I was able to get the dealer to plug in a new actuator (without charging me for it!) and it did not fix the problem. My "solution" is to unplug the alarm computer so that I can enter the locked vehicle without it going off.
This gremlin is still a mystery.
Did replacing the door actuators fix the problem? I am having the EXACT same issue. Dealer wants $650 to replace the driver door actuator, but do not sound convinced that will fix the alarm issue. Any information you have would be a great help!
