Well, after having some issues with volkswagen keys, I decided to get faster than my keys, by creating keys by myself, that uses the original metal part, meaning you just print the casing, it pauses, add the metal original part, and resume the print !

There's a little hole made to secure the metal part by using a cheap random small screw, of course it's optional, but it's here just in case !

IMPORTANT NOTE : I'm still working on it, it's not perfect yet ( depending on the models )
