> For this new attack to work, all that is needed is a single button-press capture from the keyfob, without any jamming. Just from that single capture, it is able to emulate all the keyfob's functions, including lock, unlock, and unlock trunk.

If I don't press the buttons on my keyfob am I safe from this?

The only keyfob functionality I normally use is that when it is outside the car but within about a meter of the door handle the door can be locked or unlocked by pressing a button on the door handle.
