Dead Coin Battery

The most common reason the 500 key fob won't function is due to a dead battery. Modern key fobs have a limited range of operation and must be within just a few inches of the vehicle in order to function. If you're 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 occurs you need to replace the battery of your coin-cell (Part Number CR2032) by a brand new one of a reputable brand like Panasonic Duracell or Energizer. They can be found in your local hardware store, or on the internet.

After you've changed the battery on the coin cell you can test it by standing in front of your Fiat 500 and pressing the buttons. The parking lights will flash and the key fob should operate the lock and unlock switches.

If the fob's remote doesn't function after replacing the battery, it might be damaged by water that blocks it from connecting to the receiver module in 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 that your fob has been exposed to water, place it in a bag of rice to draw out the moisture. If that doesn't work, your fob will probably require reprogramming by an experienced auto locksmith or the dealer.

Water Damage

Water damage can occur when you immerse the fob in the ocean or wash it in a washing machine. Saltwater can cause the circuit board to short and eventually cease to function. Getting the fob wet is not an option but if you drop it into a glass of water or don't remember to remove it from your pants pocket before running the washer do not give up hope.

First remove the battery from the fob. Before replacing the battery clean the electronic chip using isopropyl, or a similar product. Check the fob to check if it's functioning. If the key doesn't function, it may have to be reset. This is usually handled by a dealer or professional auto locksmith.

If the key is a newer model and was not programmed to your car It is likely that it needs to be replaced completely. A professional locksmith in the automotive industry will be able to complete this process. The locksmith will need the key cut to match the car's ignition. They will also need to reprogram the fob to your vehicle's system. This is a quick and inexpensive process that can be completed the same day.

Receiver Module Issues

The 500 key fob you have may not function because it's out of range. The remote has a range of 30 feet. So when you're too far from your car it won't be able to respond to your commands. This can be easily fixed by moving closer to your vehicle until it begins responding.

If you've replaced the coin battery (commonly called a "button" or "watch") and the fob won't work, it could have an internal circuit board problem. In most cases, reprogramming the fob can resolve the problem. The instructions are available for most vehicles on YouTube or in the owner's guide.

It could be necessary to replace the clips made of metal that hold the coin batteries in place. If they lose tension, it can prevent your coin battery from sitting properly, causing your remote to malfunction.


In rare cases the fob could be desync'd with your vehicle due to software issues or hardware issues. This can cause a major trouble, but you could usually fix it by visiting a local dealer or auto locksmith to reprogram your fob for you. In some cases they may have to reinstall the software in your body control module, too.

Interference

In addition to a dead battery on a coin the key fob could not be able to transmit or receive an signal due to interference. This could happen when the keyfob's location is in close proximity to a radio transmitter like a cell phone or radar detector. Other reasons the key fob could not function include a weak connection to the buttons and internal chip or water damage.

If the key fob has been unable to function for a while without notice, or after trying everything you can do at home to solve it e.g. replacing the battery, reprogramming, and using the spare key fob, it could 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. emergency converts them to electronic commands that the vehicle interprets.

There is a simple way to reset the 500's internal system including the keyfob. Disconnect the battery for 15 minutes by taking off first the negative cable, then the positive cable. Reconnect the battery. This will clear any residual electrical charge, and then restart the car's computer. This can help get your key fob to work again. If the problem persists you should speak with a certified technician. They will be able to determine the exact cause of your issue.
