The eject works on a gear type system. When you pryed on it the gear allignment probably got off set. The only way to check it is to take it apart and close the door and check the gear allignment. Also the eject button works on a single peg with like a half arrow shape on the end. This is spring operated so check that also while you have it apart. Also I would check the gears & wheels that the tapes run through to make sure that there is no old tape wraped around them. Hope this helps you
