Sticky piano keys are one of the most common problems found in upright and grand pianos in Singapore. High humidity, moisture, mould, worn balance pins, or faulty piano heaters can all cause keys to move slowly or become stuck.

Ignoring sticky keys can affect your playing experience and may eventually damage the piano action. A professional piano technician can identify the exact cause, clean the action, adjust the keyboard, replace damaged parts if necessary, and restore smooth key movement.
