With so much wireless technology around us these days, information falling into the wrong hands is getting easier and easier.

One new way thieves are stealing cars is copying your wireless FOB signal and using it to open and turn on your car.

So how do you defend it? Wrap your keys in tinfoil! Yes...it's true. The tinfoil will act as a barrier and prevent thieves from stealing your signal.

While it is not 100% guaranteed to work, it is an inexpensive way to tip the scale in your balance.
