if the hooks have come out of the slots, only, then its not an issue.
dont know what honda would charge but any road side mechanic would do it easily for 500 rupees.
care is to be taken while pulling the plastic part of hand brake console (rear ash tray side).
the hooks and cable is just like brake/accelerator cable of bike/car.
and in case the you need to replace the cable, the best quality comes for Rs.1700 that they clain to be genuine.
I HOPE IT HELPS.
