A comprehensive, detailed disassembly, repair and rebuild of a Suzuki HG-425e mini grande digital piano to fix keys that stick for free with minimal tools and no replacement parts.
Required tools:
Philips screwdriver
Triangular screwdriver or bit or something else that will fit
Fine-grained sandpaper or file
I used some pliers and a mallet, but they are not required
Note: this process took me a long time. I lost count, but it was quite a while. Hopefully, this video will help you to do it faster with no guesswork as to what the next step is.

My 400ex keys aren't like that. They have a green piece that holds the back of the keys down and rock on a little rod. 2 of them are broken. I am currently trying some structural epoxy for plastic. Any suggestions for a more "correct" fix?
Hello! Who could I hire to do this!!!!! I’m in Greenwood, IN!!!
Excellent step by step instructions. Thank you
I know I'm late to this party, but if anyone can help with the order of thebcounter weights, that would be a tremendous help. I should've taken a picture before i tried to rush through. Where each section goes and for the last set of 12, what the number order of each counterweight is. I figure this is a long shot but worth a try.
I just bought one of these pianos and will need to fix sticky keys. Fingers crossed that I don't need any parts since I can't seem to find any! Thanks for putting this video together. From the comments, it appears that this will help my husband and I get my piano fixed.
You saved our piano, was able to fix it with your guidance. Your video was so helpful. Although not the same (Behringer CDP2400), it was very similar. Thanks again!!!
Do you need to add any oil to rods when assembling
People who made it is to blame . Shame on them
I got a FP-S digital piano that had 90% of the keys sticking. This was a great a tutorial on how to disassemble the piano. For the repair I found a forum online that said to use a fiber glass rod sold at home depot for less than 5 Bucks and I was able to fix all the keys within 10 minutes. Took longer to take the piano apart than fixing all the keys. Thank you for sharing the dismantling process.
Fantastic video instructions! I stopped playing for years because of stuck keys, but now it's working perfectly. It took about 6 hours but worth it.❤
Excellent Video! Thank you for making this such a straightforward process.
Thank you, I bought the piano for $100. About a dozen sticky keys. Looks like someone had serviced it in the past too. Because of your video I was able to repair the entire keyboard and put it back together for my wife’s Xmas gift. Refurbished the cosmetics and put a bow on it.
Thank you again.
I just did this repair on a Suzuki HG-425e that had about a dozen stuck keys. Your video was immensely helpful. I disassembled and went through each counterweight, I used a fine rat tail file (lightly) on any key that did not pendulum back and forth easily on the rod, and I lightly sanded both sides of the hole. One thing I might add; when assembling each octave carriage, one needs to be aware the wide weight is a white key and each narrow weight is a black key. The little nub that the key presses goes opposite directions as well. I took me a while to realize they were different and the assembly started with “A” and went to “G#”. Once I understood that they went together easily.
Thanks again for this most helpful video.
