Dead Coin Battery
A dead battery is the primary reason for your Fiat 500 keyfob not locking or unlocking the doors. The battery of the coin cell inside the key fob will drain quickly in the event that you don't use frequently enough. If your remote began to show signs of weakness such as a loss of range or stopped working completely the battery could be dead.
The battery inside the key fob is held in place by steel clips that hold it in place. If the clips are loose they could cause contact issues, which could prevent the remote from receiving power. Use a flathead screwdriver to pry open the retaining clip and remove the old battery. Make sure to select an identical replacement battery kind of voltage, size, and specification as the original battery.
The key fob could also become corroded or damaged due to exposure to water. Even a small shower in soapy water can damage the electronic chip inside. Make sure your key fob is dry.

Water Damage
If your key fob isn't working correctly, it could be caused by water damage. Key fobs have rubber seals that protect them from being damaged by a light rain or a splash of water, however it is very important to keep your keys away from the ocean, pool, and washing machine!
The key fob has an electronic chip that sends an electronic message to the immobilizer of your car. This is what allows your 500 to start or lock, but when the chip becomes saturated, it won't be able to longer work.
You can clean the inside electronics of your keyfob with isopropyl Alcohol or an electronic cleaner to determine whether they're still in good condition. It is recommended to replace the key fob if it's submerged into salt water rather than attempting to repair it yourself.
A replacement fob could cost you a little bit however it's much cheaper than having to have your Fiat 500 towed to a dealership and repaired there! You can also make it yourself in just only a few steps. Make sure you have the correct battery type before attempting to open your keyfob. You can find step-bystep instructions for any car keyfob online.
Faulty Chip
The chip in the key fob communicates with the immobiliser in your car to ensure that your vehicle will start only when the right keys are in place. If the chip is damaged or destroyed the car won't start regardless of what you do.
A chip that is defective can happen due to many reasons, but the most common cause is water damage or a dead battery. It is best to delegate the work to a professional locksmith, who will be able to replace the chip quickly and at a reasonable price.
If your key fob fails to function after exposure to clean water from the tap or rain, unplug the battery and wipe down the electronic component with a tissue to ensure it is fully dry before putting it back into. If the key fob fails to work it's probably a fried chip and is required to be replaced.

Faulty Receiver Module
Fiat key fobs transmit an electrical signal to the vehicle which will unlock and close doors (and start the car for vehicles with an automatic transmission) up to 50 feet. However there are some things that can cause the fob to stop functioning. It could be due to a dead battery water damage, worn buttons, a receiver module issue or signal interference, or an electronic chip that has failed.
If the fob was placed in a pocket that suffered a severe trauma, like being dropped on hard floors or getting washed in the washing machine and it isn't capable of communicating with the car's Body Control Module (BCM). This is because the BCM is a secure system that will only accept signals from a genuine key and not any other.
