keygen

Tools for generating physical keys.

How it Works

Get some nice pictures of the side and tip of your key. I recommend a flatbed scanner.
Trace the key outline, warding, and embossing in Inkscape
Use the provided Inkscape plugin to convert the paths to OpenSCAD polygons.
Look up online the various parameters of your key, such as plug diameter, cut depths and locations.
Use the provided OpenSCAD functions key_code_to_heights, key_blank and key_bitting to generate a 3D model of your key.
Send the key to be 3D printed.
