How do you program a new key for a 318iE46

I have just paid for a new key which arrived however it is

not working.

How do you program/tune the new key to the car.

Help needed as I live in the middle of nowhere.

I think the E46 uses the same diamond key as the E39, so, if it does, the red bold link below may help:

Instructions for getting a new key to work with your car are in the cars owners manual. In my manual it's on page 145-146.
