The Secret Key is only used to get Rotom's other forms. Yes you can.
You don't.
Well, you buy a Webkinz plush toy that comes with a secret code. Your secret code is the key to making an account. You can just purchase secret codes without a stuffed animal, though.
You can't get the Secret Key in Pokemon Platinum without Action Replay, unfortunately. You can get Action Replay from most major websites.

You cannot change a Rotom's form without the Secret Key distribution in Pokémon Platinum however you'll be able to change Rotom's forms in Pokémon HeartGold and SoulSilver without the Secret Key distribution.
The Key The Secret was created in 1993.
No you cannot change rotom's forms without the key unless you have an action replay (i think)
