To begin we will have to remove the tray of the cards.

Remove the 2 Torx (T4) and with the help of one or more tines, we unhook the housing, and disconnect the flex that is stuck to the back shell.

Unhook the side buttons of the casing, take it off and disconnect it from the fingerprint reader.

Finally, we will apply heat to the area of ??the reader to soften the glue, and with a tool sufficiently thin we will take off the reader that we are going to change.
