This is an authentic Leggett replacement remote.. you Match up your buttons exactly. Some old Gen t-120 other remotes look the same but do not have the light button in the middle and it will not be compatible. The version that we sell of this exact remote has a brand new battery installed, with the option to replace the battery if needed down the road. Due to supply chain issues, the remote received may be black or silver but the functionality will be the same.
