I have an old car key and the rubber buttons that push the micro switches have come off.
How can I fix this to make the car key usable if I still have the rubber buttons? What about if I don't still have the rubber buttons? I don't want to spend lots of money as the car is old and might not last long.
UPDATE: So while my original question specifically related to micro-switches upon reading the hack on the Sugru site how would the key be fixed if the "small rod that touches the chip" was missing?
