Just find a good locksmith, they can usually do it and it's much cheaper. I had the same problem last year and Acura wanted to replace my whole imobilizer unit because I didn't have the red key. Would of been around $1000 for the job. For $35 a local locksmith copied my keys and made sure it worked. When I went back to buy some MTF from the local Acura, they asked me if I still wanted the $1000 job so I could get another key. The manager even offered to get a discount. Told him I got one copied for $35. Should of seen the look on the manager's face.
