Hi! My name is Jay, I have an 82 924. My pal Tony has an 81 Scirocco, with a 1.8L 16V. We also found out that VW/Audi keys work in their Porsche cousins. My Porsche Ignition key, would open his Hatch, and start the car, my door key opened his passenger door, and vice-versa. Just thought I would make a note of it. Jay
