Nissan keyless entry remotes with FCC IDs KBRASTU15 or CWTWB1Uxxx are among the fastest selling replacement keyfobs? There are two reasons for this. First, Nissan used the same two 3-button and 4-button remotes on almost every vehicle in its line for several years. Second, Nissan used the same remotes on both Nissan and Infiniti vehicles during the middle of the last decade.
What many people do not know is that the 4-button keyfob remote with FCC ID KBRASTU15 works for several different Nissan and Infiniti 3-button keyfobs, even some with different FCC IDs. For instance, the 3-button Nissan/Infiniti keyfob with FCC ID CWTWB1U415 can be replaced by the 4-button Nissan/Infiniti remote with FCC ID KBRASTU15. Of course, if you have a vehicle that came with a 3-button remote originally, the rear function button on the 4-button keyfob will have no effect when pressed.

If you are not sure which is the correct replacement remote for your Nissan or Infiniti vehicle, you can search by the FCC ID, OE Part number or Make-Model-Year of your vehicle on the Remotes Unlimited website.
If you are buying a replacement remote for a system that uses one of these keyfobs, you can find them at several auto parts stores.
