Dead Coin Battery

The most frequent reason why the 500 key fob won't function is a dead battery. Modern key fobs offer only a limited range of operation and must be within only a few inches from the vehicle to work. If you are far from your vehicle and you press the key fob button the car won't respond and will display an "Key Fob Not Detected" message in the instrument cluster.

If this happens, replace the battery on your coin cell (Part number CR2032) with a fresh one from a reputable brand such as Panasonic, Duracell, or Energizer. They are usually available at your local hardware store or online.

You can test the coin-cell battery by pressing the buttons while standing close to your Fiat 500. The car should blink its parking lights and the key fob should work the lock and unlock buttons.

If your key fob isn't working after replacing the battery, there could be water damage that prevents it from connecting to the module in your vehicle. Water damage can occur in a variety of ways, such as simply splashing or submerging the key fob saltwater at the beach. If you suspect that your fob has been exposed to water, put it in a dry rice bag to draw the moisture back out. If this isn't working, you'll require your fob to be reprogrammed either by an auto locksmith or a dealer.

Water Damage

The fob does have rubber seals to keep water from the electronic chip inside the device, submerging it into the ocean or washing it in a machine can cause water damage. Saltwater can cause the circuit board to short and then end up dying. It's not the best idea to get the fob wet however, don't give it up when you accidentally drop it in water or fail to take it out of your pants pocket.

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 see if it is working. If the fob doesn't work, it might need to be changed. This is usually done by an auto locksmith or dealer.

If the key is newer and was not programmed to your vehicle It is likely that it needs to be replaced completely. This is a simple process that can be carried out by a professional automotive locksmith. The locksmith will require the key to be cut to match the car's ignition. The locksmith will also have to reprogram the fob into the vehicle's system. It's a simple and cost-effective procedure that can usually be completed within the same day.

Receiver Module Issues

One of the most common reasons why your 500 key fob may stop working is that it's simply out of range. The remote has a range of 30 feet, which means in the event that you are far away from your vehicle it won't be able to respond to your commands. This can be fixed by moving closer to your vehicle until it starts responding.

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

It could be necessary to replace the metal clips that hold the coin batteries in their place. If they lose tension they could stop the coin battery from sitting properly, and this will cause the remote to malfunction.

In rare cases the fob might become desync'd with your vehicle due to software issues 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 cases they might need to reinstall the program 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 the signal due to interference. This could occur if the keyfob's location is in close proximity to a radio transmitter like a cellphone 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 has suddenly stopped working, in the middle of the night and you've tried every option at home to solve it e.g. replacing batteries, reprogramming or using the spare key fob, you might 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 them into electronic commands that the vehicle interprets.

There's a quick and easy way to reset the 500's onboard system including the keyfob. Disconnect the battery for 15 minutes by removing first the negative cable and then the positive cable. Then, reconnect the battery. This will remove any remaining electric current, and also restart the car's computer. This could help you get your key fob to work again. If the problem persists you should speak with a certified technician. They can determine the exact cause of your issue.
