Using Fusion 360 to copy your car keys. via instructables

Disaster! My only copy of the my car key broke, I park on the street and have to move my car by Saturday 9AM today is Friday and I have to go to work. What to do? I could call an auto locksmith or take it in to the dealer but that would be expensive and take time. There has to be a better way, I’m going to upgrade my key into the 21st century and make a 3D printed copy with Fusion360.

Fusion360 is a powerful cloud enabled 3D modeling platform, and the best part if you register as an enthusiast it’s free!

The first step to making a reconstructed duplicate is to take orthogonal photos of the original. We need to get at lease one good shot of the side of the key and a basic shot of the profile of the key. These photos will be our guide for tracing and where to measure.

Lay the key down and get it as flat as you can. Try to get the light as even as you can. Take the photos from a bit further away than you think you would need to, taking them further away means the profile will appear ‘flatter’. The flatter the image the more accurate the trace will be.

Open up a new design in Fusion360, in the model workspace go to the insert tab and add in your best photo of the profile.
