Before you can change Rotom’s form in Pokémon Brilliant Diamond and Shining Pearl, you need to catch one and obtain the ‘Secret Key’. Note that this can only be done after defeating the Elite Four and obtaining the National Pokédex. To catch Rotom, head to the Old Chateau inside Eterna Forest, near the entry point to Eterna City via Route 205. You’ll need to use Cut on a small tree to reach it.

It needs to be nighttime in-game for Rotom to appear, which is considered to be any time after 8:00 pm. Head inside the Old Chateau and take the stairs to the left and enter the first door on the North wall, which is the second door you’ll see. Then, enter the second door to the left and press the ‘A’ button when standing in front of the TV and select ‘Yes’. A wild Rotom will appear, which you’ll then need to catch.

After catching the Rotom, you will also receive the ‘Secret Key’ item, which is needed to access the secret room that allows you to change Rotom’s form.
