Reasons Your Fiat 500 Key Fob Won't Work
Dead Coin Battery The most common reason your 500 key fob doesn't function is an inactive battery. Modern key fobs have a limited operating range, and should be within only a few feet from the car to operate. If you are far from your vehicle, and you 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 of your coin cell (Part number CR2032) with a brand new one from a reputable manufacturer such as Panasonic, Duracell, or Energizer. You can usually find them in your local hardware store or online. You can test the battery in the coin-cell by pressing the buttons while standing close to your Fiat 500. The parking lights will flash and the key fob should operate the lock and unlock switch. If your fob's key does not work after replacing the battery, it might be water damage that prevents it from connecting to the module inside your vehicle. Water damage can happen in many ways, such as simply splashing or submerging the key fob in saltwater at the beach. If you believe your fob was exposed to water, put it in a bag of rice to draw out the moisture. If this does not work, you'll have to get your fob reprogrammed either by an auto locksmith or a dealer. Water Damage While the fob comes with rubber seals that keep water from the electronic chip inside, submerging it in the ocean or washing it in a machine can cause water damage. Saltwater is especially dangerous to the fob's circuit board and can cause it to short out and eventually die. Getting the fob wet is not a good idea, but if you drop it into a cup of water or fail to take it out of your pants pocket prior to running the washer and you don't have a chance, don't give in. Take the battery off first. Clean the electronic chip with isopropyl alcohol or another similar product and dry it thoroughly before replacing the battery. Next test the fob to verify if it is working. If the key still doesn't work, it may have to be changed. This is usually handled by an auto locksmith or dealer. If your key is older and is not programmed for your car, you will need to replace it completely. A professional locksmith in the automotive industry can carry out this simple task. The locksmith will need to cut the key to match the ignition on your vehicle. They'll also need to reprogram the fob to your car's system. This is a cost-effective and quick process that could be completed on the same day. Receiver Module Issues One of the simplest reasons your 500 key fob may stop working is that it's simply out of range. The remote usually has an operating range of 30 feet or less and if it's 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 your coin battery (commonly called"button" or "button" or "watch") and the fob won't work It could be because of an internal circuit board issue. Reprogramming the fob typically resolves the issue. You can find the instructions on how to do this for most automobiles by searching YouTube or consulting the owner's manual. It could be necessary to replace the metal clips that hold the coin batteries in their place. If they become loose, it could prevent your coin battery from sitting properly, causing your remote to malfunction. In rare instances, the fob may be out of the vehicle's sync because of hardware or software issues. This could cause a significant problem, but you can frequently fix this issue by visiting a local dealer or auto locksmith to reprogram your fob for you. In some instances they might need to reinstall the software on your body control module too. Interference In addition to a dead battery on a coin The key fob might not be able to transmit or receive signals due to interference. This could happen if the key fob is close to a radio transmitter (cell phones or radar detectors) or another source of electromagnetic radiation. The key fob could not function because of a weak connection with the buttons, water damage or damage to the internal chips. If the key fob has suddenly stopped working, in the middle of the night, or after trying everything you can do at home to solve it e.g. You could have a malfunctioning 500 receiver module in the event that you've tried replacing the battery, reprogramming, or using a spare key fob. The receiver module, which is located beneath the dashboard, detects radio frequency signals from your key fob. It converts the signals into electronic commands, which are then processed by the vehicle. There's a simple method to reset the 500's internal system, including the keyfob. Disconnect the battery for 15 minutes, removing first the negative cable and 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 issue persists you should seek out an experienced technician. They will be able to identify the exact cause of issues. |
