With my luck I would superglue the button and then it would get stuck 'on" and triggering the alarm continuously, I would much rather pop it open and remove the contact pad.
Also if you're not careful the superglue could seep into the body and might totally seal it so you can never get it open again to replace the battery!
I tried to take it apart. But it felt like I was going to break it. I could only pop off the batter cover and that felt like it was going to break.
