Troubleshooting

The key fob is equipped with an electronic chip which communicates with your Fiat's immobiliser system to ensure that only authorised vehicles can start the engine. If the transponder chip in your key fob is damaged, it won't be able to connect to the immobiliser unit which means that your car will refuse to start.

The good news is that it's possible to repair a broken key fob, provided the chip is not physically damaged. A professional locksmith will utilize standard techniques used by dealers to repair the chip quickly.

It is possible to utilize an OBD scanner to see whether your fob is communicating with the receiver module. It's a quick and simple process that could provide a first indication of the problem.

Water Damage

The key fob isn't waterproof even though it is fitted with rubber seals that prevent water from getting inside the electronic chip. The key fob should be able to handle water from a shower or water from a wash cycle, however, submerging it into pools or ocean waters is not recommended.

If the key fob is exposed to water and fails to function the device will need to be reprogrammed. This process can be done using the instructions found in your owner's manual or by bringing it to a professional auto locksmith or a Fiat dealer.
