You can't. It has to be Platinum. If you get Platinum, you need the Secret Key. You can't get that anymore unless you have an Action Replay.
mysteri gift
You cannot get the secret key in pearl or diamond version. It was only available for a limited time via mystery gift on platinum version from June 2009 to July 2009. So, it is now impossible to obtain even in platinum version. Sorry, but you lucked out.
You can't get the Secret Key in Pokemon Platinum without Action Replay, unfortunately. You can get Action Replay from most major websites.

You have to obtain the secret key and head over to the first floor of Team Galactics HQ. It is by the TV and the machine equipment by the reciptionist. Just push "a" and you will have the option to use the secret key. As for obtaining the secret key there are only two ways I know of: 1) wait for a Pokemon event in your area to receive the secret ket 2) purchase an action replay for the ds and find te code for the secret key online
