Decode the original key with a caliper.
line up the keys, use the original as the stencil and spray paint it from straight above.
Use a file to get the bulk of the painted area, then finish off by cutting each cut to cut depth spec. For example, if you want a #5 cut, use a caliper, measure twice, cut once to a depth of 0.256".
