Dig it.... go to Office Depot (or Office Max, etc...) and pick up a Pentel mechanical pencil and a package of replacement lead. Make sure that replacement lead says HB (not 3B, or something else.) Make sure that the Pencil has a eraser, to clean up the first 4 attempts at unlocking the chip. Also GET A MAGNIFYING GLASS!!!!!!!!!! Breathe deep, have plenty of light, and try not to shake too much. Once you look at the L1 leads, you'll realize that they are much smaller than they appear in the pictures posted on websites. This is not a difficult procedure, just an intricate one. You'll be fine.
