I have a security motion sensor that controls a pair of security lights. Unfortunately, the sensor has failed and I want to replace it.
For some reason, there doesn't appear to be a way to remove/uninstall or open it as there are no visible screws.
There is a seam down one side and I have inserted a flat-headed screwdriver in there to see if I can open it. Unfortunately, that just flexes the plastic. I do not want to be too rough and damage the eaves.
The brand of the sensor is Lanson (which is sold in Australia), but I was not able to find any installation instructions for it.
Here are some pictures of what it looks like:
