Where do I get the key card in Silph Co building Pokemon quest?

You don't actually need a key card to enter the Silph Co. building in Pokémon Quest. You can simply walk in!

However, there is a key card inside the building that unlocks a secret area and provides access to some useful items. To get the key card:

1. Complete the main story: You'll need to progress through the game's main story until you've beaten the final boss.

2. Return to the Silph Co. building: After completing the main story, return to the Silph Co. building and you'll find a new area accessible with the key card.
