How do you fix a space bar on one side?

To fix a space bar that is sticking or not functioning properly on one side, first, carefully remove the keycap using a flat tool or your fingers. Inspect the mechanism underneath for any debris or misalignment; clean it if necessary. If the stabilizer clips are damaged or not seated properly, gently reposition or replace them. Finally, reattach the keycap, ensuring it sits evenly and functions smoothly.
