Dead Coin Battery

The most frequent reason why your 500 key fob will not function is the battery is dead. Modern key fobs only have only a limited range of operation and must be within just a few inches of the vehicle to work. If you are far from your vehicle, and you press the keyfob button, it won't respond and display the message "Key Fob Not Detected".

If this happens, replace the battery of your coin cell (Part number CR2032) with a fresh one from a reputable manufacturer like Panasonic, Duracell, or Energizer. You can find them in your local hardware store, or online.

You can test the battery of your coin-cell by pressing the buttons while standing near your fiat keys 500. The parking lights should 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 could be water damage that is preventing it from communicating with the module inside your vehicle. Water damage can occur in a number of ways, from a light splash to submerging the fob salt water 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 that doesn't work, your fob will probably require reprogramming by a professional auto locksmith or the dealer.

Water Damage

Damage to the water supply can occur if you submerge the fob in the ocean or wash it in a washer. Saltwater can be particularly harmful to the fob's circuit board that can cause it to short out and eventually end up dying. It's not good to submerge the fob in water however, but don't give it up if you accidentally drop it in water or fail to take it out of your pocket.

First take the battery off the fob. Before replacing the battery clean the electronic chip with isopropyl or another similar product. Check the fob to see if it is functioning. If the key still doesn't function, it may need to be changed. This is usually handled by a professional or dealer auto locksmith.

If the key is more recent and hasn't been programmed to your car it is likely to need to be replaced completely. This is a simple procedure that can be handled by a professional automotive locksmith. The locksmith will need the key to be cut to match the car's ignition. The locksmith will also have to reprogram the fob into the car's system. This is a fast and cost-effective process which can be completed within the same day.

Receiver Module Issues

One of the simplest reasons your 500 key fob won't be functioning is that it's out of range. The remote's range is of 30 feet, which means in the event that you are far from your car, it won't respond to your commands. It can be solved by moving closer to your vehicle until it starts responding.

If your fob won't work after you replace the coin battery, also known as a "button", "watch" or "button" it may be due to a malfunction on the circuit board inside. In most cases, reprogramming the fob will fix the problem. You can find the instructions for the majority of vehicles on YouTube or in the owner's guide.

You may need to replace the metal clips that keep the battery of your coin in place. If they loose tension, they could stop the coin battery from being properly seated, and this will cause your remote to malfunction.

In rare instances the fob might become disconnected from your vehicle because of software or hardware issues. This could be a huge problem, but you can often fix this by visiting an auto locksmith to have them reprogram your fob. In some instances the software may require reinstallation into your body control modules.

Interference

In addition to a dead coin battery the key fob could not be able to receive or transmit a signal due to interference. This could happen when the keyfob's location is in close proximity to a radio transmitter like a cellphone or radar detector. The key fob may not function due to a poor connection with the buttons, water damage or damage to the internal chips.

If your key fob suddenly stopped working, or if you've tried everything at home to solve the issue (e.g. You may have a faulty 500 receiver module in the event that you've tried replacing the battery, reprogramming, and using a spare key fob. The receiver module is located under the dash and receives the radio frequency signals from the key fob. It converts them to electronic commands that the vehicle interprets.

Luckily, there is an easy method to reset all of the onboard systems in your 500 device, including the key fob. Disconnect the 12 volt battery for approximately 15 minutes by disconnecting the negative cable first then the positive cable. Then, reconnect the battery. This will remove any remaining electrical charge and restart the car's computers, which can help the key fob to function again. If the issue continues you should seek out an expert certified technician. They will be able to identify the root cause of any problems.
