Headline is confusing: the vehicles are not sending signals, key fobs are sending signals (on click) and those signals do not change, so if someone records & plays back your "door unlock" signal they can unlock your door. The way this was written, I thought cars were sending signals to one another somehow. Furthermore, the "vehicles sending the same signal" refers not to a single signal shared between vehicles. It means vehicle X consistently relies on "the same" (unchanging) signal X, vehicle Y consistently relies on "the same" (unchanging) signal Y etc. As written, it sounds like every single honda of the same year & make uses one, shared signal which is not what is meant, unless I'm mistaken.
