Howto: Hack a Nike+iPod to Make a Wireless Car Key

Hacker Nathan Seidle has rigged his car so that his Nike+iPod pedometer unlocks the doors wirelessly as he walks up to it.
“I hate keys,” he writes. “I am on a mission to dispose of them all.”
Seidle already uses keypads and wireless RFID cards to get into his home and office — the last key in his pocket is for his car.
So Seidle took a Nike+iPod sensor — the pedometer/transmitter that normally goes into your running shoe — and rigged up a simple proximity sensor inside the car to detect when it approaches. The Nike+iPod sensor is constantly transmitting a unique ID, which the car uses to identify Seidle and unlock the doors. He keeps the Nike+iPod in his pocket.
Seidle made the proximity detector inside the car from the Nike+iPod receiver (the part that normally plugs into the iPod) and an Arduino Pro Mini microcontroller board, made by his company, SparkFun Electronics, plus a few other bits and pieces.
The system, which Seidle calls the iFob, is an intermediate hacking project. He’s posted a detailed tutorial on the SparkFun website.
Unfortunately, the iFob doesn’t start the car; it just unlocks the doors.
“The system now works great!” Seidle writes. “When you’ve got a handful of stuff, it’s great to know the doors will automatically unlock as you approach. However, I still have use a key to start the car. The next step is get a big red button wired up for button start so that I don’t have to carry my key. Someday.”
