    • If it is the actual main screen panel control buttons that need to be replaced, grab the front panel as seen in the picture and push from the outside in with little pressure as if you were regularly trying to use the button.

    • If the buttons aren't broken and the phone just isn't getting the signal when the button is depressed, try replacing the actual electronic board under the buttons replaced in the last step.

    • Using the plastic opening tool, insert just under the electronic board and apply slight pressure upward.

    • It is snapped in place so it may seem like you have to add a little more pressure than needed. But don't worry, you won't break the board and it will pop right out.
