Answer
Keith-

 Legally, you can't.  I'm not sure how laws work in Canada (or wherever it is your from...I assume it's outside the US since you measured mileage in km's), but it's very illegal to commit odometer fraud here. A certified shop can do it, but that's about the only way to have it done legally.  Hope this helps.
