    Maybe a short in the alarm? Connections? Also the sensors in the doors, boot and bonnet?

    It'll be the siren module. They have a backup battery inside and this eventually refuses to hold charge either through age or corrosion. The alarm goes off as it thinks someone is tampering with the power supply.
    It's a sealed unit so you have to replace the whole thing or do a bit of DIY on the plastic housing.
