it wasn't hard all i did was take off that black cover with the key switch in it, there is a little screw on cover for the key switch around where the key goes in, i took that off and slid my keyswitch out, i got a drill and drilled as big a hole as i could, then i took a pair of scissors and got the hole almost big enough, then i got the drill again and made the hole just a bit bigger by wearing it out, then i got a utility knife and cut a little notch in the top since the keyswitch has a notch on top, then just slid it in and put the screw thing back on and i was done. took all of 1-3 mins.
