was getting random "front passenger door open" warnings over the past few months even though we repeatedly opened/closed the door. got the expected behavior as if it really weren't properly closed like doors won't lock as i drove off, short honk when i try to arm the alarm, interior lights stay on, etc. it would eventually go away with an engine cycle here and there. but just this morning though i was able to lock the doors from the remote as normal without incident, someone at the office just told me my alarm is sounding off so i'm guessing it's the same front passenger door sensor. anyone replace theirs? i'm assuming it's a simple DIY - pop door card off, unplug something, remove & replace?
