It really depends on what is wrong. You might have: - Dirt in the key. Not bad, it should clean up.
- Something spilled in the keyboard. Okay, but tougher to clean since you don't know what it is.
- A just plain worn out key contact. Ugly. Major surgery, follow the previous link and good luck.
If it is just a dirty key, in the order of effectiveness: - Ultrasonic cleaning of the entire unit which cleans inside the keyboard.
- Placing a few drops of isopropyl alcohol between the key and the surround and pressing the key a few times. Works many times for not-so-bad units.
Any cleaning should be done with batteries out and allowed to dry throughly before reinstalling. Leaving batteries in a wet Pioneer will result in keyboard destruction via electrolysis in about 24 hours.
