Insert an opening pick about 0.5 inches (~12mm) under the bottom corner of the display, near the headphone jack.

Keep a close eye on the button's ribbon cable as you insert the pick. The cable is fragile and very easy to tear. If the pick is hard to insert or the cable starts to stretch, apply more heat.

Leave the pick under the display to prevent the button from re-adhering to the display.

If you do break either of the capacitive buttons or ribbon cables, you can replace the daughterboard assembly, which includes new capacitive buttons.
