Get your Keychron Q5 Max up and running with QMK/VIA. Step-by-step instructions for pairing, key mapping, and avoiding common setup mistakes.

Quick answer

Pair your Q5 Max via Bluetooth or USB, then use the QMK or VIA software to remap keys and manage layers. The Fully Assembled version arrives ready to go, but you'll still need to install the firmware tool and configure your layout.

What you need before you start

Your Q5 Max ships with the keyboard PCB, case, PC plate, keycaps (including Mac and Windows sets), and switches. The ISO layout options include German, UK, Nordic, and Swiss — choose the correct one during setup to match your printed keycaps.

Because the Q5 Max is a wireless custom keyboard, you have two connection paths: USB-C for a wired low-latency link or Bluetooth for a cable-free desk. QMK and VIA each handle wireless differently, so pick the one that fits your operating system and workflow.

Step-by-step setup

1. Charge and power on: Connect the USB-C cable to a power source and charge the battery fully. Press the power switch on the back of the keyboard to turn it on. The LED indicator should blink. A low battery can cause intermittent disconnects during pairing. Charge for at least 2 hours before the first use.
2. Choose your connection method: For a wired connection, plug the USB-C cable into your computer and the keyboard will be recognized as a standard HID device. For Bluetooth, put the keyboard in pairing mode (hold the Bluetooth button for 3 seconds) and select it from your computer's Bluetooth settings. Bluetooth pairing may require a driver or firmware update on some systems. If the keyboard doesn't appear, check that no other wireless keyboard is connected.
3. Install QMK or VIA firmware: Download the latest QMK firmware from the Keychron GitHub or VIA software from the official website. Run the installer and follow the on-screen prompts to flash the firmware to the keyboard. This enables remapping and layer switching. Do not disconnect the keyboard during firmware flashing. A power loss can brick the PCB and require a recovery procedure.
4. Configure your layout and keycaps: In the QMK Configurator or VIA app, select your ISO layout (German, UK, Nordic, or Swiss) and assign the correct keycap set. The included Mac and Windows keycaps are physically different; match them to your OS for accurate legends. If you swap keycaps later, you must update the software layout to match, or the printed legends won't align with the actual key functions.
5. Remap keys and test layers: Use the software to remap any key to a different function, create macros, or set up multiple layers (e.g., gaming, typing, media). Save the profile to the keyboard's onboard memory. Test each layer by pressing the layer-switch key and verifying the LED color change. Always save a backup of your default layout before making changes. A misconfigured layer can be reset by reflashing the firmware.
