2. Align the new keycap with the switch stem and press down firmly until it is securely seated.

Troubleshooting

• Keyboard not responding (Wired): Ensure the USB Type-C cable is securely connected to both the keyboard and your computer. Try a different USB port or cable. Confirm wired mode is active (Fn+5).
