^^No its never gotten wet. Im pretty sure its just from leaning up against things. Like one time i leaned up against the counter and set the alarm off.

 

This happened to me for about 10 days back when I had my g35 coupe... at one point it would go off like every hour, freakin annoying. Then one day, i just unhooked the battery completely for a few mins and then reconnected and if I recall correctly, I never had the problem again...
