How do you take apart a CD player?

Find an old CD that you don't listen to and whose case is in better condition than the one you're trying to replace.

Put your fingers under the part that holds the disk and pry upwards. Move your fingers down the length of the case until the bottom has popped out.

Take out the paper backing in the CD, but remember which way it went in. Also do the same to the cover "booklet" and the CD itself.

Put them in a separate area or throw them out and repeat steps 2-5 with the new CD. Also put the parts in a separate area.

Place the paper backing of the new CD into the back side of the old CD case, then snap the old disk holder into the case.
