How do I disengage the alarm system on my 2000 Volkswagen Golf GLS?

Hey there, I have a 2000 Volkswagen Golf GLS. Here is my problem: my alarm system keeps going off on its own when i start my car or when the passenger door is opened. My automatic key was stolen, and i have no way of shutting the alarm off until it stops by itself after 30 seconds. Can anyone PLEASE tell me what I can do to fix this problem or how to disengage the alarm system? I am grateful for your help.|||you have a problem with one of your door latch. The way you can figure it out is: turn the dome light on position door open, Close all door and then open the door one by one. If the dome light doesn't turn on, the latch is the problem. If the dome turns on the latch is okay. On your car the alarm is part of the body Comfort system and cannot be disengaged. I hope this will help. Replacing the latch is another problem too and I don't recommend you to do it yourself.
