Replacement Keys
These plastic keys will replace broken ones on your keyboard. There are several different types of keys used on the Roland keyboards, so you will need to make sure you order the correct style (click on the link for your keyboard below). With the exception of the Top C note on the 61-note keyboards, all keys from octave to octave are identical, and all black keys within a given style are identical. In other words, a B note in the lowest octave uses the same key as a B note in any other octave. But the highest C note is different from the other C notes (see illustration below).

If you do not know the note names, on the 61-note keyboard shown below, the white keys from the bottom (left side) up are: C, D, E, F, G, A, B, and then the sequence repeats.

Parts
We stock both new and used parts; the individual item descriptions will specify whether a part is NEW or USED. All used electronic parts are tested and guaranteed working. This listing reflects our current inventory and is updated daily, so if a part is shown with a "Buy" button, we should have it in stock.

If a part is shown as Out of Stock, then we do not have it, and in most cases, we don't know when or even if we might have it again. Your best bet is to simply check back on our site occasionally. If a part is not listed on our site, then we do not carry that part. We can no longer research or special order parts that are not listed here, and we just don't have time to answer questions about parts that we don't carry.

We want to help you get the parts you need, but please do not ask us to help diagnose problems with your equipment. We simply don't have the resources to do this, and it is just not practical to diagnose repair issues without being able to test the equipment in person.
