Dead Coin Battery
The most frequent reason that your Fiat 500 key fob will not unlock or lock the doors is a dead battery. The key fob comes with the battery of a coin-cell that will drain quickly in the event that it is not utilized frequently enough. If your remote is beginning to show signs like a loss of range or stopped working, then the battery may be dead.
The battery inside the key fob is held in place by metal retaining clips. If the clips aren't secure, it could lead to contact issues that will stop your remote from receiving power. Utilizing a small screwdriver, pull the retaining clip outwards to take out the battery, and replace it with a brand new one. Make sure that the battery you choose to use has the same voltage, size, and specifications as the original.
The exposure to water can cause the key fob to corrode, or even become damaged. Even a short bath in warm, soapy water could damage the chip. Keep your key fob dry.
Water Damage
If your key fob isn't working properly, it could be caused by water damage. Key fobs come with rubber seals that protect them from being damaged by rain or splashes of water, but it is crucial to keep your car keys from being tossed into the pool, ocean and washing machine!
The key fob is equipped with an electronic chip that transmits a signal car's immobilizer system. This is the reason why your 500 can start or lock, however when the chip becomes wet, it will no longer work.

If your key fob stops working after exposure to clean water from the tap or rain, unplug the battery and wipe down the electronic component using a paper towel to ensure it's dry before putting it back into. If the key fob will not work, there's an opportunity that it is a fried component and needs to be replaced.

Faulty Receiver Module

Fiat key fobs transmit a signal to the vehicle that will unlock and close doors (and start the car for those with an automatic transmission) up to 50 feet. However there are a few things that could cause the fob to cease working. It could be due to a dead battery damaged by water buttons, worn ones as well as a receiver module problem and signal interference or an electronic chip malfunctioning.
If the fob is stored in a place that has been subject to extreme trauma, such as being dropped on hard floors or getting washed in a wash machine or dishwasher, it might not be able to communicate with the car's Body Control Module (BCM). The BCM is a security system that can only accept signals from genuine original keys.
If this is the case, you will need to replace your fob. G28 Car Keys can take care of all aspects of the key replacement procedure, including programming a new one for your 500. They can even provide the fob cloned to work exactly the same way as the original (and costs only one-third of the price).
