Replacing the key fob battery on the Fiat 500 is straightforward and cost-effective. It takes around 10 days for the key to be delivered from the Fiat main dealer.
Diagnosis of a Fault
The key fob contains an electronic chip that communicates with the Fiat immobiliser system. This guarantees that only authorized vehicles can start the vehicle. If the transponder chip in the key fob is damaged, it won't be able to connect to the immobiliser unit, and as a result, your car won't start.
The good news is that it's possible to repair a broken key fob, as long as the chip isn't physically damaged. Locksmiths who are professionals will use standard techniques used by dealers to repair it quickly.
It's possible to use an OBD scanner to check whether your fob is communicating with the receiver module. This is a simple process that can give an initial indication of the source of the issue. If the OBD scanner says there is no communication between the receiver and transmitter modules, it may be required for the fob's transmitter module to be replaced. This is a costly option and should be left to locksmiths.
Dead Coin Battery

Water Damage
Although the key fob comes with rubber seals that keep water from the electronic chip inside, it's not waterproof. The key fob will likely be fine in the event of the splash of rain or water from a washing cycle, however, submerging it in water from the ocean or pool is not recommended.

This is the perfect time to think about buying a new key fob if yours is beginning to appear worn and damaged.
