You have to have a side panel off usually to reach in to press on one the face plate tabs. A
light pressure at first there is used to avoid breaking the preformed plastic retaining clips. It
does seem to become second nature after a few times doing changes like this. But the word
of caution for first timers is not to force anything. Take your time and do things one step at
a time to see good results. After a few times you will be swapping hardwares for friends!
