My home button on my PS3 isn't working?

May be...

I have two PS3 controllers and one of them works perfectly on my PS3 so it's not the system. The other controller works perfectly except for the HOME button. If at any time I press the home button, it shows the screen to turn off the console or controller and none of the buttons work on it up to that point. I don't know what's wrong. I tried resetting it and the PS3, but the home button just doesn't seem to work. Does anyone know how to fix it or what to do? Thanks in advance.

you cant. youre going to have to get a new one

dont throw away the other one because you really only need to get a new one if you NEED to use the home button
