The Founder's Key is an item that used to open The Vault in the Pet Store. It is found in the sunken ship, right beneath Burt's new station spot.

How to obtain

After diving into the area of water where Burt is stationed, you then dive down into the Sunken Ship and search for the three pieces of the key.

The first key is located straight ahead of you, in the small sandy cove ahead.

The second key is located near the wooden staircase section, close to the first.

The third key is located on the very top of the highest tree.
