Nissan keyless entry remote controls with FCC ID KBRASTU15 were used on many Nissan and Infiniti vehicles for several years. In fact, apart from a few Ford and GM remotes, no FCC ID appeared on more vehicle applications than KBRASTU15.
There are three styles of keyfobs with this FCC number, a 3-button version with lock, unlock and panic buttons; a 4-button remote with the same buttons plus a trunk icon; and a 4-button keyfob with a liftgate button icon. All of these parts are interchangeable.
