Dead Coin Battery

A dead battery is the most common cause of your 500 key fob not working. Modern key fobs only have an operating range that is limited and must be within just a few inches of the vehicle in order to work. If you are far from your vehicle when you press the key fob button, the car won't respond, and will display the "Key Fob Not Detected" message in the instrument cluster.

If this happens, simply replace the coin cell battery (Part number CR2032) by a new one from a reputable brand like Panasonic, Duracell, or Energizer. You can find them at your local hardware store or online.

You can test the battery of your coin-cell by pressing the buttons while you're standing close to your fiat remote key (Suggested Internet site) 500. The car should flash its parking lights and the key fob should work the lock and unlock switches.

If your key fob isn't working even after replacing the battery, it may be water damage which hinders it from communicating with the module in your vehicle. Water damage can happen in many ways, such as the simple splash or submerging the key fob into 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 fails, you'll need to have your fob reprogrammed either by an auto locksmith or a dealer.

Water Damage

While the fob has some rubber seals that 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 be particularly harmful to the fob's circuit board and can cause it to short out and eventually end up dying. It's not good to submerge the fob in water however, but don't give it up if you accidentally drop it in water or fail to remove it from your pocket.

Take the battery off first. Clean the electronic chip with isopropyl alcohol or a similar product and dry it completely before replacing the battery. Then check the fob to check if it functions. If the key still doesn't work, it might need to be changed. This is usually handled by a dealer or professional auto locksmith.

Receiver Module Issues

One of the most common reasons your 500 key fob may stop working is that it's simply out of range. The remote typically has an operating range of 30 feet or less, and if it's too far from your car, it will not respond to your commands. You can solve this problem by moving the remote closer to your car until it responds.

If you've replaced the coin battery (commonly known as a "button" or "watch") and your fob doesn't function, it could have an internal circuit board issue. Reprogramming the fob is usually the solution to this issue. You can find directions on how to do this for the majority of vehicles by searching YouTube or reading the owner's manual.

It could be necessary to replace the metal clips that hold the coin batteries in the correct position. If they lose tension it could hinder the coin battery from sitting properly and can cause the remote to malfunction.

Interference

In addition to a dead battery on a coin the key fob could not be able to receive or transmit the signal due to interference. This could happen when the keyfob is in close proximity to a radio transmitter like a cellphone or radar detector. Other reasons why the key fob might not work may be a lack of connection to the buttons or damage to the internal chip or water damage.

If your key fob suddenly stopped working, or if you have tried everything at home to resolve it (e.g. It could be a defective 500 receiver module in the event that you've tried replacing the battery, reprogramming, or using a spare key fob. The receiver module, located beneath the dashboard, receives radio frequency signals from your key fob. It transforms the signals into electronic commands that are then translated by the vehicle.

Fortunately, there's an easy method of resetting all of the on-board systems in your 500 keys, including the key fob. Disconnect the battery 12 volt for about 15 minutes, by removing the negative cable first then the positive cable. Reconnect the battery.
