After getting the national Dex go to stark mountain then the first time you go team galactic should be there then after they arrest the old guy go to the trainer cafe then talk to buck after that go back to stark mountain and Heatran will be in the same place where they arrested the old guy.
You must have beaten the elite 4 Pokemon league, then check your Sinnoh Pokedex and see if it is full.

In Pokemon platinum there should be 210 Pokemon.
When you obtain the National Dex, go to Snowpoint City and talk to the guy next to the boat.
You'll arrive at the battle grounds and then battle a load of people .
When the routes to the Resort Area and other areas are unblocked, head to the mountain.
Then beat team galaxy, go through the mountain, go out of it when you've go to the last bit, and finally go out again.
Then talk to buck.
Go inside again and you'll meat Heatran!
Heatran is in the Lava Zone. You have to play the attractions, and I think he will appear around Camerupt, the huge cow with three circles on his sides of his body. It is near the object that makes gold/iron tops and gold/iron bar. a way to get there is pass the dangerous Torakoal, or go to that place with the circular pathaway.
You don't type in a password, you beat all the high scores in Rhyperior's Bumper Burn.
