Sometimes, the car alarm will sound / lights flash either by manually pressing the button on the drivers door (with key fob in pocket) or using either one of my factory key fobs unlock buttons. By pressing the fobs unlock button again or pressing the door button again, will disable the alarm and open the door. It is very annoying, and embarrassing. If I press the Lock button on the key fob, and then the Unlock button, the problem occurs less. It has happened about 60 times so far, but spread out over the year I have owned it.
