If you gently pry the old latch out, go to an electronics parts supply store ie: Dick Smith, WES Components, Speedy spares, you can purchase a latch that will do the job. The part in question is inexpensive & works.
Push closed & it is locked, push again and it releases the door
catch. As used in portable CD players.
