To use VIA:
- Download the VIA software from the official Keychron website.
- Connect the K8 Pro to your device using the USB-C cable. Key remapping is performed in wired mode.
- Launch the VIA software. The keyboard should be automatically detected.
- Drag and drop desired keys or macro commands to remap any key. Changes are saved to the keyboard's firmware and will function in both wired and wireless modes.
5.2 Hot-swappable Switches
The K8 Pro features hot-swappable switch sockets, allowing you to change mechanical switches without soldering. It is compatible with most 3-pin and 5-pin MX mechanical switches.


To replace switches:
- Use the provided keycap puller to carefully remove the desired keycap.
- Use the provided switch puller to gently grasp and pull the switch upwards from its socket.
- Align the pins of the new switch with the holes on the PCB and press down firmly until it clicks into place. Ensure pins are not bent.
- Reattach the keycap.
5.3 Double-Shot PBT Keycaps
The K8 Pro comes with durable double-shot PBT keycaps, designed for enhanced feel and oil resistance.

6. Maintenance
6.1 Cleaning
To clean the keyboard, power it off and disconnect it from any devices. Use a soft, dry cloth to wipe the keycaps and chassis. For deeper cleaning, keycaps can be removed using the provided keycap puller and cleaned with a mild solution. Ensure all parts are completely dry before reassembly and use.
6.2 Battery Care
The K8 Pro is equipped with a 4000 mAh lithium-ion battery. To prolong battery life, avoid fully discharging the keyboard frequently and store it in a cool, dry place when not in use for extended periods.
7. Troubleshooting
7.1 Connectivity Issues
- Bluetooth not connecting: Ensure the keyboard is in Bluetooth mode and discoverable. Remove previous pairings from your device and try pairing again. Ensure the keyboard battery is charged.
- Wired connection not working: Verify the USB-C cable is securely connected to both the keyboard and the computer. Ensure the keyboard is switched to 'Cable' mode. Try a different USB port or cable.
7.2 Key Programming Issues (VIA)
- VIA software not detecting keyboard: Ensure the keyboard is connected via USB-C cable and the OS switch is set correctly. Restart the VIA software and/or your computer.
- Remapped keys not working: Confirm that the changes were successfully saved in VIA. Remember that key remapping must be done in wired mode.
7.3 Backlight Visibility
The K8 Pro features south-facing LEDs. While this design offers compatibility with a wider range of custom keycaps, it may result in less illumination of keycap legends compared to keyboards with north-facing LEDs, especially in low-light conditions. This is a design characteristic and not a defect.
7.4 Physical Fit/Feel
Some users may experience the keyboard's frame being slightly higher than the keycaps, potentially affecting the feel of certain keys like the spacebar. This is part of the keyboard's design and construction.
