Dead Coin Battery
The most frequent reason that your 500 key fob doesn't work is an inactive battery. Modern key fobs operate with a limited operating range, and must be within only a few feet from the vehicle to function. If you're far from your car and hit the keyfob, it will not respond, and display the message "Key Fob Not Detected".
If this happens, replace the battery of your coin cell (Part number CR2032) with a brand new one from a trusted brand like Panasonic, Duracell, or Energizer. You can typically find them 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 near your Fiat 500 and pressing the buttons. The car will blink its parking lights, and the key fob should operate the lock and unlock buttons.
If the fob's remote doesn't work after replacing the battery, it could be damaged by water, which prevents it from communicating with the receiver module inside your vehicle. Water damage can occur in a variety of ways, ranging from the slightest splash to submerging your fob in salt water at the beach. If you suspect that your fob has been exposed to water, put 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 dealer.
Water Damage
While the fob comes with rubber seals to keep water out of the electronic chip inside the device, submerging it into the ocean or washing it in a machine can cause water damage. Saltwater can cause the circuit board to short and eventually die. Getting the fob wet is not a good idea but if you drop it in the water in a cup or fail to take it out of your pocket before you run the washing machine do not give up hope.
Remove the battery first. Before replacing G28 Car Keys , clean the electronic chip with isopropyl or another similar product. Then check the fob to check if it functions. If the key doesn't work, it may need to be changed. This is usually done by an auto locksmith or dealer.

Receiver Module Issues
The 500 key fob you have may not work because it's out of range. The remote's range is of 30 feet, which means when you're too far away from your vehicle it will not respond to your commands. It is possible to solve this problem by moving the remote closer to your car until it responds.
If your fob doesn't work after replacing the battery for the coin, also known as a "button", "watch" or "button" it could be a problem with the circuit board inside. In most cases, reprogramming the fob can resolve the problem. You can find the steps for most vehicles on YouTube or in the owner's guide.
You may have to replace the metal retaining clips that hold the coin battery. If they loose tension it can prevent the coin battery from sitting properly and could cause your remote to malfunction.
In rare cases the fob could be out of the vehicle's sync because of hardware or software problems. This can cause a major headache, but you can often fix this by visiting an auto locksmith to have them reprogram your fob for you. In some cases it is possible that the software will require reinstallation to your body control modules.
Interference
Interference can also cause the key fob to not receive or transmit signals. This is possible when the key fob is near the radio transmitter (cell phones or radar detectors) or any other source of electromagnetic radiation. Other reasons the key fob might not work include a poor connection to the buttons, damage to the internal chip or water damage.
If your key fob suddenly stopped working, or you've tried everything at home to fix it (e.g. replacing batteries, reprogramming or using the spare key fob, you may have a malfunctioning receiver module on your 500. The receiver module is located under the dash and receives the radio frequency signals from the key fob. It converts the signals into electronic commands, which are then interpreted by the vehicle.
Fortunately, there's an easy method of resetting all of the onboard systems in your 500 device, including the key fob. Disconnect the battery for 15 minutes by removing first the negative cable and then the positive cable. Reconnect the battery. This will clear out any residual electricity and restart the car's computers. This can help the key fob to function again. If the issue persists you should speak with an expert certified technician. They will be able to identify the root cause of any issues.
