Problems:
1) to get it stick on the key
2) to not rub some off between the fingers of the PCB...


Probably easiest is to get a old TV remote or such, and rip off the keyboard.
Then nip off the condictive pads using a very good end nipper.
Do the same on the keyboard you repair.
Tne glue the good pads in place using a good rubber glue.
There is one called Alusol (i think) that is for repairing boots.
Very durable, though, and a bit flexible.

Another idea is to get the metal disc from a keuborad that use the technology of a bent disc that "clicks" down at the PCB when pushed.

As this all takes time, I once did a "repair" by adding a row of normal panel mount pushbuttons outside the original keyboard.
