If you carry a ring full of keys (one for the entry, the backdoor, the garage, the truck, the office, etc.), distinguishing one key from another can be difficult, especially in the dark. Fine Homebuilding reader Eugene Capaiu from Rolling Hills, Calif., solved that problem by drilling an off-center hole in his house key. When he holds his ring up, the house key pops out at an angle, and he’s in the house in no time.
