It took a few minutes for the 'relay' portion of what you just wrote to click.

So, in theory, if you wanted to steal a REALLY expensive keyless car you could have two devices connected over a mobile data connection that just relays communication with the keyfob. You put one device near the owner of the fob, so in his office, and you keep the other. Then you can just walk off with the car.

Yikes.

Yep - here's a presentation on these relay/repeater attacks by some researchers who actually build some: http://media.hacking-lab.com/scs3/scs3_pdf/SCS3_2011_Capkun....

Yep, that's pretty much it.

Although sometimes you can even skip the second device and just have the one near the keyfob.
