compatible with macOS, Windows, and Linux. Includes keycaps for both macOS and Windows (3 keycaps for each) to allow you to switch between operating systems with ease.

Hot-swappable

Every detail matters, so we make the K4 Pro hot-swappable for your personalized typing experience. The hot-swappable sockets are mounted on the PCB, so you can hot-swap every switch on the K4 Pro with almost all of the 3pin and 5pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering. You can customize your own typing experience in seconds.

Keychron K2 Pro hot-swappable feature

The Barebone version (without switch and keycap) is also available at your choice.

Screw-In PCB Stabilizers

Even small part matters for 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 space bar, shift, enter, and backspace. The Keychron K4 Pro also supports third-party screw-in PCB stabilizers.

Pre-lubed Keychron K Pro Switch

By optimizing the switch mold, the K Pro switch wobbles less than a standard mechanical switch and feels smoother on each hit. Plus, the factory pre-lubed process on all the K Pro switches (exclude the clicky ones), no doubt this will ensure the best smoothness at your fingertips when typing.

Gateron K Pro Switch Features

OSA Profile Double-shot PBT Keycaps

To further fine-tune your typing experience, the K4 Pro comes with our unique OSA profile (OEM profile with spherical-angle) and double-shot PBT keycaps that aim to provide a more comfortable fingertip feel with excellent oil resistance for long-term use on the timeless tenkeyless layout.

Keychron K2 Pro OSA Profile Double-shot PBT keycaps

South-facing RGB Lights

The south-facing RGB is designed to better illuminate the keyboard backlight from the typist’s angle. The south-facing RGB is also free from interference when the user installs Cherry-profile alternative keycaps on their keyboard.

Comes with more than 22 types of RGB backlight settings (as well as a static white backlight option), and 14 types of backlight settings on the White Backlight version. You can further fine-tune the RGB hue, saturation, brightness, effect speed with ease.

Ergonomic Support

Three levels of adjustable typing angle (3º, 7º & 10º) and curved OSA-profile keycaps are all working together to provide long-lasting ergonomic support for your wrist.
