A few days ago, we wrote about a 3-button remote (Remotes Unlimited part 324-1324) used on the 2000 and 2001 Nissan Altima that has FCC ID KOBUTA3T and lock, unlock and trunk buttons. See “2000-2001 Nissan Altima Keyless Entry Remote with FCC ID KOBUTA3T” at this link. We focused on that part because we had an inquiry from someone about this specific Altima remote.
However, there is another keyfob (Remotes Unlimited part 525-1525) with FCC ID KOBUTA3T that was used on many other Nissan models. In fact, RUI part 525-1525 was used on vehicles dating from as early as 1995 all the way through 2002. And it was not only used on Nissan vehicles, it was also used on Mercury Villager vans and the Infiniti QX4. This widely used keyfob also has three buttons, but the third button is a panic button rather than a trunk button. Several Nissan part numbers are associated with this remote, but the most common are 28268-1W300, 28268-2Z021 and 28268-9B921.
All of the applications for both of these remotes with FCC ID KOBUTA3T are user programmable.
