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.
If you wanted to spend $20 more, we also sell this exact same remote with a silver or black color with the removable battery cover. One battery will on average last between three and eight years depending on use.
