For the record, this process worked for me with a brand new key.

I have just coded a replacement key using the following process (given to me by my dealer over the phone):
1. Unlock the car with an original key
2. Leave the original key somewhere far away from the car, so that the car does not detect it
3. Place the new key horizontally, pointing to the printed key symbol on the steering column. Note that I found placing the key flat against the steering column did not work - I had to have the top of the key pointing towards the key symbol on the steering column and the key held horizontally.
4. Press and hold the start button (no need to press the brake). It takes a few seconds, but then the message on the speedometer display shows that remote has been found etc.
Hope that helps.
