Dead Coin Battery
The most frequent reason why the 500 key fob won't work is a dead battery. Modern key fobs have a limited range of operation, and should be within a few feet of the vehicle to operate. If you're far from your vehicle and push the keyfob button it will not respond and display the message "Key Fob Not Detected".
If this happens, replace the coin-cell battery (Part Number CR2032) with a new battery of a trusted brand like Panasonic Duracell or Energizer. You can find them at your local hardware store, or online.
You can test the battery on your coin-cell by pressing the buttons while you're standing close to your Fiat 500. The parking lights will flash and the key fob should operate the lock and unlock switches.
If the key fob won't work after replacing the battery, it may be damaged by water that blocks it from connecting to the receiver module in your car. Water damage can happen in a number of ways, ranging from an accidental splash to submerging your fob in salt water at the beach. If you believe your fob was exposed to water, 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, submerging it in the ocean or washing it in a machine can cause water damage. Saltwater can cause the circuit board to become shorted and eventually die. If you get the fob wet, it's not an ideal idea but if you drop it into an empty cup of water, or don't remember to remove it from your pants pocket prior to running the washing machine, don't give up hope.
First, remove the battery from the fob. Before replacing the battery, clean the electronic chip with isopropyl, or a similar product. Then try the fob and check if it functions. If the key doesn't function, it may have to be reset. This is usually handled by a professional or dealer auto locksmith.

Receiver Module Issues
One of the most common reasons why your 500 key fob might stop working is because it's out of range. The remote's range is of 30 feet, which means should you be too far from your car it will not respond to your commands. This can be easily fixed by moving closer to your vehicle until it begins responding.
If you've replaced the battery on your coin (commonly known as"button" or "button" or "watch") and the fob isn't working it could be due to an internal circuit board issue. In the majority of cases, reprogramming your fob will solve the issue. You can find directions on how to do this for all vehicles by searching YouTube or looking through the owner's manual.
It is possible to replace the metal retaining clips that keep the coin battery in place. If they lose tension, it could prevent your coin battery from being properly seated, causing your remote to malfunction.

In some instances it may be necessary to install the software again in your body control module, as well.
Interference
Interference can also cause the key fob to be unable to receive or transmit an signal. This could occur if the key fob is near the radio transmitter (cell phones or radar detectors) or another source of electromagnetic radiation. Other reasons why the key fob might not function include a poor connection to the buttons or damage to the internal chip, or water damage.
