Reasons Your Fiat 500 Key Fob Won't Work

Dead Coin Battery
The most common reason the 500 key fob won't function is due to a dead battery. Modern key fobs operate with a limited range of operation, and must be within only a few feet from the vehicle in order to function. If you are far from your vehicle, and you press the key fob button the car won't respond, and will display the "Key Fob Not Detected" message in the instrument cluster.
If this happens, replace the battery of your coin cell (Part number CR2032) with a brand new one from a reputable brand like Panasonic, Duracell, or Energizer. They are usually available at your local hardware store, or online.
You can test the battery of your coin-cell by pressing the buttons while standing near your Fiat 500. The car will flash its parking lights and the key fob should be able to operate the lock and unlock switches.
If your key fob isn't working even after replacing the battery, it may be water damage which has prevented it from communicating with the module in your vehicle. Water damage can happen through a variety of methods, including an easy splash or submerging your key fob in saltwater at the beach. If you suspect that your fob was exposed to water, place it in a rice bag to draw out the moisture. If this doesn't work, your fob is likely to require reprogramming by an experienced auto locksmith or dealer.
Water Damage
Water damage can happen if you submerge the fob in the ocean or wash it in a washer. Saltwater can be particularly harmful to the fob's circuit board and can cause it to short out and eventually die. It's not good to soak the fob in water, but don't give it up if you accidentally drop it in water, or fail to take it out of your pants pocket.
First, remove new key for fiat 500 . Clean the electronic chip with isopropyl or a similar product and dry it thoroughly before replacing the battery. Next, test the fob to test if it works. If the key does not work, it may have to be changed. This is usually done by a professional or dealer auto locksmith.
If your key is a bit older and is not programmed for your car You will need to replace it completely. A professional locksmith for cars can carry out this simple task. The locksmith will require the key cut to match your car's ignition. The locksmith also needs to reprogram the fob into the vehicle's system. This is a cheap and fast process that can be completed the same day.
Receiver Module Issues
The 500 key fob you have may be inoperable because it's out of range. The remote has a range of 30 feet. Therefore, should you be too far from your vehicle, it won't respond to your commands. You can solve this issue by moving the remote closer to your vehicle until it responds.
If you've replaced the battery on your coin (commonly called a "button" or "watch") and the fob isn't working It could be because of an internal circuit board problem. In the majority of cases, reprogramming your fob will solve the issue. The instructions are available for the majority of vehicles on YouTube or in the owner's guide.
It is sometimes necessary to replace the clips made of metal that hold the coin batteries in their place. If they lose tension it can prevent the coin battery from sitting properly and can result in the malfunction of your remote.
In rare instances, the fob may become disconnected from your vehicle due to software or hardware issues. This could be a huge problem, but you can frequently fix this issue by visiting a local dealer or auto locksmith to have them reprogram your fob. In some instances, they may need to reinstall the software on your body control module, too.
Interference
Interference can also cause the key fob not to receive or transmit signals. This can happen when the key fob is located near the radio transmitter (cell phones and radar detectors) or another source of electromagnetic radiation. Other reasons the key fob may not function could be due to a weak connection to the buttons and internal chip or water damage.
If the key fob failed to work one day without notice or even after trying every option at home to resolve 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 located under the dash and receives the radio frequency signals from the key fob. It transforms the signals into electronic commands, which are then read by the vehicle.
There's a quick and easy way to reset the 500's internal system including the keyfob. Disconnect the battery for 15 minutes by taking off first the negative cable, then the positive cable. Then, reconnect the battery. This will get rid of any remaining electricity and restart the car's computers. This could help the key fob to function again. If the problem persists you should speak with an expert technician. They can identify the root cause of your problems.
