Dead Coin Battery
A dead battery is the main cause of your 500 key fob not working. Modern key fobs operate with a limited operating range and should be within a few feet of the car to operate. If you're not close to your vehicle and you 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, simply replace the coin cell battery (Part number CR2032) by a new one from a reliable brand like Panasonic, Duracell, or Energizer. They are available at your local hardware store or online.
After you've changed the battery on the coin cell It is possible to test it by standing in front of your Fiat 500 and pressing the buttons. The car should flash its parking lights and the key fob should operate the lock and unlock buttons.
If fiat car key isn't working even after replacing the battery, there may be water damage that hinders it from communicating with the module inside your vehicle. Water damage can happen in many ways, including the simple splash or submerging your key fob in saltwater at the beach. If you suspect that your fob was exposed to water, you can place it in a bag of rice to draw out the moisture. If this isn't working, you'll need to have the fob reprogrammed either by an auto locksmith or dealer.
Water Damage
Damage to the water supply can occur if you immerse the fob into the ocean or wash it in a washing machine. Saltwater can cause the circuit board to become shorted and eventually end up dying. It's not a good idea to submerge the fob in water however, don't give it up if you accidentally drop it in water or forget to remove it from your pocket.
Take the battery off first. Clean the electronic chip using isopropyl ethanol or a similar product and then dry it completely before replacing the battery. Check the fob again to verify if it's working. If the key isn't working, it may have to be programmed again. This is usually done by a professional or dealer auto locksmith.

This is a simple process that can be carried out by a professional locksmith for automotive use. The locksmith will need to cut the key to match the ignition in your vehicle. The locksmith will also have to reprogram the fob into the vehicle's system. This is a quick and cost-effective procedure that can be completed on the same day.
Receiver Module Issues
One of the most common reasons your 500 key fob might stop working is that it's simply out of range. The remote usually has a range of 30 feet or less, and if it's too far away from your car it won't respond to your commands. You can easily fix this by moving the remote closer to your car until it responds.
If you've replaced the coin battery (commonly known as"button" or "button" or "watch") and your fob still won't work It could be because of an internal circuit board problem. In the majority of cases, reprogramming your fob will fix the problem. You can find the steps for most vehicles on YouTube or in the owner's manual.
It is sometimes 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 and cause your remote to malfunction.
In rare instances, the fob may be out of sync with your vehicle because of hardware or software problems. You can fix this problem by visiting your local auto-locksmith or dealer to reprogram your key fob. In some cases, they may need to reinstall the software on your body control module, too.
Interference
Interference can also cause the key fob to be unable to receive or transmit an signal. 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 the key fob could not function include a weak connection to the buttons or damage to the internal chip or water damage.
If your key fob suddenly stopped working, or you've tried everything at home to resolve it (e.g. replacing the battery, reprogramming, and using the spare key fob, you may have a faulty 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. Then, it converts them into electronic commands that the vehicle interprets.
Fortunately, there's an easy way to reset all on-board systems in your 500 and include the key fob. Disconnect the battery of 12 volts for about 15 minutes by disconnecting the negative cable first then the positive cable. Reconnect the battery. This will get rid of any remaining electricity and then restart the car's computer system, which can help the key fob to function again. If the problem persists you should consult an expert technician. They can identify the exact cause of problems.
