If this happens, replace the battery of your coin cell (Part number CR2032) with a fresh one from a trusted brand such as Panasonic, Duracell, or Energizer. They are typically available at your local hardware store or online.
You can test the battery on your coin-cell by pressing the buttons while standing near your Fiat 500. The parking lights should flash and the key fob will operate the lock and unlock switches.
If your fob's key does not work 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 simply splashing or submerging the key fob in saltwater 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 does not work, you'll need to have the fob reprogrammed either by an auto locksmith or a dealer.
Water Damage
Water damage can occur if you immerse the fob into the ocean or wash it in a machine. Saltwater poses a particular risk to the circuit board of the fob which causes it to short out and eventually die. In the event that you let your fob get wet, it's not an ideal idea, but if you drop it into the water in a cup or forget to take it out of your pants pocket prior to running the washing machine Don't give up hope.
First remove the battery from the fob. Clean the electronic chip using isopropyl ethanol or a similar product and then dry it thoroughly before replacing the battery.

They'll also need to reprogram the fob in your vehicle's system. This is an affordable and fast process that can be completed within the same day.
Receiver Module Issues
The 500 key fob you have may not function because it's out of range. The remote typically has an operating range of 30 feet or less and if it's far away from your car it will not respond to your commands. You can remedy this by moving your 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 your fob doesn't function, it could have an internal circuit board problem. In the majority of cases, reprogramming your fob will fix the issue. You can find directions on how to do this for all automobiles by searching YouTube? or checking out the owner's manual.
You may have to replace the metal retaining clips that keep the battery of your coin in place. If they lose tension they could stop the battery from sitting properly, and this will cause your remote to malfunction.

Interference
Interference can also cause the key fob to not receive or transmit signals.

If the key fob has suddenly stopped working, out of the blue or even after trying every option at home to solve it e.g. replacing batteries, reprogramming or using the spare key fob, you could have a malfunctioning receiver module on your 500. The receiver module, located beneath the dashboard, detects radio frequency signals from your key fob. It converts them into electronic commands that the vehicle interprets.
