Dead Coin Battery

The most common reason the 500 key fob won't function is due to a dead battery. Modern key fobs operate with a limited operating range and must be within some feet of the vehicle to operate. If you're far from your car and push the keyfob button it won't respond and display the message "Key Fob Not Detected".

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

After you've replaced the coin cell battery It is possible to test it by standing next to your Fiat 500 and pressing the buttons. The parking lights should flash and the key fob will operate the lock and unlock switches.

If your key fob isn't working even after replacing the battery, it could be water damage that has prevented it from connecting to the module inside your vehicle. Water damage can occur in many ways, such as simply splashing or submerging the key fob saltwater at the beach. If you suspect your fob was exposed to water, put it in a dry rice bag to pull the moisture out. If this fails, you'll have to get your fob replaced by an auto locksmith or a dealer.

Water Damage

While the fob comes with rubber seals that keep water from the chip's electronic circuit and out of the ocean or washing it in a machine could cause water damage. Saltwater poses a particular risk to the circuit board of the fob which causes it to short out and eventually end up dying. It's not the best idea to soak the fob in water, but don't give it up when you accidentally drop it in water or forget to remove it from your pocket.

First, remove the battery. Clean the electronic chip with isopropyl alcohol or a similar product and dry it completely before replacing the battery. Check the fob to determine if it's working. If the key isn't working, it may need to be changed. This is usually done by a professional or dealer auto locksmith.

The locksmith must cut the key to match the ignition of your car. They'll also have to reprogram the fob to your car's system. This is a quick and affordable process that is usually completed on the same day.

Receiver Module Issues

The 500 key fob could not function because it's out of range. The remote typically has an operating range of 30 feet or less, and if it's too far away from your car it will not respond to your commands. This can be easily fixed by moving it closer to your vehicle until it starts responding.

If your fob does not work after you replace the coin battery, also known as a "button", "watch" or "button", it could be due to a problem with the circuit board inside. In most cases, reprogramming the fob can resolve the issue. The instructions are available for most vehicles on YouTube or in the owner's manual.

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

In rare cases the fob might become disconnected from your vehicle because of software or hardware issues. It is possible to fix this issue by visiting your local dealer or auto-locksmith to reprogram your key fob. In some instances, the software may also need to be reinstalled in your body control modules.

Interference

Interference can also cause the key fob to not be able to receive or transmit the signal. This could occur if the key fob is located near a radio transmitter (cell phones and radar detectors) or another source of electromagnetic radiation. The key fob might not function because of a weak connection to the buttons, water damage or damage to the internal chips.

If your key fob suddenly stopped working, or if you've tried everything at home to resolve it (e.g. replacing batteries, reprogramming or using the spare key fob, it could have a faulty receiver module on your 500. The receiver module, which is located beneath the dashboard, picks up radio frequency signals from your key fob. It converts the signals into electronic commands that are then translated by the vehicle.

There's a simple method to reset the 500's on-board system, including the keyfob. Disconnect the battery for 15 minutes, removing first the negative cable and then the positive cable. Then, reconnect the battery. This will remove any remaining electricity, and allow you to restart the car's computer. This can help get your key fob to work again. If the problem persists you should seek out an expert technician. They can determine the root of your issues.
