Korg CX3
Replacement Keys - Parts
Keyboard Service Center


There were two versions of the dual-manual BX-3 and single-manual CX-3 organs. The early models were introduced in 1979, and used analog circuitry. The organs were re-released in 2001, using digital circuitry. Early models had drawbard to the left of the keyboard, and the panel buttons had LEDs within them. Later models have the drawbars positioned over the keys, and the panel buttons have LEDs above them rather than as part of the button.

Note also that the later models used two different key types - some have a lip at the front of the key (Style K08L keys), others have a rounded waterfall-type edge (Style K08W keys).


Replacement Keys
The BX-3 and CX-3 models used several different key types during their production, so please make sure you match your keys to the photos here before purchasing. With the exception of the Top C note, all keys from octave to octave are identical, and all black keys are identical. If you do not know the note names, you can refer to the diagram below.



Parts
We stock both NEW and USED parts; all used electronic parts are tested and guaranteed working.

This listing reflects our current inventory and is updated in real time. If a part has no Buy button and shows Out of Stock, it is typically out of production and we don't know when or if we might have it again. By including out of stock parts in our listings, we hope to offer customers a more complete and useful resource.

We cannot diagnose repair issues by phone or email. For technical questions, we suggest posting on our Forums, where our techs - as well as other users - can offer help.
