Dead Coin Battery
A dead battery is probably the most common cause of your 500 key fob not functioning. Modern key fobs come with a restricted operating range, and should be within a few feet of the vehicle to function. If you're not close to your vehicle, and 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 happens, simply replace the battery on your coin cell (Part number CR2032) with a new one from a reputable manufacturer like Panasonic, Duracell, or Energizer. They are typically available at your 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 parking lights should light up and the key fob should operate the lock and unlock switches.
If the key fob won't work after replacing the battery, it may have water damage that stops it from connecting to the receiver module in your vehicle. Water damage can happen in a variety of ways, ranging from the slightest splash to submerging the fob salt water at the beach. If you suspect your fob has been exposed to water, try putting it in a dry rice bag to pull the moisture back out. If this doesn't work your fob may require reprogramming by an experienced auto locksmith or by the dealer.
Water Damage
While the fob has some rubber seals to keep water from the electronic chip inside and out of the ocean or washing it in a machine can cause water damage. Saltwater is particularly dangerous to the fob's circuit board that can cause it to short out and eventually end up dying. It's not the best idea to submerge the fob in water however, but don't give it up in the event that you accidentally drop it in the water or don't remove it from your pants pocket.
Take the battery off first. Clean the electronic chip using isopropyl alcohol or a similar product and dry it thoroughly before replacing the battery. Then check the fob to see if it works. If the fob doesn't work, it may have to be reset. This is typically done by a dealer or professional auto locksmith.
If the key is more recent and was not programmed to your vehicle, it will likely need to be replaced completely. A professional locksmith for cars can carry out this simple task. The locksmith must cut the key to match the ignition of your vehicle. The locksmith also needs to reprogram your fob in the car's system. This is a cost-effective and quick process that could be completed within the same day.
Receiver Module Issues
One of the simplest reasons why 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 far away from your car it will not respond to your commands. This can easily be resolved by moving closer to your vehicle until it starts responding.
If you've replaced the coin battery (commonly called a “button” or “watch”) and the fob won't work, it could have an internal circuit board problem. In most cases, reprogramming the fob can resolve the issue. The instructions are available for most vehicles on YouTube or in the owner's manual.
It's possible that you need to replace the metal retaining clips that keep the coin battery. If they lose tension, it could hinder the battery from sitting properly and cause your remote to malfunction.
In rare cases the fob might be out of the vehicle's sync because of software or hardware problems. It is possible to fix this issue by visiting your local dealer or auto-locksmith to reprogram your key fob. In certain instances, the software may also need to be reinstalled in your body control modules.
Interference
Interference can also cause the key fob not to receive or transmit the signal. This could happen if the key fob is in proximity to an electronic radio transmitter (cell phones, radar detectors) or another source of electromagnetic radiation. Other reasons the key fob might not work may be a lack of connection to the buttons or damage to the internal chip or water damage.
If the key fob been unable to function for a while suddenly or after trying everything you can at home to fix it e.g. replacing the battery, reprogramming it and using the spare key fob, you may have a defective receiver module on your 500. The receiver module, 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 method of resetting all of the onboard systems in your 500 and include the key fob. Disconnect the battery 12 volt for about 15 minutes, by disconnecting the negative cable first then the positive cable. Then, reconnect the battery. This will get rid of any residual electricity and restart the car's computer system, which could help the key fob to function again. If the problem persists you should speak with an experienced technician. They will be able to identify the root of any issues.
