Reasons Your Fiat 500 Key Fob Won't Work

Dead Coin Battery

The most frequent reason why the 500 key fob won't function is a dead battery. Key fobs of today have limited operating range and must be within a few inches of your vehicle in order to function. If you are further away from your vehicle and you press the keyfob button, it will not respond, and display the message "Key Fob Not Detected".

If this occurs then replace the battery for your coin-cell (Part Number CR2032) by a brand new one of a trusted brand such as Panasonic Duracell or Energizer. You can find them in your local hardware store or on the internet.

You can test the battery in the coin-cell by pressing the buttons while you're standing close to your Fiat 500. The car will flash its parking lights, and the key fob should work the lock and unlock buttons.

If the key fob won't work after replacing the battery, it might be damaged by water, which prevents it from communicating with the receiver module inside your vehicle.

If you think your fob was exposed to water, you can place it in a rice bag to draw out the moisture. If G28 Car Keys fails, you'll have to get your fob changed by an auto locksmith or dealer.

Water Damage

The fob does have rubber seals to keep water from the electronic chip inside and out of the ocean or washing it in a machine could cause water damage. Saltwater poses a particular risk to the fob's circuit board and can cause it to short out and eventually die. If you get the fob wet, it's not an ideal choice but if you accidentally drop it in the water in a cup or do not remember to take it out of your pants pocket before running the washer do not give up hope.

Receiver Module Issues

Your 500 key fob may not function because it's out of range. The remote usually has 30 feet of range or less, and if it's too far away from your car it will not respond to your commands. It's easy to solve this issue by moving the remote closer to your car until it responds.

If you've replaced the coin battery (commonly called a "button" or "watch") and the fob won't work It could be because of an internal circuit board issue.

Other reasons why the key fob might not work include a poor connection to the buttons or the internal chip or water damage.

If the key fob been unable to function for a while suddenly or after trying every option at home to resolve it e.g. It could be a defective 500 receiver module if you've tried replacing the battery, reprogramming, and using an alternative key fob. 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 processed by the vehicle.

There's a simple method to reset the 500's onboard system, including the keyfob.
