How to Fix Piano Keys That Don’t Work

If you have a piano that has some keys that don’t work, it can be frustrating. You might not know where to start with fixing the problem or even if the problem is fixable at all! This article will give you an overview of what’s involved in getting those missing notes back and how to make your own adjustments as needed. There might be various aspects related to this issue. For this reason, I will be discussing some solutions on how to fix piano keys that don’t work with all associated issues.

How to Fix Piano Keys That Don't Work

Reasons Behind Piano Keys Not Working

Particles that have fallen from the air can be a problem for pianos, especially newer ones. The best way to fix this is to clean the keys with a damp cloth or open up the piano and remove any particles that may be caught inside.

Faulty wiring:

If some of the notes on your piano sound wrong, it might be because a wire is loose. You’ll need to open up the piano and check all the wires to make sure they’re tight. If that doesn’t work, you’ll have to call an expert.

Damaged hammers:

If the hammer on one key is broken, it might still activate other keys nearby, causing them not to work properly. You will need to take the piano apart again and replace the hammer before continuing playing.

Faulty speaker:

If one of your speakers is not working, then you might have a faulty wire or loose connection that needs to be fixed immediately! If your speaker is emitting a crackling sound, then you might have a faulty driver that needs to be replaced.

Mechanical issues: Your wires could get stuck on something in the back compartment (we don’t recommend opening up this area yourself), causing them to move awkwardly when they’re supposed to make a sound. This will eventually cause all of your keys not to work properly and should be taken care of by an expert pianist as soon as possible! Damaged wires: This is a problem that needs to be fixed by a piano technician or shop as soon as possible. Although it’s not a big deal to have your keys slightly off, if the wires are sticking out, you’ll likely end up with more problems in the future.

Steps of How to Fix Piano Keys That Don’t Work

Measure the height of the hammers. They should be at least one centimeter (0.39 inches) of the strings while not pressing any keys, but this all depends on your model. If they’re too high or low, adjust them accordingly using a hammer and punch until you hear a click sound when striking each key with your finger to find the right height. This is usually done from the inside by removing screws that hold the lid in place; some pianos have instructions for doing this online if it’s difficult to determine where these are located on yours without damaging anything else.

Removing Screws That Hold the Lid in Place

If there’s still no noise coming out of certain keys after adjusting their heights as well as releasing up every possible obstruction blocking those keys, the keys may be because their corresponding hammers are not holding them up. The solution for this is to use a small screwdriver or other implement and carefully push the key down to contact its hammer.

Sometimes, keys will stick due to deposits of dirt and grime on them, preventing them from resonating properly. If you can’t clean off what’s causing these issues by wiping away any built-up debris, try using rubbing alcohol instead – make sure that none gets into the piano as well!

If your hands are still dirty after doing all of this, consider getting some gloves before proceeding further (e.g., dishwashing gloves). This should help keep everything cleaner while working inside there.

Warning: Disconnecting anything else could cause permanent damage!-If the key is bent too far out of shape, or if you can’t fix it through any other means, turn off the power to your piano and take apart one side of the case. This will expose all the parts necessary for fixing a broken damper (or hammer) that have come loose from its corresponding pedal.

You’ll need to locate and identify what part needs replacing before proceeding further – this may be as simple as removing four screws holding down either an individual screw or a small metal piece with two holes in it on each end. Ensure not to lose these pieces when reinstalling everything by placing them back into their original position before putting everything back together.

What to Do if the Hammer/ Damper of My Piano Gets Loose?

This is what you need to do when a damper or hammer becomes loose:

  1. Remove the two screws holding down either an individual screw or a small metal piece with two holes in it on each end (make sure not to lose these pieces!)
  2. Locate and identify which part needs replacing before proceeding further – this may be as simple as removing four screws holding down either an individual screw or a small metal piece with two holes in it on each end; make sure not to lose these pieces!
  3. Replace old parts, then reassemble everything back into place by first placing back all the tiny little pieces previously removed from your piano keyboard and put them right where they were originally located.
  4. Replace the four screws previously removed to make sure that everything is snug.

What to Do if the Keys of My Piano Gets Stuck? 

This is a common problem on pianos, and it can be fixed with the following steps.

Use a Screwdriver

Step One:

Use your hands to get into the piano’s lower parts to loosen all of its strings. This will allow you to release pressure between the stuck key and its corresponding string that causes it not to work properly. The goal here is really just so that there’s some space between them again – otherwise, they might continue rubbing against each other, which will only make more issues happen over time! You may need an assistant for this step if you don’t want to make any physical contact if something goes wrong.

Step Two:

Once you’re done with Step One, start loosening up the crossed-over hammers with your hands – the hammers that are under each key. You’ll need to remove them and then put them back on, but be careful with how you’re doing it because they might fall out of the piano and break!

Step Three:

Once Step Two is completed for every key in the keyboard (you may have to do this multiple times), go ahead and re-solder any broken wires or replace a damaged switchboard. If there’s no option like these available, don’t worry about fixing anything at all; make sure everything is as loose as possible before proceeding onto step four.

Step Four:

Take out pedals that are currently pressed down using something heavy like a book or a brick. You don’t want them to be pressed while you’re loosening the screws that are holding the keys in place. Otherwise, they may get knocked over and cause damage.

Expert Tip:

If your piano is more than 70 years old or not well-maintained, it might have corrosion on its metal parts, which causes many problems when trying to fix it. It’s best if this problem just gets fixed by replacing the entire mechanism with an electric keyboard because these keyboards don’t require any maintenance at all!

Replacing the Entire Mechanism

What to Do When My Piano Goes Out of Tune?

The first thing you should do is try to identify the problem. Usually, a piano will go out of tune due to humidity levels in your home or because someone has played it too much and bent keys. If you think an outside force caused the issue, then please contact a professional as soon as possible.

But if you’re sure that no one but yourself has played the instrument, some steps can be taken at home to fix this issue. First, make sure all four feet are raised off any surfaces they may have been resting on before removing any dust from under them using furniture polish (or compressed air).

This process might only need to be done every six months, depending on how often you play your piano. The next step is to identify which key or keys aren’t working and then clean the hammer on that key. This can be done with a soft cloth dipped in either water or rubbing alcohol.

The next step should only be taken if you notice some rust under the screws holding your piano’s action springs together, as this may indicate excessive humidity levels and could lead to other issues such as broken wires inside of your instrument.

To prevent future buildup from occurring again, it would also be wise for homeowners living in humid environments (or those who play their instrument often) to invest in an air conditioner or dehumidifier capable of removing at least 50 pints per day. The last thing to do when trying to fix a non-responsive note on a piano is to replace the string.

Precautions While Fixing Piano Keys

Wear a dust mask when sanding or scraping keys to avoid inhaling the particles. This will also help protect against any paint, stain, and varnish that may be on your lungs from old finishes.

Precautions While Fixing Piano Keys

If you have asthma or other respiratory ailments, take precautions before beginning repair work by first discussing this with your doctor.

There are many chemicals available for removing finish in new pianos; these should not be used if it is an older piano as they can cause damage to the wood and metal parts of the instrument.

Use eye protection such as goggles (or eyeglass lenses) whenever there’s a possibility of flying debris being thrown off during part repair work – even after all refinishing has been completed.


I hope that the processes I have mentioned here will surely be beneficial for fixing your piano keys that are not working. Thank you, and have a good day.
