Fabrizio Giordano used some items in his kitchen to allow him to remotely unlock his apartment door. When you are in an apartment you will quickly eat up your damage deposit if you start drilling holes for wires and screw things to the walls and doors. With a bit of tape and some wires hanging in some creative ways Fabrizio was able to mount his unlocking mechanism so that he can now use his phone to do some fancy remote unlocking. The taped on wooden spoon might look a bit unsightly but when you compare it to the professional method which usually involves cutting in a door strike into the frame of the door I think he selected the best method.
