Dead Coin Battery
A dead battery is the most frequent reason for your 500 key fob not functioning. Key fobs of today have a limited range of operation and must be within a few inches of the vehicle in order to work. If you are far from your vehicle and you push the keyfob button it won't respond and display the message "Key Fob Not Detected".
If this happens, simply replace the battery of your coin cell (Part number CR2032) with a new one from a reliable brand like Panasonic, Duracell, or Energizer. They are available at your local hardware store, or online.
You can test the coin-cell battery by pressing the buttons while you're standing close to your Fiat 500. The parking lights should flash and the key fob will operate the lock and unlock switches.
If your key fob doesn't work even after replacing the battery, there might be water damage that has prevented it from interacting with the module in your vehicle. Water damage can occur in a number of ways, ranging from the slightest splash to submerging your fob in salt water at the beach. If you suspect that your fob was exposed to water, you can place it in a rice bag to draw out the moisture. If this does not work, you'll have to get your fob changed by an auto locksmith or a dealer.
Water Damage
Water damage can occur when you immerse the fob into the ocean or wash it in a washing machine. Saltwater can be particularly harmful to the circuit board of the fob, causing it to short out and eventually end up dying. It's not a good thing to get the fob wet however, don't give it up when you accidentally drop it in water or fail to remove it from your pants pocket.
First remove the battery from the fob. Before replacing the battery, clean the electronic chip with isopropyl or a similar product. Next try the fob and verify if it is working. If the key doesn't work, it may have to be programmed again. This is usually handled by a dealer or professional auto locksmith.
If your key is older and is not programmed for your vehicle it is necessary to replace it completely. A professional locksmith for cars can do this job. The locksmith will have to cut the key to match the ignition of your car. They will also need to reprogram the fob in your vehicle's system. This is a cost-effective and quick process that can be completed in the same day.
Receiver Module Issues
The 500 key fob you have may stop working because it is out of range. The remote has a maximum range of 30 feet. So should you be too far from your vehicle it will not respond to your commands. You can solve this issue by moving the remote closer to your car until it responds.
If your fob doesn't work after replacing the coin battery, also called a "button", "watch" or "button" It could be due to an issue with the internal circuit board. Reprogramming the fob is usually the solution to the issue. You can find the instructions on how to do this for the majority of vehicles by searching YouTube? or consulting the owner's manual.
It could be necessary to replace the clips made of metal that hold the coin batteries in their place. If they lose tension, it could prevent the coin battery from being seated properly and could cause your remote to malfunction.
In rare instances the fob could be desync'd with your vehicle due to software problems or hardware issues. You can fix this issue by visiting your local dealer or auto-locksmith to reprogram your key fob. In certain instances it may be necessary to install the software again in your body control module, too.
Interference

In addition to a dead battery on a coin, the key fob may not be able to receive or transmit an signal due to interference. This could occur if the key fob is located near an electronic radio transmitter (cell phones or radar detectors) or another source of electromagnetic radiation. Other reasons the key fob might not function include a poor connection to the buttons and internal chip, or water damage.
If the key fob has been unable to function for a while out of the blue, or after trying everything you can do at home to fix it e.g. You may have a faulty 500 receiver module after you've tried replacing the battery, reprogramming it, or using a spare key fob. The receiver module, which is located beneath the dashboard, detects radio frequency signals from your key fob. It converts them into electronic commands that the vehicle interprets.
Fortunately, there's an easy way to reset all on-board systems in your 500 keys, including the key fob. Disconnect the battery for 15 minutes by removing first the negative cable and then the positive cable. Then, 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 continues, you should consult an expert certified technician. https://www.g28carkeys.co.uk/fiat-car-key-replacements-near-me/ 'll be able to identify the root cause of your issue.
