I have this problem before. Alarm keep ringing even after i unlock & lock again several times... At the end i saw one insect fly out from the car then problem solved    Our motion sensor is really too sensitive. Sometimes thunder will trigger the alarm too.

Last sat complained to SC. As expected, they replied "Is normal" & sensitivity cannot adjust. Even when heavy rain + thunder, few honda cars park in their compound alarm will trigger as well.  Their suggestion, disable the motion sensor everytime you leave the car..
