I am assuming that the Alarm is going off after you have unlocked the vehicle.  You could try unlocking the vehicle with the Key Blade to see if that will deactivate the Alarm.

If the Alarm is going off when the vehicle is locked and the Alarm set then potentially this could be caused by the Interior Motion Sensors.  These can usually be deactivated by a button in the vehicle or a setting on the Combination Meter.  This will eliminate the sensors as being the issue.  If the Alarm still goes off then there must ba another issue.

The only other potential Issue is the Alarm Module / Siren itself. The only option here would be to replace the Module.

A full diagnostic code read should be carried out and the data relating to all door sensors should be checked including the bonnet sensor.
