Talk to 32 people underground and mine for an Odd Keystone. South of Soleacon Town put the Odd Keystone in the Altar. Then, catch your Spiritomb!
You can't. The Odd Keystone is only obtainable in Diamond, Pearl and Platinum. You will need to trade a Pokemon with an Odd Keystone to get it on SoulSilver.
You walk up to the crumbled tower and press "A" and it will say the odd keystone looks like it will fit.

To get the Odd Keystone in Pokemon Diamond, you must go to Route 208, where there is also a Berry Master that gives you Berries, daily. You can also receive a Poketch App from the Little Girl in the house. Along with the two Trainers in that Route, William and Hannah, there is a man with a red-coloured headband, who looks like the Karate Trainers. If you go talk to him, he will give you the Odd Keystone, which you can use to help you get the Pokemon Spiritomb if you restore the tower on Route 209.
you get a spirttomb by talking to people underground 32 times. P.S this will take a long time
The Odd Keystone is given to you by a man on route 208
