2004 bmw x5, remote start

So i have the remote start installed and works perfectly. My issue is that to disarm the fatory alarm you have to unlock the dr door at the door module. So to counter act this i hooked the lock pulse after start on my remote start module to the lock wire at the module. Well it dosen't work. I think the car turns off power to this lock module with the vehicle running. I tried even jumping it directly to ground with nothing. So then I decided to five wire the lock motor to get it to lock with still nothing. The only other thing i can think is to add an actuator to the lock rod to manually lock it. Any ideas i got nothing? The remote start is an audiovox as-9055t

The astrochart shows you need to pulse the lock wire at the center console, AND the lock wire in the door at the same time!

Diode isolate.   Unlock before start, start, then lock.
