Out Of Control!!
The central locking\anti theft system is complicated--in your case you could have one or more sensor\switch faults(there are 15) all the way up to a faulty PSE unit which in your case controls when the siren is sounded--if you want to do it correctly find someone who has the DAS\HHT diagnostic system and have them run a quick test---FYI,all the "B" central locking and anti theft faults can not be read by a handy dandy scanner.

First, lift your rear seat and check for water.
I had a similar issue three years ago, there was water from a cracked AC drain hose on the entire passenger side of the vehicle. Vacuumed all the water, dried everything, cleaned the central locking unit with electronic parts cleaner and reinstalled, no more issues.
It's worth a look.
