Dead Coin Battery

The most common reason your Fiat 500 key fob will not lock or unlock the doors is due to a dead battery.

With a small flathead screwdriver, pull the retaining clip open to remove the battery and replace it with a new one. Use a battery that has the same size, voltage and specifications as the original.

The key fob could also be damaged or corroded through exposure to water. Even a quick bath in warm, soapy water can cause damage to the chip. Make sure your key fob is dry.

Water Damage

Faulty Receiver Module

There are several reasons why the fob may stop working. These include a dead coin battery or water damage, worn buttons or a problem with the receiver module, and signal interference or an electronic chip that has failed.

If the fob was in a pocket that has suffered a severe trauma, like being dropped on hard floors or being washed in a washing machine or dishwasher, it might not be able to communicate with the car's Body Control Module (BCM).
