Your old remote must look exactly like the one in the picture and either have the CH13B – ZG3 model number along with a green ZG3 sticker or have a CH13B – AS model number. if you no longer have your original remote, you need to look under your bed and find the model number sticker, which will say M9X9. If you are unsure, or do not see any of those stickers, reach out to us and we can help determine whether this Remote will work or whether we need to do a Conversion Kit. If your original remote was gray, this replacement will not work.
