If your old remote model did not look exactly like this new remote this may not work. Your remote may have a couple of extra buttons, but it will not affect functionality. This is not compatible with any of the older generation simplicity models. Text me with any questions! 

We also have started carrying a generic version which will work with this base and have all of the same features (actual pressable buttons instead of the capacitive touch microwave style buttons that this one uses) for $40 less. Contact us if interested
