Dead Coin Battery

The most frequent reason that your 500 key fob won't function is an inactive battery. Modern key fobs have a very limited operating range and must be within some feet of the vehicle to operate. If you are far from your vehicle and press the key fob button, the car won't respond and will display a "Key Fob Not Detected" message in the instrument cluster.

If this happens, replace the battery on your coin cell (Part number CR2032) with a brand new one from a reliable brand like Panasonic, Duracell, or Energizer. They are usually available in your local hardware store, or online.

More Material can test the battery of your coin-cell by pressing the buttons while you're standing close to your Fiat 500. The parking lights should blink and the key fob should operate the lock and unlock switches.

If the key fob doesn't work after replacing the battery, it might have water damage that prevents it from communicating with the receiver module inside your car. Water damage can happen in a variety of ways, from a light splash to submerging your fob in salt water at the beach. If you suspect your fob was exposed to water, you can try placing it in a dry rice bag to pull the moisture out. If this fails, you'll have to get your fob reset by an auto locksmith or a dealer.

Water Damage

Although the fob is equipped with rubber seals to keep water from the chip's electronic circuit and out of the ocean or washing it in a machine could cause water damage. Saltwater can be particularly harmful to the fob's circuit board, causing it to short out and eventually end up dying. If you get the fob wet, it's not an ideal idea however, if you drop it into an empty cup of water, or don't remember to take it out of your pocket before you run the washing machine Don't give up hope.

First take the battery off the fob. Clean the electronic chip using isopropyl ethanol or a similar product and dry it completely before replacing the battery. Test the fob next to check if it's working. If the key doesn't work, it may need to be changed. This is usually handled by a professional or dealer auto locksmith.

If the key is newer and hasn't been programmed to your car, it will likely need to be replaced completely. This is a simple procedure that can be completed by a professional automotive locksmith. The locksmith will need the key cut to match your vehicle's ignition. The locksmith also needs to reprogram your fob into the vehicle's system. This is an affordable and quick procedure that can be completed on the same day.

Receiver Module Issues

One of the most common reasons why your 500 key fob could stop working is because it's out of range. The remote has a range of 30 feet. So if you are too far from your vehicle it won't respond to your commands. This can be easily fixed by moving it closer to your vehicle until it begins responding.

If you've replaced the battery in your coin (commonly called a "button" or "watch") and the fob isn't working it could be due to an internal circuit board problem. In the majority of cases, reprogramming your fob will solve the problem. The instructions are available for the majority of vehicles on YouTube or in the owner's guide.

It is possible to replace the metal retaining clips that hold the coin battery in place. If they lose tension it can stop your coin battery from sitting properly, causing your remote to malfunction.

In rare cases the fob might become desync'd with your vehicle due to software issues or hardware issues. You can fix this issue by visiting your local dealer or auto-locksmith to reprogram your key fob. In some cases, the software may also require reinstallation into your body control modules.

Interference

In addition to a dead coin battery, the key fob may not be receiving or transmitting the signal due to interference. This can occur when the keyfob's location is in close proximity to a radio transmitter such as a cell phone or radar detector. Other reasons why the key fob might not work include a weak connection to the buttons or the internal chip, or water damage.


If the key fob has stopped working one day in the middle of the night and you've tried every option at home to resolve it e.g. battery replacement, reprogramming and using the spare key fob, you could have a damaged receiver module on your 500. The receiver module is situated under the dash, and it picks up the radio frequency signals from the key fob. It transforms the signals into electronic commands, which are then translated by the vehicle.

There's a simple method to reset the 500's onboard system including the keyfob. Disconnect the 12 volt battery for about 15 minutes, by disconnecting the negative cable first then the positive cable. Then, reconnect the battery. This will remove any residual electricity and restart the car's computers, which can help you get your key fob working again. If the issue continues, you should seek out an expert technician. They can determine the exact cause of your issues.
