OpenSCAD script to create an Audi high security key HU66A-P. I created this based on taking measurements from my physical key and using the attached spec sheet, which I acquired from a locksmith.
This key will fit the following cars:
This key has 8 cuts at 4 different cut heights. In order to decode the key, start from the cut furthest from the key blade tip and try to identify the key code. The closer the key is to the groove, the lower the number. For example, the key in the STL file has the code 3,3,4,3,1,2,2,1.
Go into OpenSCAD and enter the number from your decoding. Double-check to make sure it looks like your key.
Some vehicles that use this key have a transponder. My car doesn't have a transponder and the key works just fine in my car. Have fun!
