I use the Keyhole Toolpath Gadget that is built in to Vectric VCarve Pro and Aspire ( VCarve Desktop may not have Gadgets). Once you have it configured with the size of bit you are using and the orientation of the keyhole, it is an easy cut. It saves your settings so it is ready the next time you need a keyhole.

Can't get much easier than that.
