I recently moved into a new house, and as part of trying to understand (at a basic level) how everything is wired and plumbed together I've come across a metal box, on the wall of my kitchen. What is likely to be in it, and how can I get in to check? None of my tools seem to be able to open the 'screws'.
My kitchen has been converted from the garage. It's not clear how long the box has been there. It might be from when it was a garage.
I've been searching for the control unit of the house alarm, but not found it yet. Could it be in the box, and is that why it's metal and hard to get into?
