Hotswap PCB Soldering

[Phillius_Maximus]

Hi guys!

I am brand new to the ol' keyboard world so bear with me haha
I've just bought a Luminkey80 and think I might have internally dislodged(?) one of the sockets. The right Ctrl key was working fine and then not. The actual kailh socket is still attached to the board but no longer functions via pins or the underside with tweezers.
I have seen that soldering can help fix the issue. Would reheating the solder on the socket do the trick or would I need to add a couple of bridging wires?

If the bridging wires are the go, is the go, I just wanted to confirm that this would be the way to go about it. The two ends connected by the red line seem to activate the left arrow and the green connecting line activates the Shift key. Would wiring it like this give life back to my Ctrl key?



Cheers!

do you have a multimeter with decent tips available? i would measure the resistance between the socket and the pins (look at the value and don't use the beeping!). always easiest to fix something if you know what the problem is. you should be able to follow the traces and vias to determine the mcu pins your socket is connected to.
otherwise i would start by just reheating the solder on the socket with some flux paste if you have any, otherwise apply a little bit of new solder, as there is (usually) flux in the solder. you can try to remove some of the solder beforehands if you want a prettier solder point.
