Sick of the sound of jangling keys and dog tags,we have found a clever way to silence them. Fit a piece of heat shrink tubing over the head of the key, heat shrink it to the key with a heat gun, and then trims off the edges. Though you could use the many colors of heat shrink tubing available to color-code keys, we kind of like the transparent look—especially for things like dog tags that you still need to be able to read. Sure beats wrapping them in duct tape!
