How to Fix a Casio CDP 220's Rubber Hammer Cap without Replacement Parts

My Casio Keyboard / Piano (CDP 220) recently broke one of its "G" keys recently and after opening it up,and doing some research, I discovered that I needed a component called a "hammer cap" which acts as a cushion between the key's plastic bottom and the lever which activates the sound. These rubber hammer caps are hard to find and I don't even know where to begin looking. I thought that if I were to bring my keyboard to a service center, it would cost me a lot of time, and money, and not to mention all the hassle and perils of going out in a middle of a pandemic. So I found a fix using duct tape which you'll see in the video. All in all, you it will not cost you more than one 5 dollars to fix this, and only about 2-3 hours of your time.
You will need:
1. Duct tape
2. Super glue (optional for reinforcing duct tape adhesion)
3. Scissors
4. Screwdrivers (for putting apart the pieces)

Thanks for unselfishly sharing your ideas to us

You're a genius! Thank you very much for seeing the problem from the opposite angle. I had already managed to repair some hammer caps by stealing them from keys at the extreme ends of the paino, but now the piano is getting old, the hammer caps just fall apart when I try to take them off, and it's impossible to find them for my old Casio PX-110. I found some thick double-sided tape and with two layers of that I got the height I needed. Thanks for a brilliant suggestion.

Glad I was able to help

This is amazing. I could repair the broken key board to normal. Thank you so much for this video.

Very useful practical way of fixing the keyboard.

Thanks, your video is very useful, from Russia with respect!

[@PoliGoat11]

Спасибо!

[@deeegol]

Wow, that's a very creative and effective way of fixing the problem. My only question is will it affect the 'weight' of the key when you play them? Will it matter how thick or how many layers of duct tape you put on each key?

[@user-he7bt7uv6z]

Thank you

[@EuniclaireMaeAnneHerrera]

Another trick is when you open the piano, I'm sure the broken hammer caps are is still there. What I did was I put the broken pieces together using super glue and put it back. It works well because the caps are whole again and does its purpose.

[@breernancy]

Oh this is great ! One of the "why didn't I think of that" solutions! Not sure the tape is needed on both sides tho - just the side closest to the top of the key? My only concern would be the metal tip of the hammer rubbing on the tape. The rubber cap serves to absorb the impact of the hammer and also reduces the wear and tear of the tip on he note. Perhaps one should use that white lubricant to reduce the friction and wear?

[@PoliGoat11]

Thanks! Good question though. The answer is that you'd want the piano key to also be snug as it lifts up. If there's no tape on the bottom, once you let go of it, the key would rise up off of the key levels and take a bit of a delay popping back down. Also, another concern would be that it would make noise with the bottom still being bare plastic hitting the tip. As for the wear and tear, duct tape is way more durable than the rubber. The surface of the duct tape isn't very rough too, so I wouldn't worry about it damaging any other compontent.

[@RenanteNate]

you can use glue gun to replace the hammer caps. you just need to trim the glue to make a similar shape to that of the hammer cap. The hammer caps have specific design shape.

[@EuniclaireMaeAnneHerrera]

Nice trick. I also tried putting stick glue on it. Wasn't able to follow the shape well, keys drop so hard😆 i removed it. I saved the hammer caps by bonding using super glue. Tadaaa!

[@marwensassi2351]

Love this video ❤️❤️❤️How long does it last before it begin to do that problem?

[@PoliGoat11]

A loooong time. Duct tape is more resilient than rubber.

Boa sua idéia. Eu reparei cortando borracha eva de tatame. E colando na tecla.. na parte q entra a borrachinha do martelo. Gabiarra forevis

[@seanpatrickperfecto7426]

This just happened to my casio. Would you know how much it would have cost you (Php) if you brought it to an authorized repair?

[@forevergoodnews5581]

Two questions: 1. Could you have just replaced the broken cap with the one you removed from the lowest key? 2. Could you have just switched levers instead? I mean get a lever that still has a cap on from a key that's hardly ever played? Thanks for this video, by the way.

[@PoliGoat11]

1. I thought of doing that, but I wanted all my keys to be functional since the pieces I play, Lizst, Chopin, Beethoven use the lowest and the highest notes. 2. No, the levers are attached to the electronical components. The keys are attached to the levers. The problem is that the key gets loosely attached to the lever because of the broken rubber cap. It's not about the black levers. They can't be removed.

I have casio cdp s100 plz keyboard contact strip is removed plz help me to connect it

[@Johnson_Samuel___]

How can I purchase it..please tell me

[@RenanteNate]

Does it not add extra annoying weight on key? How about gluing a rubber sheet using acrylate? Rubber serves as impact absorber

[@PoliGoat11]

Nope! It feels exactly the same. You won't be able to tell the difference. If anything, duct tape is even lighter than rubber. After all, it's just strips of it.

[@aishafasih]

I have the same piano and one of the key is dead. You think it’s an easy fix.? I’m just nervous about all the screws... :s

[@PoliGoat11]

Opening it up is easy. Look at these links kzbin.info/www/bejne/hJzaoWRjgs-Yic0 www.ifixit.com/Guide/CASIO+CDP-230R+Key+Replacement/98338 and so long as you follow the steps, you'll be fine.

[@deeptiramchiary8183]

Thanks for the link for opening it. I have the same piano with same problem. Gonna fix it myself. No service center in my town.

[@Sir_Niko_Gil]

How did you remove all the parts apart?

[@PoliGoat11]

With a screwdriver. :P

[@jimmybaniaga8516]

U can use or put silicon too

[@PoliGoat11]

If you have it, sure. But anyone can get a roll of duct tape.

Watch other video, there is a better way to do that.👍

[@airwind1961]

video is making me dizzy.

[@Nazar-78]

Long ago I first had one of the keys with the hammer cap deteriorating, then followed by 3 and now 5 of the others. It's due to moisture or cleaning liquid seeping into the keys. I actually fixed them differently because there's a noticeable weird feeling and odd clicking noise when you play if you use different materials. So I cut a few pieces of rubber feet ( something like www.pinterest.com/pin/747667975619507420/ ) at the appropriate thickness then glued them into the top/bottom slot of the white key.

[@PoliGoat11]

Good idea! Whatever works, I guess. But just make sure that it sticks. I chose duct tape because I was more sure of its ability to stick.

[@deeegol]

Wow, that's a very creative and effective way of fixing the problem. My only question is will it affect the 'weight' of the key when you play them? Will it matter how thick or how many layers of duct tape you put on each key?

You barely feel the difference. :)
