Dead Coin Battery

A dead battery is the most common cause of your 500 key fob being inoperative. Key fobs of today have a limited range of operation and must be within a few inches of your vehicle to function. If you're not close to your vehicle when 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 happens, simply replace the battery on your coin cell (Part number CR2032) with a new one from a reliable brand like Panasonic, Duracell, or Energizer. You can usually find them at your local hardware store or on the internet.

You can test the battery on your coin-cell by pressing the buttons while standing close to your fiat key 500. The parking lights will flash and the key fob will operate the lock and unlock switches.

If the fob's key doesn't work after replacing the battery, it may have water damage that stops it from connecting to the receiver module inside your vehicle. Water damage can happen in a variety of ways, such as simply splashing or submerging your key fob in saltwater at the beach. If you suspect that your fob has been exposed to water, you can place it in a bag of rice to draw out the moisture. If this doesn't work, you will need to have the fob reprogrammed either by an auto locksmith or a dealer.

Water Damage

While the fob has some rubber seals that keep water from the chip's electronic circuit it, submerging it in the ocean or washing it in a machine could cause water damage. Saltwater can cause the circuit board to short and eventually end up dying. The fob getting wet is not a good idea, but if you drop it in the water in a cup or forget to remove it from your pocket before you run the washing machine and you don't have a chance, don't give in.

Take the battery off first. Before replacing the battery clean the electronic chip with isopropyl, or a similar product. Check the fob again to verify if it's working. If the key still doesn't function, it may need to be reset. This is usually done by an auto locksmith or dealer.

If the key is more recent and was not programmed to your vehicle It is likely that it needs to be replaced completely. This is a straightforward process which can be accomplished by a professional automotive locksmith. The locksmith will require the key to be cut to match your car's ignition. The locksmith will also have to program your fob into the vehicle's system. It's a simple and cost-effective process which can be completed in the same day.

Receiver Module Issues

One of the simplest reasons your 500 key fob won't be working is because it's out of range. The remote has a range of 30 feet, which means should you be too far from your vehicle it will not respond to your commands. This can be fixed by moving closer to your vehicle until it begins responding.

If you've replaced the coin battery (commonly called"button" or "button" or "watch") and the fob won't work it could be due to an internal circuit board problem. Reprogramming the fob typically resolves the issue. You can find the steps for the majority of vehicles on YouTube or in the owner's guide.

It may be necessary to replace the clips made of metal that hold the coin batteries in the correct position. If they loose tension it could hinder the battery from being properly seated and cause your remote to malfunction.

In rare instances, the fob may be out of the vehicle's sync because of software or hardware problems. This can cause a major trouble, but you could frequently fix this issue by visiting an auto locksmith to have them 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 a signal due to interference. This could happen if the key fob is near radio transmitters (cell phones, radar detectors) or any other source of electromagnetic radiation. Other reasons the key fob could not function may be a lack of connection to the buttons or damage to the internal chip or water damage.

If the key fob has failed to work one day suddenly and you've tried every option at home to resolve it e.g. You may have a faulty 500 receiver module after you've tried replacing the battery, reprogramming or using an alternative key fob. The receiver module, which is located under the dashboard, detects radio frequency signals from your key fob. It converts the signals into electronic commands, which are then translated by the vehicle.

There's a simple method to reset the 500's internal system including the keyfob. Disconnect the battery for 15 minutes, removing first the negative cable, then the positive cable. Then reconnect the battery. This will get rid of any remaining electricity and restart the car's computers. This can help you get your key fob working again. If the issue persists it is recommended that you consult an expert technician. They will be able to determine the exact cause of problems.
