Mine keeps going off randomly when the car is locked and no shops are open because it's a Sunday. If I unlock the car it goes off once the doors auto lock again.

Call this a shot in the black, but what it sounds like to me is that your battery is going dead.

When the factory alarm system is armed, and detects a drop in voltage ie: door/hood/hatch opens and courtesy light turns on it sets the alarm off.

You said your car is a 2000. The average car battery lasts about five years, and after that, cells in the battery start to weaken or die. Living in regions with extreme climates, like hot summers or cold winters may also cut down battery life. When a cell weakens or dies, there's a drop in voltage across the battery. If the voltage across your battery falls below some threshold, the alarm interprets it as a forced entry, and sets the alarm off.

Bring your battery into any Auto Zone car parts store and have them test your battery. They do it free of charge.

Be warned: If you disconnect your battery, your factory stereo will have to have the security code re entered, or it'll disable itself. The radio code and information on how to re enter it should be in with your manuals. Otherwise, you may be able to contact any VW dealer and give them your car's VIN, and they can look it up for you.

You can not. it's part of the immobolizing system or comfort control module. Sounds like your drivers door lock is shot. Common problem in VW's but it wont hurt to get your battery checked because the vendor they used Exide sucks because they putted old batteries in assembly line cars so there counter life was pretty old. Good luck
