The Yamaha Digital Piano series of keyboards is one of the most popular range of piano keyboards on the market, perhaps because of its long-standing history of being a reputable instrument manufacturer. The company first started making reed instruments in 1887. One major advantage to having an electronic keyboard instead of a stringed piano is that if the keys are ever sticky or broken, they're relatively easy to replace. If you're unsure about what you're doing, it's best to take your Yamaha keyboard to a local music shop or Yamaha dealer to fix the problem. In the meantime, consider these tips on repairing keys on your Yamaha piano keyboard.

    Broken Keys

  1. 1

    Determine the problem. Are the keys sticking on the Yamaha? Are they broken? Are they not playing sounds correctly? All of these things require different solutions.

  2. 2

    Remove the screws from both sides of the keyboard, then lift up the casing of the keyboard to enable you to get to the keys.

  3. 3

    Remove the key stop. This is situated on the front of the keyboard and runs the length of the instrument and prevents the keys from moving.

  4. 4

    Push down, then back on the key that you want to remove, with the key stop removed, to unhook it from the cut-out in the key frame. You may need to slide a thin object down the side of the key to separate it from the keyboard.

  5. 5

    Clean the key-bed with some gentle cleaners and clean rags. Get rid of the old lubrication and re-oil the key-bed with some piano oil. This should increase the movement range of the keys, making them play more clearly.

  6. 6

    Fix the key stop back onto the keyboard, then reassemble the rest of the keyboard in the order you removed it.

    Keys That Are Sticking

  1. 1

    Check the key that you just removed. If the rear hook on the bottom of the key looks broken or bent, this may indicate why the keyboard wasn't working properly. Unfortunately, a broken key isn't something that you can fix yourself. You'll need to get a new key.

  2. 2

    Insert the hook on the back of the replacement key into the notch on the key-bed.

  3. 3

    Make sure the hooks and notches are aligned, firmly press down on the key until you hear an audible click, which means the key is locked into place.
