Your horn does NOT honk or beep when the alarm is set or goes off. Only the new replacement sirens 'chirp' when arming/disarming. The siren has a set of wafer rechargeable batteries in them that will eventually go bad and start acting up. Order the 'chirping' siren and no more than a reasonable amount of time to replace it will get you a new siren and chirp when you lock/unlock. BUT, if it is water in the 'trunk' central locking module, it is going to be a lot more expensive and troublesome to get in there and fix it. It's possible just time consuming and expensive for the parts. Like was recommended, look for the water in the 'trunk' first by getting under the rear and poking a hole in the two rubber plugs just rearwards of the axle at the bottom of the 'trunk' and see if water comes running out of either side. You also may be able to grab/pop the passenger side out if you do not want to poke a hole in it. If there is no water in there, then I would definitely replace the siren. Thats the best advice I have in this instance.
