From memory it isn't a Brant, but a Sigma (M30/S32) in the 2008+ models.
This
manual was located in this

This
thread may be of some assistance, from memory a couple of the members here had the key pad activated and I believe they had to see the dealership and pay a small fee ($75 IIRC).
Pretty sure that
stimul8in (Jamie) went through this.
