Things You'll Need
Instructions
Open the lid of your Zippo lighter and pull the interior housing free from the metal shell.
Turn the interior housing upside-down and loosen the golden screw with a flat-head screwdriver.
Pull the screw away from the interior housing, thereby revealing a long spring tipped with a bronze bit of metal.
Lightly tap the base of the interior housing against a hard surface to dislodge any remaining flint bits.
Insert the new flint replacement rod into the bottom of your internal housing.
Reinsert the spring behind the flint rod, with the bronze bit of metal pushing against the base of the flint. Compress the spring until you can tighten down the golden screw once more with the flat-head screwdriver.
