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. The key fob comes with an internal battery called a coin cell that is prone to draining quickly when it isn't being frequently used. If your remote began to show signs of weakness such as a loss of range, and then stopped working completely it is likely that the battery is dead.

Metal clips keep the battery in place on the key fob. If the clips aren't tight, they can create problems with the contact, which can stop your remote from receiving power. Make use of a flathead screwdriver to pry open the retaining clip and remove the battery. Make sure to use a battery with the same size, voltage and specifications as the original.

The key fob might also become corroded or damaged by exposure to water. Even a short shower in soapy water can cause damage to the electronic chip inside. Keep your key fob dry.

Water Damage

Damage to your water supply could be the reason for your key fob's not functioning properly. Key fobs come with rubber seals that prevent them from being damaged by light rain or splashes of water, however it is crucial to keep your keys away from the pool, ocean, and washing machine!

The key fob contains an electronic chip that transmits an immobilizer system of your car. The chip is what allows the 500 to be locked and started. If it gets wet, however it will not function.

If you're interested in checking if your key fob is functioning it is possible to clean the internal electronics with isopropyl or electronic cleaner. It is recommended to replace the key fob when it's submerged into salt water rather than try to fix it yourself.

Faulty Chip

The chip inside the key fob connects directly with the immobiliser in your vehicle to ensure that the vehicle will start only when the proper keys are inserted. If the chip is damaged, or damaged in any way, your car will not start.

Faulty Receiver Module

Fiat key fobs transmit a signal up 50 feet away to the vehicle, which can unlock and close the doors (and start the vehicle for those with automatic transmissions). There are a few reasons why the fob may not function. It could be due to a dead battery water damage buttons, worn ones, a receiver module issue or signal interference, or an electronic chip that has failed.

If the fob is in the pocket that has been subject to extreme trauma (such as being dropped onto a hard floor or being washed in the washer) the fob might not be in a position to connect with the Body Control Module (BCM) of the car. This is because the BCM is a secure system that can only accept signals from a genuine original key and not accept any other.

If this is the case, you must replace your fob. A professional locksmith is able to handle every aspect of the replacement procedure and can even program a brand new one for the 500. They can even provide the fob cloned to work exactly like the original (and costs a fraction of the price).
