Don't hold me to this...but there are several sites on the internet that give the wiring diagram for the 2003 M45 security system. They all indicate that the security system connects to the trunk release circuit at the Body Control Module (drivers kick panel) on pin 64. It appears that this is the negative lead from the unlock circuit.
If you are a gambler, you could find that control module, find pin 64 which should have a purple wire on it...and ground that pin.
If I am right, you should then be able to just open the trunk normally.
No guarantees on this...but you can look on google for the diagrams and see if I'm right. Of course, if I'm wrong, you might just fry your alarm and or something else.
