in silent hill 3 how do get in the both to open the lock gate after the hunted house?

Answer 1

You have to be more specific - do you mean on the merry go round?
You need to find a chain, attach it to the center of the merry go round, then attach it to the gate. Then start the merry go round.

I think the chain is in the outdoor theater area.

Hope this helps - I love this game.
