This is the only part in the face removal I would suggest using the metal spudger as you'll need a little more leverage to release the adhesive holding the faceplate down.

Insert the metal spudger in the area located but only as far as you need to get some leverage to pry the faceplate up. Work cautiously and slowly as this can easily damage components.

The adhesive is located in two places and because this doesn't seal the device together for IP-67/68 requirements, it isn't necessary to replace.
