|Silph Co. is composed of 11 floors of teleportastic fun, including
28 trainers and a ton of items.
The Card Key is on the 5th floor at the bottom of the screen.
There is a Rocket Member guarding the entrance to that hallway and a
teleporter in the way. So, to get into the hallway you must go into
blocking teleporter, then teleport back (so that you're standing on
the teleporter). Then go down 1, fight the Team Rocket Member if you
have not done so already, and go to the right to get the key after
the fight. With it you can open every door in the building.
Make sure you get all of the items and fight all of the Rocket
members, the battle with Sabrina later will be easier.
On the 11th floor you'll find that you can't reach the president
of Silph Co. and must somehow warp there. The correct warp pad is on
the 3rd floor past the 1st door to the left (Right in the middle of
the floor). After rematerializing you'll see that a familiar face is
waiting for you. Another annoying battle (not to mention
conversation) is about to begin, only now he has some pretty wicked
After defeating him, talk with the person to your left and
they'll give you a Lapras for saving them.
