Dead Coin Battery

The most common reason your 500 key fob doesn't work is the battery is dead. Modern key fobs offer limited operating range and must be within just a few inches of 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 a "Key Fob Not Detected" message in the instrument cluster.

If this occurs then replace the battery for your coin-cell (Part Number CR2032) with a new battery of a reputable brand such as Panasonic Duracell or Energizer. They are typically available in your local hardware store or online.

After you've replaced the battery of your coin cell you can test it by standing close to your Fiat 500 and pressing the buttons. The car should blink its parking lights and the key fob will operate the lock and unlock switches.

If your key fob still does not work after replacing the battery, there might be water damage that prevents it from communicating with the module inside your vehicle. Water damage can happen in many ways, including a simple splash or submerging the key fob in saltwater at the beach. If you suspect that your fob has been exposed to water, place it in a bag of rice to draw out the moisture. If this doesn't work the fob might need to be reprogrammed by an experienced auto locksmith or the dealer.

Water Damage

The fob does have rubber seals to keep water from the electronic chip inside and out of the ocean or washing it in a machine can cause water damage. Saltwater is especially dangerous to the circuit board of the fob and can cause it to short out and eventually end up dying. It's not a good idea to let the fob get wet but don't give up if you accidentally drop it in water or fail to remove it from your pants pocket.

First take the battery off the fob. Before replacing the battery, clean the electronic chip with isopropyl, or a similar product. Then try the fob and see if it works. If the fob doesn't work, it may need to be programmed again. This is usually done by an auto locksmith or repairer dealer.

If the key is more recent and has not been programmed to your vehicle It is likely that it needs to be replaced completely. A professional locksmith for automotive will be able to complete this process. The locksmith needs to cut the key to match the ignition on your vehicle. The locksmith will also have to reprogram the fob into the car's system. This is a quick and inexpensive process that can usually be completed in the same day.

Receiver Module Issues

One of the main reasons why your 500 key fob won't be working is because it's out of range. The remote typically has a range of 30 feet or less, and if it's too far from your car, it will not respond to your commands. It can be solved by moving closer to your vehicle until it begins responding.

If your fob doesn't work after you replace the coin battery, also called a "button", "watch" or "button" it may be due to a malfunction on the internal circuit board. In the majority of cases, reprogramming your fob will solve the problem. You can find the instructions for the majority of vehicles on YouTube or in the owner's guide.

It is possible to replace the metal retaining clips that keep the coin battery. If they lose tension, it can prevent the battery from being properly seated and result in the malfunction of your remote.

In rare cases the fob might be out of connection with your vehicle as a result of hardware or software issues. This can be a major issue, but you are able to usually fix it by visiting an auto locksmith to reprogram your fob for you. In some instances it may be necessary to reinstall the software on your body control module as well.

Interference

Interference can also cause the key fob to not receive or transmit the signal. This can happen when the key fob is located near radio transmitters (cell phones or radar detectors) or any other source of electromagnetic radiation. The key fob might not function due to a poor connection to the buttons or water damage, or damage to the internal chips.

If the key fob has suddenly stopped working, suddenly, or after trying everything you can do at home to resolve it e.g. replacing the battery, reprogramming, and using the spare key fob, you might have a faulty receiver module on your 500. The receiver module is situated under the dash and receives the radio frequency signals from the key fob. It transforms the signals into electronic commands which are then interpreted by the vehicle.

Luckily, there is an easy method to reset all of the onboard systems in your 500 and include 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 electricity and then restart the car's computers. This could help get your key fob working again. If the problem persists you should seek out an expert technician. They can identify the exact cause of issues.
