Lexus IS Alarm Problem..
Its the alarm siren assy in the boot, sounds like the backup battery in the unit has gone/going? you can get a new battery for it but they cost a stupid amount of money(£90) from lexus? not sure what type they are but might be able to get a cheaper variant? but the battery part number is 89724-48010, and the part number for the whole unit is 89040-53011 (£354) so might be better getting one from a breakers or just unplugging it for the time being?

Yeah, that is where the Alarm is kept.

It'll still have the alarm mate, think its just a back up if the main power fails or is cut
Try and unplug it mate, and then sit in the car lock it with the remote and then open a door to see if the horns still sound?
I've never noticed the sounder separately myself. It's the fact that your horns don't currently work that is showing up the problem with the sounder. Once you get your horns fixed then it'll probably be fine again, and it'll be up to you whether you want to fix the sounder unit as Bandit suggested. I can't imagine there will be an insurance problem.
So is this sounder a back up in case the horns fail? I can't really see the point of it if it's so quiet - unless it's really loud on the inside of the car, similar to how your house alarm will have an internal and external sounder.
I'm curious myself now, I may well take out the fuse for my horns and set my alarm off, just to see what it's like
