John Seiffert Typically when exterior doors are made the sticking ( the molding profile around the glass) is integral with the frame on the exterior side and the molding surrounding each piece of glass on the interior is removable. The molding on the inside is called the glass bead. When the door is built the glass panes are dropped into each opening and the glass bead molding is mitered carefully, placed into the hole and hopefully shot with brads. You must be very careful when removing the bead as to not damage the surrounding frame or the molding. It helps to concentrate on pulling one piece out then the other three will be sort of easy. Care also needs to be taken so one does not confuse the pieces simce each opening will be slightly different. Mark each piece north, east etc. and number each opening. I said "hopefully shot with brads" above because if glue was used, you are screwed. I've never seen that to date though. Good luck.
