What You'll Learn
Replacing a stuck key
If you have a stuck key on your electric piano, you can try a few things before resorting to replacing the key. Firstly, determine the material of your keys. If you have ebony black and ivory white keys, clean them with extensive care. Modern digital pianos often have plastic keys, which can be cleaned with a damp cloth with a small amount of liquid soap. Gently rub the keys until they are completely clean. If your keys are still stuck, check the cleaning instructions specific to your piano brand, which can be found in the user manual.
If your keys are sticky, you may need to apply grease to make them work smoothly. To do this, disassemble the key and remove old grease with Isopropyl alcohol swabs. Then, apply new grease and reassemble the key.
If your keys are still stuck, you can try to release them by using a flathead screwdriver. Insert it gently between the stuck keys, prise them apart, and twist it slightly. If the keys are still stuck, you may need to remove the key entirely. To do this, remove the screws from the keyboard on both sides and lift up the casing of the board. Remove the key stop on the front of the board, push the key down, and unhook it from the frame.
If none of these solutions work, you may need to replace the key. If your piano is still under warranty, you can contact your dealer directly and seek professional help. If not, you can contact the manufacturer and request a replacement key. You can also find repairers online or buy new keys.

Removing and re-adding grease
If your electric piano keys are sticky or hard to press, the problem may be caused by old grease. To fix this, you will need to remove the old grease and apply new grease. Here is a step-by-step guide on how to do this:
Firstly, disassemble the keyboard by unscrewing all the screws from the back side and gently pulling out the keyboard. Keep the screws in a safe place, such as a bowl, as you will need them later for reassembly. Once the keyboard is open, you will be able to observe the key-bed and identify any issues.
Next, remove the affected white keys and use isopropyl alcohol swabs to clean away the old, sticky grease. Be careful not to damage the keys during this process. You may also use a quick spray of WD-40 or a dab of cooking oil to remove the old grease, but be sure to use a product that is suitable for lubricating pianos.
After the old grease has been removed, apply new grease to the keys. Ensure that you use the proper grease for lubricating pianos and apply it to the correct spots. The grease should be applied to the contact points between the keys and the weights or switches underneath.
Finally, reassemble the keyboard by screwing back in the screws you removed earlier and gently placing the keyboard back into the piano. Test the keys to ensure they are now functioning smoothly.
It is important to note that if your piano is still under warranty, it is best to contact the manufacturer to repair or replace the keys. Additionally, if you are unsure about any part of the process, it may be better to seek the help of a technician to avoid causing further damage to your instrument.

Replacing the rubber strip
If your digital piano's keys are malfunctioning, the rubber strip may need replacing. Digital keyboards use a rubber strip between the keys and the circuit board to detect touch and produce sound. Over time, this rubber strip can wear down, resulting in keys that either sound at full volume regardless of touch or don't produce any sound at all.
To replace the rubber strip, you'll need to purchase a replacement part, which is typically available online or from the manufacturer. Keep in mind that this process may vary slightly depending on your keyboard's make and model. Before beginning any repairs, unplug your keyboard and refer to the manufacturer's manual or support services for specific instructions.
Now, let's get into the step-by-step guide for replacing the rubber strip:
- Prepare your workspace: Place your keyboard on a stable surface, such as a table, and use a towel or mat to protect the surface from any scratches. Have all your tools ready, including a power screwdriver with a magnetic tip, if possible. A magnetic tip will make it easier to retrieve screws from tight spaces.
- Detach the keyboard from the stand: Remove the screws that secure the keyboard to the stand. The number of screws may vary depending on your keyboard model. Be careful not to misplace the screws, as you will need them later for reassembly.
- Access the back of the keyboard: With the keyboard detached from the stand, you can now access its back panel. Remove the screws from the back panel, which will vary in number and location depending on your keyboard model. Be mindful of any cables or connections that may be attached to the back panel.
- Disconnect cables and detach the front panel: Before proceeding, ensure you have unplugged all necessary cables to avoid accidental damage. Then, locate the computer ribbon cables connecting the power to the circuitry and carefully disconnect them. Now, remove the screws securing the keyboard to the front panel and detach it carefully.
- Remove the keys: The keys are typically organized in sets of octaves, with each octave held in place by several screws. Remove the screws for the octave(s) containing the faulty rubber strip. Gently lift or slide out the octave set(s) to access the rubber strip underneath.
- Replace the rubber strip: With the keys removed, you now have access to the worn-out rubber strip. Carefully lift or peel it off, being mindful of any adhesive residue. Clean the area if necessary, ensuring it is free of debris. Take your new rubber strip and align it precisely in the same position as the old one. Gently press it down, ensuring it adheres securely.
- Reassemble your keyboard: Follow the previous steps in reverse to reassemble your keyboard. Start by placing the keys back into their original positions and securing them with the appropriate screws. Reattach the front and back panels, reconnect any cables, and finally, secure the keyboard back onto the stand.
By following these steps, you should be able to successfully replace the rubber strip on your electric piano's keyboard. Remember to take your time, be gentle with the components, and always refer to manufacturer guidelines if you're unsure.

Fixing a broken spring
If the keys on your electric piano are not springing back up, the springs may be broken. Before attempting any repairs, it is important to note that doing so may void any warranty on your piano. If your piano is still under warranty, it is best to let the manufacturer deal with it.
To fix a broken spring, first, open the piano by unscrewing the top. This will allow you to access the keys and determine the problem. If the springs at the fulcrum of the keys are broken, you will need to replace them. Make sure to buy springs of the correct length for your piano. The measurement you need is from the coil to the end of the curvy part.
Once you have the correct springs, follow these steps:
- Remove the old springs by taking out the hammer rest rail. There are four pins holding the hammer rest rail in place. After removing these pins, you can slide the rail out of the action.
- Take out the old springs from the rail. The tail of each spring is fed through a hole in the rail and bent sharply downward.
- Insert the new springs into the rail. You may need to bend the springs slightly towards or away from the hammers to make the action feel normal again.
- Put the spring rail back into the piano and secure it with the four screws.
- Reattach the hammer rest rail by inserting the pins and screwing the action bracket back into place.
After replacing the springs, make sure to test the keys to ensure they are working properly.
