This is a remote control for the sliding door on the passenger side (rear) of a C25 Serena. I lost it about 6 years ago, but found it while cleaning up at home. By the way, I have two of these. It was found in a dresser drawer, so it wasn't exposed to water. Since I no longer own the car, I haven't confirmed that it works, so I'm selling it as junk. Please consider this before purchasing. If you only want one, please contact me to discuss. #Nissan #NISSAN #C25 #Serena #RemoteKey
