First, we will apply heat to all the edges of the back cover to soften the adhesive that holds it.

With the help of a fine tool, we will open a small hole through which we will insert a plastic tool, with which we will be less likely to damage the casing.

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

We disconnect the battery to work with greater safety.

We remove the Phillips screw (PH # 00) and the Standoff that prevents us from removing

the plate, and once removed we can lift it.

Finally, we only have to remove the cover that protects the hole of the pushbuttons, take off the flex area with the contacts, remove the interior shield, and the keys will fall off, and now we will only have to make a small lever in the shield in the one where the push buttons are stuck.
