Dead Coin Battery
A dead battery is the most common cause of your 500 key fob not functioning. Modern key fobs have only a limited range of operation and must be within only a few inches from the vehicle in order to work. If you're far away from your vehicle and you press the key fob button the car won't be able to respond, and will display the "Key Fob Not Detected" message in the instrument cluster.
If this happens, simply replace the battery in the coin cell (Part number CR2032) with a fresh one from a reputable manufacturer such as Panasonic, Duracell, or Energizer. They are typically available in your local hardware store or on the internet.
After you've replaced the battery in the coin cell you can test it by standing close to your Fiat 500 and pressing the buttons. The parking lights should blink and the key fob will operate the lock and unlock switch.
If your fob's key isn't working after replacing the battery, there could be water damage that has prevented it from connecting to the module inside your vehicle. Water damage can happen through a variety of methods, including simply splashing or submerging the key fob into saltwater at the beach. If you suspect your fob was exposed to water, try putting it in a dry rice bag to pull the moisture out. If this does not work, you'll have to get your fob replaced by an auto locksmith or a dealer.
Water Damage
While the fob comes with rubber seals that keep water out of the electronic chip inside the device, submerging it into the ocean or washing it in a machine could cause water damage. Saltwater can cause the circuit board to become shorted and eventually end up dying. If you get the fob wet, it's not a good idea but if you drop it into a cup of water or do not remember to take it out of your pants pocket prior to running the washing machine Don't give up hope.
First remove the battery from the fob. Before replacing the battery, clean the electronic chip using isopropyl or another similar product. Check the fob again to determine if it's working. If the fob doesn't work, it may need to be reprogrammed. This is typically handled by a dealer or professional auto locksmith.

Receiver Module Issues
Your 500 key fob may stop working because it is out of range. The remote typically has a range of 30 feet or less, and if it's too far away from your car it won't respond to your commands. This can be fixed by moving closer to your vehicle until it begins responding.
If your fob isn't working after you replace the battery in the coin, also known as a "button", "watch" or "button" or "button", it could be due to an issue with the internal circuit board. Reprogramming the fob typically resolves the issue. You can find the instructions on how to do this for all automobiles by searching YouTube or checking out the owner's manual.
You may need to replace the metal clips that keep the coin battery. If they lose tension it could prevent the battery from sitting properly and could cause the remote to malfunction.

Interference

Other reasons why the key fob might not work include a weak connection to the buttons or damage to the internal chip or water damage.
If the key fob failed to work one day out of the blue and you've tried everything you can at home to solve it e.g. You could have a malfunctioning 500 receiver module If you've tried replacing it with a battery, reprogramming it, or using an alternative key fob. The receiver module, which is located beneath the dashboard, detects radio frequency signals from your key fob. It converts the signals into electronic commands, which are then interpreted by the vehicle.
