All Secret Room Locations for Secret Key in Pet Sim 99

Secret Keys were added to Pet Simulator 99 with update five, allowing the player to open various locks scattered around in different worlds.

To use your Secret Key, walk up to any large padlocks covering a door and press "E." This will use up your Secret Key and give you access to the loot inside.

All Secret Room Locations

There are currently three Secret Rooms to use the key on in Pet Sim 99.

World #15 Lock - Purple Tree

Use the key on the lock covering the door on the giant purple tree. This room contains a booth called "Crazy Deals," where you can pick one of three random items.

World #33 Lock - General Store

This lock is located at the General Store. Upon using your key on the door, you will enter a room where you must pick one of three chests for random loot.

World #58 Lock - Fairy Castle

This lock is located on the huge Fairy Door on the pink castle at the top of the short path. You can spin a spinny wheel in this room for a random prize.

So far, these are all locations where you can use a Secret Key in Pet Sim 99, but more doors will most likely be added with future updates.

All secret rooms drop similar loot from common rare items all the way up to Superior items like enchants.
