Dead Coin Battery

The most common reason your 500 key fob doesn't function is an inactive battery. Modern key fobs operate with a limited range of operation, and should be within some feet of the vehicle to function. If you are far from 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 occurs, replace the coin-cell battery (Part Number CR2032) with a new battery of a reliable brand, like Panasonic Duracell or Energizer. You can find them at the local hardware store or online.

You can test the coin-cell battery by pressing the buttons while standing close to your Fiat 500. The parking lights should light up and the key fob should operate the lock and unlock switches.

Receiver Module Issues

The 500 key fob could not work because it's out of range. The remote typically 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. It is possible to fix this by moving the remote closer to your car until it responds.

If you've replaced the battery on your coin (commonly known as"button" or "button" or "watch") and the fob won't work it could be due to an internal circuit board problem.
