I used a small flathead screwdriver, but it would be better to use a plastic scribe if available.

Insert tool between faceplate and case.

Gently pry up.

Slide tool all the way around, gently prying up as you do.

If you break off a little tab, that's ok. Just try not to break off too many :)

This step is really optional, but it gives you an opportunity to clean under the faceplate and makes it easier to handle in the next step.
