Can Piano Keys Be Replaced?
Yes. Our process of replacing the top portion of the keys can take a few hours to possibly a day. The following are the steps we take to complete this task:
Step 1: Remove The Cabinet Parts
Open the front and top panel. Using a screwdriver, take out the fall board. If any other parts of the cabinet will restrict access to the keys (end blocks, key slip and/or key block), remove them.
Step 2: Number Each Key
Before taking the keys out, number them to keep track of where they are positioned. This will make it easy to remember where they go once they have been fixed.
Step 3: Remove The Damaged Keys
Using a thinly sharp chisel, carefully remove the top of the keys. Work the chisel between the wood and the key material by going slowly. Take a razor blade to clean any old material and dirt on the front of the key.
Step 4: Lightly Sand The Key Surface
Remove any old glue residue by lightly sanding the key surface with a medium sandpaper. This will smooth the area before adding the new key top.
Step 5: Apply PVC Glue
PVC Glue is highly recommended to merge the new key layer on top of the wood. Add a thin amount of it on the top of the wooden area of the key and to the bottom of the new key layer.
Step 6: Position And Clamp The New Key
Before clamping the key in its position, make sure:
Once the previous steps have been complete, firmly hold the key for one to two minutes. A set of clamps can make this a lot easier.
Step 7: Check The Fit And File The Edges
When the glue dries, check to make sure the edges of the key top are a perfect fit. If not, then use a small metal file to smooth out the edges.
Step 8: Reassemble The Piano
Test out the keys by playing a couple of melodies. If everything feels good, put the piano back together.
