Reasons Your Fiat 500 Key Fob Won't Work A key fob for the Fiat 500 makes it easy to open doors and start your vehicle. There are a variety of reasons why the fob won't work. This includes a dead coin-battery water damage, issues with the receiver module, and interference. This listing is for an NEW replacement Fiat Flip Key Remote – look-alike Ilco brand that must be professionally programmed by a local locksmith (click here for Locksmith Search). Includes lock, unlock and trunk buttons. Dead Coin Battery A dead battery is the main reason for your 500 key fob not functioning. Key fobs of today have limited operating range and must be within a few inches of the vehicle in order to function. If you're not close to your vehicle and press the key fob button, the car won't be able to respond, and will display the “Key Fob Not Detected” message in the instrument cluster. If this happens, simply replace the battery in the coin cell (Part number CR2032) with a brand new one from a reputable brand like Panasonic, Duracell, or Energizer. You can find them at your local hardware store, or online. After you've replaced the coin cell battery, you can test it by standing next to your Fiat 500 and pressing the buttons. The parking lights should blink and the key fob will operate the lock and unlock switches. If your key fob isn't working after replacing the battery, it may be water damage that hinders it from interacting with the module in your vehicle. Water damage can happen in a variety of ways, such as a simple splash or submerging the key fob in saltwater at the beach. If you suspect that your fob was exposed to water, you can try placing it in a dry rice bag to draw the moisture out. If this isn't working, you'll have to get your fob reset by an auto locksmith or dealer. Water Damage While the fob has some rubber seals that keep water out of the chip's electronic circuit it, submerging it in the ocean or washing it in a machine could cause water damage. Saltwater is especially dangerous to the fob's circuit board which causes it to short out and eventually end up dying. It's not a good idea to let the fob get wet, but don't give it up in the event that you accidentally drop it in water or fail to remove it from your pants pocket. First remove the battery from the fob. Before replacing the battery clean the electronic chip using isopropyl or another similar product. Test the fob afterward to determine if it's working. If the key isn't working, it may have to be reprogrammed. This is usually done by an auto locksmith or dealer. If your key is old and is not programmed to work with your vehicle then you'll need to replace it completely. A professional locksmith in the automotive industry can do this job. The locksmith will require the key to be cut to match your vehicle's ignition. They will also need to reprogram the fob in the system of your car. This is a cheap and quick process that can be completed within the same day. Receiver Module Issues One of the simplest reasons why your 500 key fob could stop working is that it's simply out of range. The remote typically has an area of 30 feet or less, and if it's too far from your vehicle, it won't respond to your commands. You can solve this problem by moving the remote closer to your car until it responds. If you've replaced the coin battery (commonly known as a “button” or “watch”) and your fob still won't work, it could have an internal circuit board issue. Reprogramming your fob can resolve this problem. You can find the instructions for most vehicles on YouTube or in the owner's guide. It is possible to replace the clips made of metal that hold the coin batteries in their place. If they loose tension, it could prevent your coin battery from sitting properly and cause your remote to malfunction. In rare instances, the fob might be out of the vehicle's sync because of software or hardware problems. TheKeyLab could cause a significant issue, but you are able to usually fix it by visiting a local dealer or auto locksmith to reprogram your fob for you. In some cases, the software may also need to be reinstalled in your body control modules. Interference Interference can also cause the key fob to not receive or transmit an signal. This is possible when the key fob is in proximity to radio transmitters (cell phones and radar detectors) or any other source of electromagnetic radiation. Other reasons why the key fob may not function include a weak connection to the buttons or the internal chip or water damage. If the key fob stopped working one day suddenly, or after trying everything you can do at home to fix it e.g. replacing the battery, reprogramming, and using the spare key fob, it could have a malfunctioning receiver module on your 500. The receiver module is located under the dash and picks up the radio frequency signals from the key fob. It then converts them into electronic commands that the vehicle interprets. Luckily, there is an easy way to reset every single system on board in your 500 and include the key fob. Disconnect the battery of 12 volts for about 15 minutes by removing the negative cable first then the positive cable. Reconnect the battery. This will clear out any residual electricity and restart the car's computers, which can help the key fob to function again. If the problem persists you should seek out a certified technician. They will be able to determine the root of your problem.
