Dead Coin Battery
The most common reason your 500 key fob doesn’t work is a dead battery. Key fobs of today have limited operating range and must be within just a few inches of the vehicle in order to work. If you are not within your vehicle and you press the keyfob button, it will not respond and display the message “Key Fob Not Detected”.
If this happens you need to replace the battery of your coin-cell (Part Number CR2032) by a fresh one of a trusted brand such as Panasonic Duracell or Energizer. They are usually available in your local hardware store or online.
After you’ve changed the battery on the coin cell, you can test it by standing near your fiat stilo key 500 and pressing the buttons. The parking lights should blink and the key fob will operate the lock and unlock switches.
If the fob’s remote doesn’t work after replacing the battery, it could have water damage that stops it from connecting to the receiver module in your car. Water damage can happen in many ways, such as an easy splash or submerging the key fob in saltwater at the beach. If you suspect your fob has been exposed to water, try placing it in a dry rice bag to draw the moisture out. If this doesn’t work, you will have to get your fob changed by an auto locksmith or dealer.
Water Damage
While the fob has some rubber seals to keep water out of the chip’s electronic circuit and out of the ocean or washing it in a machine could cause water damage. Saltwater can cause the circuit board to short and then end up dying. In the event that you let your fob get wet, it’s not an ideal idea but if you drop it in a glass of water or forget to remove it from your pants pocket prior to running the washing machine, don’t give up hope.
First, remove the battery. Clean the electronic chip using isopropyl or a similar product and dry it thoroughly before replacing the battery. Next, test the fob to check if it functions. If the fob doesn’t work, it may have to be reset. This is typically handled by a dealer or professional auto locksmith.

It’s a simple and inexpensive process that can be completed in the same day.
Receiver Module Issues
One of the most common reasons your 500 key fob won’t be working is because it’s out of range. The remote’s range is of 30 feet. So in the event that you are far from your car, it won’t respond to your commands. It can be solved by moving it closer to your vehicle until it begins responding.
If you’ve replaced your coin battery (commonly called”button” or “button” or “watch”) and your fob still won’t work, it could have an internal circuit board problem. Reprogramming your fob can resolve the issue. There are instructions on how to program fiat 500 key fob to do this on the majority of automobiles by searching YouTube or consulting the owner’s manual.
You may have to replace the metal clips that hold the coin battery in place. If they lose tension, they could stop the battery from being seated properly and cause your remote to malfunction.
In rare cases the fob might be out of connection with your vehicle as a result of hardware or software problems. It is possible to fix this issue by visiting your local auto-locksmith or dealer to reprogram your key fob. In some instances the software might require reinstallation into your body control modules.
Interference
Interference can also cause the key fob to not be able to receive or transmit signals. This could happen if the key fob is close to radio transmitters (cell phones and radar detectors) or another source of electromagnetic radiation. The key fob may not function because of a weak connection to the buttons or water damage, or damage to the internal chips.
If the key fob suddenly stopped working, in the middle of the night, or after trying every option at home to solve it e.g. It could be a defective 500 receiver module after you’ve tried replacing the battery, reprogramming, and using an alternative key fob. The receiver module, located under the dashboard, detects radio frequency signals from your key fob. It converts them into electronic commands that the vehicle interprets.
Luckily, there is an easy method of resetting every single system on board in your 500 keys, including the key fob. Disconnect the battery for 15 minutes, removing first the negative cable, then the positive cable. Then, reconnect the battery. This will remove any remaining electricity, and restart the car’s computer. This will help you get your key fob working again. If the issue persists you should seek out a certified technician. They will be able to determine the root of your problems.
