His home is a cave located on an island with a Shinto Gate erected in the ocean in front of it. There are two entrance. The main entrance that can be opened when the bell is rung (see below), and an opening found underwater leading out to sea.
As Godzilla gains more of his essence's abilities, parts of the cave will start gaining more plantlife.
On the island itself, there is a rundown path, lined with Shinto gates that lead to a small shrine with a statue of a large lizard on either side.
Godzilla's key is a bronze bell commonly seen at Shinto shrines. He doesn't carry it with him, it is just a bell somewhere on the island that can be rung to reveal the cave. That means anyone can use it to open his cave.
