For those who are lost, the idea is to make a sonic screwdriver- a pretty much omnipotent tool from the BBC series 'Doctor Who' - that can lock and unlock the car, as well as popping the trunk and setting it to panic. If you've seen the show, you already know it would be awesome- if not, just think of it as a technological magic wand.
Unfortunately I can't claim this as my idea, it was just a random comment I read. However, it still sounds like an awesome idea, so I'm wondering, would it be possible to modify or get a remote chip for our car that would fit into an area about the size of an AA battery?
