Replacement Keyless Entry Remote Keyfobs with FCC ID CWTWB1U821

The FCC ID CWTWB1U821 appears on 3-button remote transmitters used with factory keyless entry systems that were installed on both Suzuki and Nissan vehicles. The remotes look identical from the front. However, on the back of the Suzuki keyfob, where the FCC ID is shown, it also says “Code A”. So be careful when you buy a 3-button remote with the FCC ID CWTWB1U821 to be sure you are getting the correct part.
