This listing is for an NEW replacement Fiat Flip Key Remote - look-alike Ilco brand that needs to be professionally programmed by a local automotive locksmith (click here for Locksmith Search). This remote includes lock, unlock and trunk buttons.

Dead Coin Battery

A dead battery is probably the most common reason for your 500 key fob being inoperative. Modern key fobs have a very limited range of operation, and must be within some feet of the vehicle to function. If you're far away from your vehicle and you press the key fob button the lost car Key Fiat won't 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 brand new key for fiat 500 one from a reputable brand such as Panasonic, Duracell, or Energizer. They are available at your local hardware store or on the internet.

You can test the battery in the coin-cell by pressing the buttons while standing near your fiat 500x key fob 500. The car should blink its parking lights and the key fob should operate the lock and unlock switches.

If the fob's key doesn't function after replacing the battery, it might be damaged by water that blocks it from communicating with the receiver module inside your car. Water damage can happen in many ways, such as a simple splash or submerging the key fob into saltwater at the beach. If you suspect your fob has been exposed to water, you can try placing it in a dry rice bag to pull the moisture out. If this isn't working, you'll require your fob to be reset by an auto locksmith or a dealer.

Water Damage

While the fob has some rubber seals that keep water from the electronic chip inside, submerging it in the ocean or washing it in a machine could cause water damage. Saltwater is particularly dangerous to the fob's circuit board, causing it to short out and eventually die. It's not a good thing to get the fob wet however, but don't give it up even if you accidentally drop the fob in water, or fail to take it out of your pocket.

First remove the battery from the fob. Before replacing the battery, clean the electronic chip using isopropyl or similar products. Then, test the fob to see if it works. If the key isn't working, it may have to be reset. This is usually done by an auto locksmith or dealer.

If the key is newer and has not been programmed to your car It will most likely need to be replaced completely. A professional locksmith in the automotive industry can do this job. The locksmith will have to cut the key to match the ignition of your vehicle. They'll also need to reprogram the fob to your car's system. This is a quick and inexpensive process which can be completed on the same day.

Receiver Module Issues

Your 500 key fob may be inoperable because it's out of range. The remote usually has an area of 30 feet or less and if it's far from your vehicle, it will not respond to your commands. You can fix this by moving the remote closer to your vehicle until it responds.

If your fob doesn't work after you replace the battery inside the coin, which is also called a "button", "watch" or "button", it could be due to an issue with the circuit board inside. Reprogramming your fob can resolve the issue. You can find instructions on how to do this for all vehicles by searching YouTube or reading the owner's manual.

It is possible to replace the metal clips that keep the coin battery. If they lose tension, it can prevent the battery from being seated properly and cause your remote to malfunction.

In rare cases it is possible that the fob will become desync'd with your vehicle due to software issues or hardware issues. This can cause a major problem, but you can usually resolve this issue by visiting an auto locksmith to reprogram your fob for you. In some instances it may be necessary to reinstall the program in your body control module as well.

Interference

Interference can also cause the key fob to be unable to receive or transmit the signal. This is possible when the key fob is near the radio transmitter (cell phones and radar detectors) or another source of electromagnetic radiation. Other reasons the key fob might not function include a poor connection to the buttons or damage to the internal chip, or water damage.

If your key fob suddenly stopped working, or you've tried everything at home to resolve it (e.g. replacing the battery, reprogramming it and using the spare key fob, you could have a defective receiver module on your 500. The receiver module, which is located under the dashboard, picks up radio frequency signals from your key fob. It converts them into electronic commands that the vehicle interprets.

There's a quick and easy way to reset the 500's in-board system, including the keyfob. Disconnect the battery for 15 minutes by removing first the negative cable and then the positive cable. Reconnect the battery. This will clear out any residual electricity and restart the car's computers. This could allow you to get your key fob working again. If the problem persists you should speak with an expert certified technician. They will be able to determine the exact cause of problems.
