Hackable - Is There a Way to Get a Wireless Key Fob?

Craig called in with a question about how easy it might be for some one to catch my car that has a wireless key. A lot of these key fobs, what they do as they will constantly send a radio signal. By amplifying that signal, they can basically clone the signal and at least have enough to start the car and then make off, make off with the vehicle. We certainly did an episode a year or two ago where we were able to get into the car, but not start the car. But i guess, i guess technology and hacking technology come away.
