Diagnostics of a fault

The key fob comes with an electronic chip that communicates with the Fiat immobiliser system. This guarantees that only authorized vehicles can start the car.

Water Damage

The key fob isn't waterproof, even though it has rubber seals to keep water from getting into the electronic chip. A splash of water from rain or washing cycle is likely to be okay but submerging it fob in ocean or pool water is likely to cause damage.
