Anyone have advice on how to solder this puppy back on? It's for the "O" in "LOCK" and it's behind a huge mass of wires (what isn't in the Hobbit). I can hardly get in there and push it in place. Assuming I do find a way to hold it in place, I worry that if I go in with a soldering iron and slip it will melt half the wiring in the machine in the process. Suggestions?
