This doesn't work that way, not with this kind of old-school keyboard. With a new mechanical keyboard, you just unsolder or swap directly (hot swap they call it) the switcher of your faulty key, and there you go. Here all the keys form part of a single block. Look on internet, youtube, I'm pretty sure you'll find what I'm talking about.
Let me clarify it a little. In an old, cheap or laptop keyboard, the switching occurs between two plastic circuits (membranes), the keypad press a rubber layer in the point where touching the membranes causes the circuit to close. The model m is similar, just a buckling-spring is placed in each key socket to give a "feedback". But the thing is built as a whole, using membranes. These plastic circuits tend to erode with time, and if there is no replacement the only solution is to rework the paths. When there is only a key giving problems and you are lucky, cleaning with soapy water these plastic circuits, wiping them with extremly care and placing them back in perfect allineation, again, if you are lucky, can solve the problem. Until other key starts to fail... In a modern mechanical keyboard the switching occurs inside an independent piece call the switcher. Different colors correspond to different feedback. Nowdays these pieces aren't even soldered, just fixed by pressure. You just pull them out and push them in. So if a key doesn't work, most of the time you just have to change the switcher. And the popularity of certain models have created a quasi standard, so if you buy a keyboard following those models and your fault is more serious, you can just buy an new circuit board, or if you drop your keyboard and break its case, you can buy a replacement (frame), etc. There are a lot of options for different taste and badgets. All are advantages and live is too short, take my advice, buy you a new one. adr.
