Troubleshooting

Connectivity Issues

• Keyboard not connecting via 2.4 GHz: Ensure the 2.4 GHz receiver is securely plugged into a USB port and the keyboard is switched to 2.4 GHz mode. Try a different USB port.
• Bluetooth pairing failure: Ensure the keyboard is in Bluetooth pairing mode (Fn + 1/2/3 held for 4 seconds). Remove any previous "Keychron B6 Pro" entries from your device's Bluetooth list and try pairing again. Ensure your device's Bluetooth is enabled.
• Wired connection not working: Verify the Type-C cable is properly connected to both the keyboard and your device. Ensure the keyboard is switched to wired mode. Try a different Type-C cable or USB port.

Key Input Problems

• Keys not registering or registering multiple times: This can sometimes be caused by dust or debris under the keycap. Try cleaning the affected key with compressed air. If the issue persists, ensure the keyboard's firmware is up to date via the Keychron Launcher.
• Incorrect key output (e.g., 'Q' types 'qwe'): Check the operating system switch on the keyboard to ensure it matches your current OS. If using custom keymaps, verify the settings in the Keychron Launcher.
• Delay in key response: In wireless modes, ensure there are no significant obstructions between the keyboard and the receiver/device. For Bluetooth, minimize interference from other wireless devices.

Physical Issues

• Keyboard not sitting flat: Due to its ultra-slim design, minor warping can occur. Ensure the keyboard is placed on a flat, stable surface. If the issue is significant, contact customer support.
