When you come across this situation, you can handle it by yourself.
Here show how to fix the fallen keycap of the laptop keyboard. On the one hand, it’s not professional work. On the other hand, you can save some money.

And the keycap support center has a concave part of rubber of elasticity. These two parts should correspond to each other tightly and correctly. But you should be very gentle to put it to the support. The keycap back bulge corresponds to the middle of the concave part of rubber elasticity; you can feel them properly aligned. Then press the keycap, it will tightly connect with each other.

So I have to send it to the experts instead of by myself. That is dangerous. To the worst, your laptop will stop working.
