Turns out you can mod the Nike+iPod kit to make your car doors unlock when you walk close enough to the vehicle. And of course, the doors lock once you walk away. You only need to take your keys out to start the engine.

Totally cool, the setup involves hooking up the iPod adapter to custom electronics, and pocketing the footpod. The full how-to is available at Sparkfun, and includes details on how author Nate had to actually weaken the radio receiver of his Mazda so that the car wouldn’t automatically unlock while he was walking around the office (he wrapped part of the assembly in foil).

Obviously, some experience tinkering around with electronics is a prerequisite. Anyone here got that? Custom component sold on Sparkfun—an iPod serial board—also required.
