1996 buick regal remote programing

An "ultra start" remote starting system was installed on my regal as an aftermarket item. Currently when I attempt to unlock/lock my car with the ultra start remote. The car chimes twice and the interior lights flash. But the doors do not unlock. I am able to use the standard keyless remote that came with the regal to unlock the doors. I tried the programing for the 1997 to 2000 but nothing happened when I got to step three. I have a 1996 buick regal custom sedan with a TRW three button buick remote. I have searched this forums high and low for 1996 regal programing info and I have found everything else except that. thanks for any help.

Well I emailed the local buick dealer just to see how much money they would want to take care of this for me. He sent me to the installer of the remote starter instead, saying that he couldnt do it.Any way I guess it off to the local stero shop to see what they can do as the install place is 400 kms away.
