Harbor Breeze Extra Remote

I installed a ceiling fan in my living room; prior i had lamps lighting it that are tied into the switches vie power outlets, i did not tie the fan into those switches. The fan has a remote which i have mounted to the wall by one light switch, and would like to mount another by the other switch, how ever i am having issues finding another remote that will work with it, all that i have found are new remotes to put onto lights without them.

information on the remote: FCC ID: KUJCE10512 MODEL: TR258A STICKER ON REMOTE: A30462

Ceiling fan is a ceiling huger, light and fan by harbor breeze, i dont have the box any more, so unsure how to get the model number for it
