Reasons Your Fiat 500 Key Fob Won't Work

A key fob from Fiat 500 is a convenient way to unlock the doors and start the car. There are many reasons the key fob might stop working. This includes a dead coin-battery and water damage, as well as issues with the receiver module, and interference.

This listing is for a NEW replacement Fiat Flip Key Remote that looks like the Ilco brand. It must be professionally programmed (click here to find local locksmiths in the automotive industry). This remote includes trunk, lock and unlock buttons.

Dead Coin Battery

A dead battery is probably the most common reason for your 500 key fob not working. Modern key fobs come with a limited operating range, and must be within only a few feet from the vehicle to function. If you're far from your vehicle, and you 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, replace the coin cell battery (Part number CR2032) with a fresh one from a reputable brand like Panasonic, Duracell, or Energizer. They are available at the local hardware store or online.

After you've replaced the coin cell battery you can test it by standing close to your Fiat 500 and pressing the buttons. The car will blink its parking lights, and the key fob should be able to operate the lock and unlock buttons.

If your fob's key isn't working after replacing the battery, there may be water damage that has prevented it from communicating with the module in your vehicle. Water damage can happen in a variety of ways, ranging from a light splash to submerging the fob in salt water at the beach. If you suspect that your fob has been exposed to water, put it in a bag of rice to draw out the moisture. If this doesn't work your fob is likely to need to be reprogrammed by an experienced locksmith or dealer.

Water Damage

While the fob has some rubber seals that keep water from the electronic chip inside the device, submerging it into the ocean or washing it in a machine could cause water damage. Saltwater can cause the circuit board to short and then cease to function. Getting the fob wet is not a good idea, but if you drop it into a glass of water or fail to take it out of your pants pocket before running the washing machine do not give up hope.

First take the battery off the fob. Before replacing the battery clean the electronic chip using isopropyl or a similar product. Check the fob again to check if it's working. If the key does not function, it may have to be reprogrammed. This is usually handled by an auto locksmith or dealer.

If the key is a newer model and was not programmed to your car It is likely that it needs to be replaced completely. A professional locksmith in the automotive industry can do this job. The locksmith will require the key cut to match your vehicle's ignition. They'll also need to program the fob into your car's system. This is a cheap and quick process that could be completed within the same day.

Receiver Module Issues

One of the most common reasons your 500 key fob won't be functioning is that it's out of range. The remote has a range of 30 feet, which means when you're too far away from your vehicle, it won't respond to your commands. It is possible to remedy this by moving your remote closer to your car until it responds.

If your fob isn't working after you replace the battery for the coin, also called a "button", "watch" or "button" or "button", it could be due to a problem with the circuit board inside. Reprogramming the fob typically resolves the issue. The instructions are available for the majority of vehicles on YouTube or in the owner's guide.

It's possible that you need to replace the metal clips that keep the coin battery. If they loose tension, it could prevent your coin battery from sitting properly, causing your remote to malfunction.

In rare instances the fob might become disconnected from your vehicle due to software issues or hardware issues. This could cause a significant headache, but you can often fix this by visiting an auto locksmith to reprogram your fob for you. In certain instances it is possible that the software will require reinstallation to your body control modules.

Interference


Interference can also cause the key fob not to receive or transmit a signal. This could occur if the key fob is close to radio transmitters (cell phones, radar detectors) or any other source of electromagnetic radiation. The key fob could not function due to a poor connection with the buttons, water damage or damage to the internal chips.

If the key fob suddenly stopped working, suddenly or even after trying everything you can at home to fix it e.g. replacing the battery, reprogramming it and using the spare key fob, you may have a defective receiver module on your 500. The receiver module is situated under the dash and receives the radio frequency signals from the key fob. It transforms the signals into electronic commands that are then translated by the vehicle.

Fortunately, there's an easy method to reset all of the on-board systems in your 500 keys, including the key fob. Disconnect the 12 volt battery for about 15 minutes, by removing the negative cable first then the positive cable. Then, reconnect fiat punto key . This will remove any remaining electricity and then restart the car's computer system, which can help you get your key fob working again. If the issue persists, you should seek the advice of an expert technician. They will be able to identify the root cause of any problems.
