Dead Coin Battery

A dead battery is the most common reason for your 500 key fob not functioning. Modern key fobs come with a restricted operating range, 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 car will not respond, and will display a "Key Fob Not Detected" message in the instrument cluster.

If this happens, replace the battery in the coin cell (Part number CR2032) with a brand new one from a reputable manufacturer like Panasonic, Duracell, or Energizer. You can find them 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 should blink its parking lights, and the key fob should work the lock and unlock switches.

If the fob's key doesn't function after replacing the battery, it could have water damage that prevents it from connecting to the receiver module inside your car. 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 your fob was exposed to water, put it in a dry rice bag to draw the moisture back out. If this fails, you'll need to have the fob reprogrammed either by an auto locksmith or dealer.

Water Damage

Water damage can happen if you immerse the fob in the ocean or wash it in a machine. Saltwater is especially dangerous to the circuit board of the fob, causing it to short out and eventually end up dying. It's not the best idea to let the fob get wet, but don't give it up when you accidentally drop it in water, or fail to take it out of your pocket.

First remove the battery from the fob. Clean the electronic chip using isopropyl alcohol or another similar product and dry it thoroughly before replacing the battery. Test the fob afterward to determine if it's functioning. If the key still doesn't work, it may need to be reset. This is usually done by an auto locksmith or dealer.

If your key is a bit older and is not programmed for your car, you will need to replace it completely. This is a simple process that can be completed by a professional locksmith for automotive use. The locksmith will have to cut the key to match the ignition in your vehicle. The locksmith will also have to reprogram your fob in the vehicle's system. This is an affordable and quick process that could be completed in the same day.

Receiver Module Issues

One of the most common reasons why your 500 key fob could stop working is because it's out of range. The remote has a range of 30 feet. Therefore, in the event that you are far away from your vehicle it won't be able to respond to your commands. It is possible to fix this by moving the remote closer to your car until it responds.

If your fob isn't working after replacing the battery in the coin, also known as a "button", "watch" or "button" It could be a problem with the circuit board inside. In the majority of cases, reprogramming your fob will fix the problem. The instructions are available for the majority of vehicles on YouTube or in the owner's guide.

You may have to replace the metal clips that hold the coin battery in place. If they lose tension it could prevent your coin battery from sitting properly and cause your remote to malfunction.

In rare instances, the fob may be out of the vehicle's sync because of hardware or software issues. This can be a major issue, but you are able to usually resolve this issue by visiting a local dealer or auto locksmith to reprogram your fob. In certain instances it is possible that the software will need to be reinstalled in your body control modules.

Interference

Interference can also cause the key fob not to receive or transmit a signal. This can happen when the key fob is close to radio transmitters (cell phones or radar detectors) or another source of electromagnetic radiation. Other reasons the key fob may not function could be due to a weak connection to the buttons and internal chip, or water damage.

If the key fob failed to work one day suddenly and you've tried everything you can at home to fix it e.g. replacing the battery, reprogramming, and using the spare key fob, it could have a faulty receiver module on your 500. The receiver module, which is located beneath the dashboard, picks up radio frequency signals from your key fob. Then, it converts them into electronic commands that the vehicle interprets.

Fortunately, there's an easy way to reset all of the on-board systems in your 500 keys, including the key fob. Disconnect the battery for 15 minutes by taking off first the negative cable, then the positive cable. Then reconnect the battery. This will eliminate any remaining electric current, and also restart the computer of your car. This can help get your key fob to function again. If the problem persists you should seek out an expert technician. They will be able to determine the root cause of any problems.
