It can be exasperating – if not downright impossible- to practice or perform on your digital piano if it has a key or keys that don’t work right. Although this is pretty frustrating, it doesn’t necessarily mean you have to run out and buy a brand-new digital piano! Instead, there are a few things you can try to fix the problem.
In this article, we will look at a few ways to fix keys that don’t work on a digital piano or keyboard. We’ll look at how to fix a loose cable bus, clean inside your digital piano, and fix an individual key. First, though, let’s talk about the warranty on your digital piano.
If your digital piano is under warranty, you’ll want to have it serviced by an approved professional. This way, you don’t void the warranty if the problem is something you can’t fix.
Your local music store should be able to help you find a repair person that works with your digital piano company. If your digital piano is older, out of warranty, or there isn’t a way to get the digital piano repaired, there are a few things you can check yourself to fix the problem.
If you are going to attempt to fix your digital piano yourself, keep in mind that these instructions will give you a basic idea of how to do so. However, every digital piano or keyboard model is different, and you may need to consult your owner’s manual or call the company for more specific information.
For most of these repairs, you’re only going to need a few screwdrivers, some cleaning supplies such as a dry cloth, a small vacuum, cotton swabs, and possibly, new keys. You can consult your owner’s manual for the specific location of the screws you need to loosen to access the inside of your digital piano.
A common issue with digital pianos and keyboards is that a cable bus can come loose from playing hard on the keys, moving the piano around, or even just from the vibrations created by the keyboard. As a result, you’ll notice that some or even all keys aren’t working. If you know it isn’t a specific key that is broken, this is probably the first thing you need to check.

Over time, dirt and dust can make their way into your digital piano. If too much dirt gets in between the sensitive sensors, it can keep the digital piano from playing or working correctly. However, cleaning it up is a pretty easy fix.
If the problem isn’t fixed, there may be other issues to consider.

Another common problem is when something falls between the keys on your digital piano. A coin, gum wrapper, or other small thin items can slide in between and get stuck. Follow the process you would for cleaning your digital piano keys (it’s a great idea to clean it while you’ve got the digital piano opened up anyway). And look for anything that might be stuck in the keys. Gentle remove it and put the digital piano back together.
If one of your keys is broken, cracked, or chipped, you’re going to need to replace it. Use masking tape to mark which key is broken or not working correctly.
When in doubt, call a professional repair person. They can quickly and easily fix or repair your digital piano for you.
On the other hand, if you’re doing it yourself, never risk your safety when attempting a digital piano repair. This means you absolutely must unplug the digital piano before fixing it. You could easily get shocked if you try to repair your digital piano while it is still plugged in.
