Check the locking pump module under the trunk floorboard for any water intrusion.

Yes, it will. It is wrapped in a foam box and looks like :

That is the location of the siren, the security module is incorporated in the pump that operates the locks.
When it gets wet it goes haywire, I guess it can go haywire for other reasons as well though. Unless you are lucky they can get pricey.

Before doing this though see if there is actually any dampness in the trunk well where the pump sits.
