Sounds like for the new Fiesta and Focus model Ford is rolling out a new secure type of key fob

I wonder if it is possible to use one of these for the USDM cars. The technology basically has the fob turn off if it has not moved in a while, preventing thieves from snagging the signal/code by just walking past your desk or house. They can still get the code if you are walking around or actively unlocking your car.
