My grandfather drives an old car for which replacement parts are hard to get. Lately his wireless key stopped working because the buttons were worn down. Luckily, one can get a replacement housing from China for a couple Euros.
The switches on the PCB were replaced as seen in the gallery below.

PCB before the button replacement. Notice the black rubber residue on the switches.
We haven't had SMD buttons laying around, therefore some THT buttons were used.
Desoldering using the hot air rework station. 300°C, 35% flow.
After the new buttons were soldered in place.
Old vs. new key.
