Make sure you keep the in order as it is hard to piece them back together if they get all mixed up. It is best if you number the keys in case they get out of order for some reason.
Remove the old keytops using a sharp chisel or a knife.
Lightly sand the key surface to make sure all the old glue residue Is removed and that there is a smooth surface for the new keytops.
Spread a thin layer of PVC-E glue on the surface and front of the key.
Make sure the sides of the keytop line up with the sides of the key. If the key is a little big make sure the excess keytop hangs over in the sharp natch as this is the easiest area to file and have it look good.
Let dry overnight. Using a flat metal file, you can smooth any overhang to make the keytop a custom fit to your keys.
