C4 grand Picasso 2015 alarm

Hello! Can anybody give me an idea where the alarm module is located on the 2015 grand Picasso? Mine goes off when trying to lock the car. Have used diagnostics on it and it is saying the alarm battery is dead. Any help appreciated!

The alarm siren is the part that contains the battery and when this fails, it's the same as breaking the circuit and setting the alarm off.

The siren module is located under the front scuttle left side, so the trim has to come off to get to that:

Many thanks for the quick reply!
