Found it:
That’s true: Miller and Valasek had worked on their Jeep hacking exploit for over a year. “The software manipulation addressed by this recall required unique and extensive technical knowledge, prolonged physical access to a subject vehicle and extended periods of time to write code,” reads Chrysler’s statement.
That's how hacking works. You get an example of what you want to hack, then you pound away at it until you find a vulnerability.
Once the software is written they can use it to access any vehicle that's vulnerable to the exploit. They don't need physical access to EVERY vehicle.
