Introduction

A jammed or weighted key may disrupt or ruin your piano playing. This guide demonstrates how to fix a stuck or sticky key on your Williams Allegro III digital keyboard.

It is common for a key on a digital piano to get stuck or sound softer. Electronic keyboard keys may stick or become unresponsive due to dust or grime buildup underneath, or if a key becomes misaligned. In some cases, the key might even become bent.

Before you begin this repair, unplug the keyboard from the power source and make sure the keyboard is off.

It is best to avoid drinking or eating near your keyboard as crumbs and liquids could contribute to the problem.

    • Flip the keyboard over so the bottom is facing up.

    • Make sure to unplug the keyboard as this is a necessary step to follow this guide safely.

    • Use a Phillips #0 screwdriver to remove eleven long screws from the back case.

    • Use a Phillips #0 screwdriver to remove 27 short screws from the back of the keyboard.

    • There should be a total of 38 screws:11 long screws (indicated in red) and 27 short screws (indicated in orange).

    • Unclip each key that is stuck or needs repair and pull it off the board carefully.

    • Check that the hammer (gray piece) and clip (blue piece) are in line with each other.

    • Every hammer should have a corresponding small, black rubber pad on top.

    • If the rubber pad is loose, misaligned, or falling off, it is important to superglue it back into place similar to how the other key pads look.

    • Clip the key back onto the keyboard by pressing down on each end, one at a time.

    • This method will ensure that you can hear and feel each key end clip into place correctly.

  8. NbbWUNBXiU5juvHo

    • Plug the keyboard back into the electrical source and test the sound of the key you are fixing.

    • If sound has not improved or the key remains stuck, then repeat steps 3-7 to ensure the key is properly cleaned and correctly attached.

Conclusion

To reassemble your device, follow steps 7 and 9. This guide can be used for multiple key repairs as long as you repeat the necessary steps for each stuck key.
