Abstract: A device and method for installing a keycap spring in a computer keyboard having a vertical tube and a base for mounting the keycap spring at the bottom of the vertical tube. The device comprises a handle, a shaft with a tapered head connected to the handle, a sleeve which slides over the shaft, and a sleeve spring connected to the sleeve which slides over the shaft and fits between the sleeve and the handle. The keycap spring is inserted into the sleeve where it fits over the tapered head of the shaft. The tool is then inserted into the vertical tube and the end of the tool is placed over the base. Downward pressure is then applied to the tool, causing the keycap spring to be compressed inside the sleeve. When the keycap spring is fully compressed, the downward pressure applied by the user forces the bottom end of the keycap spring onto the base. The tool is then extracted. The keycap spring is held by the base, causing the spring to slide out of the sleeve.
