"Should" be easy...
I believe you turn the key to the radio position and then stick a pin up the hole next to the key, I have found hex wrenches work good on the other cars I have done (don't ask). (rant) Farking Local Stealership told me you couldn't just get the tumblers and had to replace the entire thing at the cost of about 1500 bucks... watch out for Davis Auto Group in Solon Ohio (/rant)
However... I do have some cool ass switchs to start the car now....
