One of the main reasons for a car's key button to stop working is that the switch inside has worn out. Excessive use and exposure to elements are the primary reasons. The switch is made of an extremely hard plastic with many switches on its surface. Each switch is responsible for activating the specific function you are using the key for. As the switch ages, it becomes more difficult to activate these functions. You will have to apply more pressure to the switch in order to get it to work. This can further damage the switch and decrease its lifespan.

When you use the keypad, they are continuously exposed to moisture and dust. Eventually, they will become worn to the point that they are no longer in contact with the circuit board or the sensor beneath the keypad.

You can attempt to get the key fob replaced at an auto dealer, but this can be expensive and could take an extended time. You can also call an emergency locksmith who will fix your key fob at less.
