Well, I can tell you that the reason you have to unlock the passenger door to disable the alarm is because there's a sensor in each lock cylinder on the vehicle, and the one in the driver's door is worn out. Eventually the one in the passenger door will wear out too, and then you'll have to unlock the hatch to disarm the thing...
Anyway, on my '93 the alarm was disabled by grounding a certain wire in the driver's kick panel, but on the newer ones such as yours, I think they made it more difficult. Someone else will have to chime in here.
Have you tried a search?
P. S. BTW, I see that it's your first post. Welcome to the forum!
