Saab 9-5 Keyless Ignition + Remote Start

When you have a somewhat rare car, there’s not a lot of aftermarket support. I wanted a remote start for the cold winters and no one seemed to offer one. I endeavored to figure it out myself and realized along the way that I could also convert the vehicle to a keyless ignition so that I would no longer need to carry a car key, only the fob.

What follows is phase 1 of the project. Phase 2 will add support for Bluetooth activation.
