You can even look through they keyway and se how far down the pins go, the bump key must not raise any pins when it is fully inserted. you can also ask your local locksmith how deep the nr 9 cut is on the trioving lock, (if you live in norway, which I assume you do). Also read the toool.nl/bumping.pdf before you proceed.
Here are some charts for finding out the cut depths on some common cylinders.
In case you want to make other bump keys.
