The short clearance inside this case almost got us down, until we pulled out the flexible shaft attachment from our 54 Bit Driver Kit.

With yet another rarely used tool in hand, we snake a Phillips #0 bit into the case's interior, pull out a few screws, and free the button board.

While the button board itself is easy to replace (with the correct tools), it's a bit of a bummer that you have to take most of the device apart to get to it.
