"Well that's why i don't like keyless vehicles, it's easy to stole it with some wireless signal emulator In the end the principle is same like wireless garage door opener, some thieves can hijack it very easily like no effort."

"Do you not know what rolling codes are?"

I responded to the second quoted comment asking (because the article is about car theft) how rolling keys prevent relay (repeater) attacks on keyless entry vehicles. There are several people in this thread who are comparing car keys to garage door openers, however, that's not what my conversation with the person above was about.
