any tips or links to a web site would be greatly appreciated

Normally it’s quite easy. Open the tray and with 2 hands place your thumb on each end of the top of the tray and with your social fingers carefully pull the bottom of the face plate out a bit and when you hear a click pull it up it should quite easy pull off.
Over here we have a saying! If it doesn’t work use a bigger hammer.
