Removed door catch and the unthinkable happened...HELPPP

A hole in bott om you can get pinkie thru? Maybe insert a light wire (20 ga.) in top to bottom. Work it untill you gan grab it with needle nose pliers. Pull it out and bend a hook which is then worked back into threaded hole. Lift wire pulling plate back into approximate position. (Not sure about this part) but try to secure in place with strong magnet. Good luck , sounds like a tough one but with patience along with a lot of frustration most anything can be accomplished.
