Dead Coin Battery

A dead battery is the most common reason for your 500 key fob not functioning. Key fobs of today have limited operating range and must be within a few inches of the vehicle in order to function. If you are far from your vehicle and 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 fresh one of a trusted brand such as Panasonic Duracell or Energizer. They are typically available in your local hardware store or online.

You can test the battery in the coin-cell by pressing the buttons while you are standing close to your fiat replacement key 500. The car should flash its parking lights, and the key fob will operate the lock and unlock buttons.

If the fob's remote doesn't work after replacing the battery, it might be damaged by water, which prevents it from connecting to the receiver module inside your vehicle. Water damage can occur in a variety of ways, such as an easy splash or submerging the key fob saltwater at the beach. If you think your fob was exposed to water, put it in a rice bag to draw out the moisture. If this doesn't work, your fob may need to be reprogrammed by a professional auto locksmith or by the dealer.

Water Damage

Damage to the water supply can occur if you immerse the fob in the ocean, or wash it in a washing machine. Saltwater poses a particular risk to the fob's circuit board, causing it to short out and eventually die. If you get the fob wet, it's not a good idea but if you accidentally drop it in a glass of water or forget to take it out of your pocket before you run the washing machine do not give up hope.

First take the battery off the fob. Clean the electronic chip with isopropyl alcohol or a similar product and then dry it thoroughly before replacing the battery. Test the fob afterward to check if it's functioning. If the fob doesn't work, it may need to be reprogrammed. This is usually handled by a dealer or professional auto locksmith.

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

Receiver Module Issues

One of the simplest reasons your 500 key fob won't be functioning is because it's out of range. The remote typically has 30 feet of range or less, and if it's too far away from your car it will not respond to your commands. It can be solved by moving it closer to your vehicle until it starts responding.

If you've replaced the battery on your coin (commonly called a "button" or "watch") and the fob won't work It could be because of an internal circuit board problem. Reprogramming the fob usually resolves this issue. You can find instructions on how to do this for most vehicles by searching YouTube or reading the owner's manual.

It is possible to replace the metal retaining clips that hold the coin battery in place. If they become loose, it may prevent your battery from sitting 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 or hardware issues. You can fix this problem by visiting your local auto-locksmith or dealer to reprogram your key fob. In some cases it may be necessary to reinstall the program in your body control module too.

Interference

Interference can also cause the key fob to not be able to receive or transmit an signal. This can occur when the keyfob is in close proximity to a radio transmitter like a cellphone or radar detector. Other reasons why the key fob might not work include a weak connection to the buttons or damage to the internal chip, or water damage.

If the key fob has failed to work one day without notice and you've tried everything you can do at home to solve it e.g. replacing the battery, reprogramming it and using the spare key fob, it could have a malfunctioning receiver module on your 500. The receiver module is situated under the dash, and it picks up the radio frequency signals from the key fob. It converts the signals into electronic commands that are then read by the vehicle.

Luckily, there is an easy method to reset every single system on board in your 500 keys, including the key fob. Disconnect the battery of 12 volts for about 15 minutes by removing the negative cable first then the positive cable. Reconnect the battery. This will remove any remaining electricity and restart the car's computers, which can help you get your key fob working again. If the problem persists you should seek out an expert certified technician. They will be able to identify the root of any problems.
