new and old key blanks interchangeable ?
my 81 has the small black key with the crests missing works perfectly but was thinking of ordering an original blank i fancy the newer bigger red key is the working end of the key the same through the model range or different?

As far as I know the only difference is in the length of the key shaft. The longer shaft is for cars with factory alarm systems. The longer shaft engages the tumbler that activates the set/cancel contact for the alarm system.

They can supply the keys cut on original blanks from the OEM supplier to Porsche. Those keys are "original." They also have non-OEM blanks available for a lower price.
