Everybody a big thanks for reaching out!
I have ended up with a combination of suggestions.
1. I first applied a Boolean to cut out the hatch hole in the remotes body mesh.
2. After the Boolean I cleaned the topology.
3. I duplicated the outer edge of the cutout and separated this into a new object for modelling the hatch.
4. Then I modeled the holes and placed the screws.
5. A little bit of scaling of the hatch and placed it into the body.
6. A bit of proportional editing was needed to make a better fit.
