Rolling Code Vs. Fixed Code RF Remote Control
Remotes control send signals in code. When the sending code is the same as the code which is expected by the receiver, the relay will switch and the door, barrier or car will open. Remote controls with a fixed code will always send out the same code. A rolling code (or hopping code) always send out a different code from the one previously sent. The code changes every time because of the algorithm which is part of the remote control.

“Hollywood keeps before its child audiences a string of glorified young heroes, everyone of whom is an unhesitating and violent Anarchist. His one answer to everything that annoys him or disparages his country or his parents or his young lady or his personal code of manly conduct is to give the offender a “sock” in the jaw.... My observation leads me to believe that it is not the virtuous people who are good at socking jaws.”
—George Bernard Shaw (1856–1950)
“If they be two, they are two so
As stiff twin compasses are two;
Thy soul, the fixed foot, makes no show
To move, but doth if th’ other do.”
—John Donne (1572–1631)
“All our civilization had meant nothing. The same culture that had nurtured the kindly enlightened people among whom I had been brought up, carried around with it war. Why should I not have known this? I did know it, but I did not believe it. I believed it as we believe we are going to die. Something that is to happen in some remote time.”
—Mary Heaton Vorse (1874–1966)
“Imagine believing in the control of inflation by curbing the money supply! That is like deciding to stop your dog fouling the sidewalk by plugging up its rear end. It is highly unlikely to succeed, but if it does it kills the hound.”
—Michael D. Stephens. “On Sinai, There’s No Economics,” New York Times (Nov. 13, 1981)
