Did you know that Nissan keyless entry remotes with FCC IDs KBRASTU15 or CWTWB1U733 are among the fastest selling replacement keyfobs? There are two reasons for this.
First, Nissan used the same remotes on both Nissan and Infiniti vehicles during the middle of the last decade. (There were no brand markings on these 3-button and 4-button remotes.)
Second, Nissan used the same two remotes on almost every vehicle in its line for several years. The math is simple – when the same remotes are used on more vehicle model years, the replacement market is bigger for those keyfobs.
