Dead Coin Battery
A dead battery is the main cause of your 500 key fob being inoperative. Modern key fobs operate with a limited range of operation, and must be within only a few feet from the vehicle in order to function. If you're far away from your vehicle when you press the key fob button the car won't respond and will display a "Key Fob Not Detected" message in the instrument cluster.
If this happens, replace the coin-cell battery (Part Number CR2032) by a fresh one of a trusted brand like Panasonic Duracell or Energizer. They are available at your local hardware store or on the internet.
You can test the battery in the coin-cell by pressing the buttons while standing near your Fiat 500. The car should blink its parking lights, and the key fob should operate the lock and unlock switches.
If your key fob still does not work after replacing the battery, it may be water damage which has prevented it from connecting to the module inside your vehicle. Water damage can happen in a variety of ways, ranging from an accidental splash to submerging the fob salt water at the beach. If you think your fob was exposed to water, place it in a rice bag to draw out the moisture. If this doesn't work your fob will probably need to be reset by a professional auto locksmith or the dealer.

First take the battery off the fob. Clean the electronic chip using isopropyl alcohol or a similar product and dry it completely before replacing the battery. Check the fob again to see if it is working. If the key isn't working, it may need to be reset. This is usually done by an auto locksmith or dealer.

Receiver Module Issues
Your 500 key fob might not function because it's out of range. The remote has a maximum range of 30 feet. Therefore, should you be too far away from your vehicle it will not respond to your commands. This can easily be resolved by moving closer to your vehicle until it starts responding.
If your fob won't work after you replace the coin battery, also called a "button", "watch" or "button" it could be due to an issue with the circuit board inside. Reprogramming the fob usually resolves this problem. You can find the procedure for most vehicles on YouTube or in the owner's manual.

You can fix this problem by visiting your local dealer or auto-locksmith to reprogram your key fob. In some cases it is possible that the software will require reinstallation in your body control modules.
Interference
Interference can also cause the key fob to not be able to receive or transmit the signal. This may happen if the keyfob is located in close proximity to a radio transmitter, such as a cell phone or radar detector. The key fob could not function because of a problem with the buttons or water damage, or damage to the internal chips.
If the key fob stopped working one day out of the blue or even after trying everything you can do at home to fix it e.g. replacing the battery, reprogramming it and using the spare key fob, it could have a malfunctioning receiver module on your 500. The receiver module is located under the dash, and it picks up the radio frequency signals from the key fob. It converts the signals into electronic commands that are then read by the vehicle.
There is a simple way to reset the 500's on-board system including the keyfob. Disconnect the battery for 15 minutes, removing first the negative cable, then the positive cable. Reconnect the battery. This will get rid of any remaining electricity and then restart the car's computers. This could help get your key fob working again. If the issue persists it is recommended that you consult an expert certified technician. They will be able to identify the exact cause of any problems.
