here are the installation instructions. I'm unclear about what to do with the key fob? i see it needs to be in the key hole for manual transmissions. What about automatics like on the 335d and other e90 automatic transmissions? It looks like you wind the key and key barrel with the coil of wire so the key is always in the car. Then you rely on the key fobs supplied by Fortin.
