Reasons Your Fiat 500 Key Fob Won't Work

Dead Coin Battery
The most frequent reason that your 500 key fob will not function is a dead battery. Modern key fobs come with a limited operating range and should be within only a few feet from the car to operate. If you're far away from your vehicle and press the key fob button the car will not respond, and will display the "Key Fob Not Detected" message in the instrument cluster.
If this happens, simply replace the battery on your coin cell (Part number CR2032) by a new one from a trusted brand such as Panasonic, Duracell, or Energizer. They are usually available in your local hardware store, or online.
After you've replaced the battery in the coin cell, you can test it by standing in front of your Fiat 500 and pressing the buttons. The parking lights will flash and the key fob will operate the lock and unlock switch.
If your fob's key does not work after replacing the battery, there could be water damage that has prevented it from interacting with the module inside your vehicle. Water damage can happen in a variety of ways, from an accidental splash to submerging the fob into salt water at the beach. If you suspect that your fob was exposed to water, try putting it in a dry rice bag to draw the moisture back out. If this doesn't work, your fob is likely to need to be reset by a professional auto locksmith or the dealer.
Water Damage
Water damage can happen if you immerse the fob into the ocean, or wash it in a washer. Saltwater is particularly dangerous to the fob's circuit board, causing it to short out and eventually die. It's not a good idea to submerge the fob in water but don't give up even if you accidentally drop the fob in the water or don't take it out of your pocket.
First remove the battery from the fob. Clean the electronic chip using isopropyl or a similar product and dry it thoroughly before replacing the battery. Then, test the fob to check if it functions. If the key does not function it could need to be changed. G28 Car Keys is usually done by a dealer or professional auto locksmith.
If the key is a newer model and hasn't been programmed to your vehicle, it will likely need to be replaced completely. A professional locksmith in the automotive industry will be able to complete this process. The locksmith will require the key to be cut to match your car's ignition. They will also need to reprogram the fob to your car's system. This is an affordable and quick process that could be completed the same day.
Receiver Module Issues
One of the simplest reasons your 500 key fob may stop functioning is that it's out of range. The remote has a range of 30 feet, so in the event that you are far away from your vehicle, it won't respond to your commands. You can easily fix this by moving the remote closer to your car until it responds.
If you've replaced the battery on your coin (commonly called"button" or "button" or "watch") and your fob doesn't function, it could have an internal circuit board problem. Reprogramming the fob usually resolves the issue. You can find the instructions on how to do this on the majority of vehicles by searching YouTube or reading the owner's manual.
It may be necessary to replace the metal clips that hold the coin batteries in their place. If they loose tension it can prevent the coin battery from being properly seated and could cause your remote to malfunction.
In rare instances, the fob may be out of the vehicle's sync because of hardware or software problems. This could cause a significant trouble, but you could often fix this by visiting an auto locksmith to reprogram your fob. In certain instances it may be necessary to install the software again in your body control module too.
Interference
Interference can also cause the key fob to not receive or transmit the signal. This could occur if the key fob is in proximity to the radio transmitter (cell phones, radar detectors) or any other source of electromagnetic radiation. Other reasons the key fob might not work include a poor connection to the buttons or the internal chip or water damage.
If the key fob stopped working one day without notice or after trying everything you can do at home to fix it e.g. battery replacement, reprogramming and using the spare key fob, you may have a damaged receiver module on your 500. The receiver module is situated under the dash, and it picks up the radio frequency signals from the key fob. It converts them to electronic commands that the vehicle interprets.
Luckily, there is an easy method of resetting all of the on-board systems in your 500 device, including the key fob. Disconnect the battery 12 volt for about 15 minutes by removing the negative cable first then the positive cable. Reconnect the battery. This will erase any remaining electricity, and allow you to restart the computer in your car. This can help you get your key fob to work again. If the problem persists you should seek out an experienced technician. They'll be able to determine the root of your issue.
