I might have this completely backwards, but it's my understanding that every time you lock or unlock your car, the rolling code changes randomly. If it just chooses a random number every time, then isn't it possible for another car to randomly %26quot;choose%26quot; that exact same number so that more than one remote could unlock it?Is it possible for the rolling code on your remote key for your car to match another cars?
Not quite that simple. The remote transmits two codes, one fixed, one rolling. Both must match exactly to operate the system.Is it possible for the rolling code on your remote key for your car to match another cars?
Yes, but depending on the maker of the remote there is usually about 1.2million different codes.
I wouldn't worry about it.
