As pianos age, one of the things that often needs to be replaced is piano keytops. With the right parts, tools and instruction, the average person can accomplish the task of replacing the old, worn keytops. The video below shows the procedure for replacing piano keytops.
If you are keeping the old fronts and putting on new keytops without fronts, the only difference from the installation procedure for the keytops with fronts will be that you'll need to line up the front edge of your keytop so it hangs off 1/16" from the key front. Doing this will ensure that you have the proper amount of overhang on the keytop.
