First we will remove the card tray.

We take off the back cover with the help of a plastic pick, and with a finger we will press the fingerprint reader and take it off.

You can apply a little heat to soften the adhesive that holds it, and so you can peel it off more easily.

We remove the thirteen Phillips screws (PH # 00) that hold the intermediate casing, and with the help of a flat tool we will unhook it.

We disconnect the battery to work with greater security.

Now we can disconnect the damaged fingerprint reader that we are going to replace.
