Could be, the alarm "function test" can be utilized to set your diagnostic compass, is it a door lock or is it something that requires more investigating. What I have seen happen on occasion is that door tumblers get replaced without realizing the difference between left/right. If the right side tumbler is installed on the left side of the vehicle then the alarm will "arm/disarm" opposite of the intended design. What remains in question is what affect will it have on the comfort system? Will the windows go up when they should be going down? I have yet to look at the wiring diagram so I am uncertain at this moment to know how it would react to a reversed signal.

Alarm function test: Two front windows down, lock the vehicle from one of the three points but do not hold the key. Give it about 30 seconds, reach in through the open window, unlock the car than open the door. The alarm should activate and than you should be able to disarm the alarm from any of the points that are being tested.
