the box remote control how can i fix it

my remote control off the box seems to be broken.when i try change channels it just flies thru the channels,when i use the epg the same thing the epg menu keeps on flashing ,i tried changing the batteries but the same,when you press the keys nothing happens at first then when you do get a menu it keeps rolling thru ,any ideas or help as to whats wrong,i am hoping it is only the remote and not the box,but as i said it seems to be the remote sticking first then the channels wont stop,
