The unit will come apart with some force as you pry up around the top edges with something thin and strong like the round end of a stainless steel nail file, etc...be carefull, as it will take some force. ...clean all parts that come out of phone, keypad, rubber, plastic with alcohol and old toothbrush,then soap and water and dry with cotton towel and let them sit for awhile and air dry thouroughly. good luck
