6. Troubleshooting
If you encounter any issues with your Keychron K8 keyboard, please refer to the common troubleshooting steps below:
- One key does not work/register/input properly:
- Try to pop the keycap off and use compressed air to clear any dust or debris around the switch.
- If the issue persists, try to factory reset your keyboard by holding 'Fn + Z + J' for 4 seconds.
- Input Lag (Bluetooth Mode):
The Bluetooth latency is designed to be 30 milliseconds, but actual performance may vary. If you experience input lag:
- Try to factory reset your keyboard by holding 'Fn + Z + J' for 4 seconds.
- For wired mode, replug the data cable or use another data cable/port on your device.
- For Bluetooth mode, check for interference from nearby Bluetooth devices and try testing the connection with your smartphone.
- If you are a desktop user, ensure your motherboard’s Bluetooth antenna is installed. If your PC requires a Bluetooth adapter, please install one.
- Can't Type After Waking Up Mac:
This issue is caused by Apple's FileVault, which prevents third-party Bluetooth keyboards from unlocking the login screen.
Solutions:
- Turn off FileVault to enable normal login.
- Use a wired connection to enter your password.
Note: Keychron keyboards support FileVault login in wired mode only.
- How do I remap keys?
You can use third-party applications to remap keys (except the light effect key).
- For Mac users: Karabiner.
- For Windows users: SharpKeys.
