Dead Coin Battery

A dead battery is the most common reason for your 500 key fob not functioning. Modern key fobs offer a limited range of operation and must be within a few inches of your vehicle to function. If you're far from your vehicle, and you press the key fob button the car won't be able to 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 new one from a reliable brand such as Panasonic, Duracell, or Energizer. You can find them at your local hardware store or online.

You can test the battery of your coin-cell by pressing the buttons while standing near your Fiat 500. The parking lights should blink and the key fob should operate the lock and unlock switches.

If your fob's key isn't working even after replacing the battery, there might be water damage that hinders it from interacting with the module inside your vehicle. Water damage can happen in a number of ways, from small splashes to submerging your fob in 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, you will need to have the fob changed by an auto locksmith or dealer.

Water Damage

While the fob has some rubber seals that keep water from the electronic chip inside it, submerging it in the ocean or washing it in a machine can cause water damage. Saltwater can cause the circuit board to short, and eventually die. In the event that you let your fob get wet, it's not an option but if you accidentally drop it in an empty cup of water, or fail to take it out of your pocket before you run the washer do not give up hope.

First take the battery off the fob. Before replacing the battery, clean the electronic chip with isopropyl, or a similar product. Test the fob next to verify if it's working. If the key does not function then it might need to be changed. This is typically handled by a dealer or professional auto locksmith.

If the key is newer and has not been programmed to your vehicle It will most likely need to be replaced completely. This is a straightforward process which can be accomplished by a professional locksmith for automotive use. The locksmith needs to cut the key to match the ignition of your car. They will also need to reprogram the fob to the system of your car. This is a cheap and quick process that could be completed on the same day.

Receiver Module Issues

Your 500 key fob might stop working because it is out of range. The remote typically has a range of 30 feet or less and if it's far from your vehicle, it won't respond to your commands. It is possible to solve this problem by moving the remote closer to your car until it responds.

If you've replaced the battery in your coin (commonly called"button" or "button" or "watch") and your fob still won't work, it could have an internal circuit board issue. In the majority of cases, reprogramming your fob will solve the problem. You can find the procedure for the majority of vehicles on YouTube or in the owner's manual.

You may have to replace the metal retaining clips that keep the battery of your coin in place. If they loose tension it could prevent the battery from sitting properly and could cause your remote to malfunction.

In rare instances it is possible that the fob will become disconnected from your vehicle due to software or hardware issues. It is possible to fix this issue by visiting your local auto-locksmith or dealer to reprogram your key fob. In some instances it may be necessary to install the software again in your body control module, as well.

Interference

Interference can also cause the key fob to not be able to receive or transmit signals. This could occur if the keyfob's location is in close proximity to a radio transmitter like a cell phone or radar detector. Other reasons the key fob might not function include a weak connection to the buttons or the internal chip, or water damage.

If the key fob has failed to work one day without notice or after trying every option at home to resolve it e.g. You could have a malfunctioning 500 receiver module after you've tried replacing the battery, reprogramming it, or using an alternative key fob. The receiver module is located under the dash, and it picks up the radio frequency signals from the key fob. It converts them to electronic commands that the vehicle interprets.

Luckily, there is an easy way to reset all of the onboard systems in your 500, including the key fob. Disconnect the battery for 15 minutes, removing first the negative cable, then the positive cable. Then, reconnect the battery. This will remove any remaining electrical charge, and then restart the computer of your car. This will help you get your key fob to function again. If the issue persists, you should seek out an expert technician. They will be able to determine the exact cause of your problems.
