Dead Coin Battery

The most frequent reason why your 500 key fob will not function is an inactive battery. Modern key fobs come with a restricted operating range, and must be within only a few feet from the car to operate. If you are far from your vehicle when you press the key fob button the car won't respond, and will display an "Key Fob Not Detected" message in the instrument cluster.

If this occurs you need to replace the battery of your coin-cell (Part Number CR2032) by a new one of a reliable brand, such as Panasonic Duracell or Energizer. They are available at the local hardware store or online.

You can test the coin-cell battery by pressing the buttons while standing near your fiat ducato replacement key 500. The parking lights should blink and the key fob will operate the lock and unlock switch.

If your key fob does not work after replacing the battery, it might 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 small splashes to submerging the fob in salt water at the beach. If you suspect your fob was exposed to water, you can try placing it in a dry rice bag to draw the moisture out. If this doesn't work your fob may require reprogramming by an experienced locksmith or dealer.

Water Damage

Water damage can occur when you submerge the fob in the ocean or wash it in a washer. Saltwater is especially dangerous to the circuit board of the fob that can cause it to short out and eventually die. In the event that you let your fob get wet, it's not an option but if you accidentally drop it in the water in a cup or don't remember to remove it from your pants pocket before running the washer, don't give up hope.

First, remove the battery. Clean the electronic chip using isopropyl alcohol or a similar product and then dry it completely before replacing the battery. Next test the fob to check if it functions. If the key still doesn't work, it may need to be reprogrammed. This is usually done by an auto locksmith or dealer.

If the key is newer and has never been programmed to your car, it will likely need to be replaced completely. This is a straightforward process which can be accomplished by a professional locksmith for automotive use. The locksmith will need the key to be cut to match your car's ignition. They'll also need to reprogram the fob for the system of your car. This is a cost-effective and quick process that could be completed on the same day.

Receiver Module Issues

One of the main reasons why your 500 key fob may stop working is that it's simply out of range. The remote usually has a range of 30 feet or less and if it's far from your car, it will not respond to your commands. This can be fixed by moving it closer to your vehicle until it begins responding.

If your fob isn't working after replacing the battery in the coin, also called a "button", "watch" or "button" it could be due to a problem with the circuit board inside. Reprogramming the fob usually resolves this issue. You can find the steps for the majority of vehicles on YouTube or in the owner's manual.

It is sometimes necessary to replace the metal clips that hold the coin batteries in their place. If they lose tension they could stop the coin battery from sitting properly and can cause the remote to malfunction.

In rare cases the fob might become desync'd with your vehicle because of software or hardware issues. It is possible to fix this issue by visiting your local auto-locksmith or dealer to reprogram your key fob. In some cases they may have to reinstall the software on your body control module too.

Interference

Interference can also cause the key fob to not be able to receive or transmit the signal. 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 why the key fob could not function include a weak connection to the buttons, damage to the internal chip or water damage.

If the key fob has failed to work one day without notice, or after trying every option at home to resolve it e.g. replacing the battery, reprogramming, and using the spare key fob, you may have a faulty receiver module on your 500. The receiver module, which is located beneath the dashboard, is able to pick up radio frequency signals from your key fob. It then converts them into electronic commands that the vehicle interprets.

Fortunately, there's an easy method of resetting all of the onboard systems in your 500, including the key fob. Disconnect the 12 volt battery for approximately 15 minutes by disconnecting the negative cable first then the positive cable. Reconnect the battery. This will get rid of any remaining electricity and then restart the car's computers. This could help get your key fob working again. If the issue continues, you should consult an expert technician. They can determine the root of your problem.
