Help please! My “new” 2007 XKR siren is sounding randomly. I believe the unit has its own ni cad battery pack which might be failing due to age. I need to replace it soon but more importantly I need to shut it up asap as my neighbours are getting a bit bored with it, especially during the night. If someone knows where it lives and can give me some hints as to how to access it, it would be much appreciated. Especially if it prevents a lynch mob at my door!
