Key Template
thingiverse
This is a standard key template. To make it fit your own to door, import the model into Onshape and attach a picture of your key. Draw the outline of the key and remove the material afterwards. You can also use a file after you have printed the template key. I printed it with 0.1 mm layer high and it worked as a functional key in my door.
