- Water Damage: Submersion in water often shorts out the delicate circuit board.
- Used Buttons: Over time, the rubber or plastic contacts inside the fob can wear down, making the buttons unresponsive.

- Use a Protective Case: Silicone covers can protect the circuit board from the effect of unintentional drops.
- Avoid Extreme Temperatures: Leaving a key fob on a control panel in the summer heat can harm the internal battery and plastic housing.
- Have a Spare: The most inexpensive time to get a second key is when the very first one is still working. Losing the just key frequently needs more expensive diagnostic work and even an ECU reset.
