Dead Coin Battery
A dead battery is the most common reason for your 500 key fob not functioning. Key fobs of today have only a limited range of operation and must be within a few inches of your vehicle in order to function. If you're far from your vehicle and you push the keyfob button it will not respond, and display the message "Key Fob Not Detected".
If this happens, replace the coin-cell battery (Part Number CR2032) by a new one of a reputable brand like Panasonic Duracell or Energizer. You can find them at the local hardware store or online.
After you've replaced the battery of your coin cell you can test it by standing close to your Fiat 500 and pressing the buttons. The parking lights should blink and the key fob should operate the lock and unlock switch.
If the key fob doesn't work after replacing the battery, it could have water damage that stops it from connecting to the receiver module in your vehicle. Water damage can happen in many ways, such as the simple splash or submerging your key fob in saltwater at the beach. If you suspect that your fob has been exposed to water, you can place it in a rice bag to draw out the moisture. If this doesn't work, you will have to get your fob changed by an auto locksmith or a dealer.
Water Damage
Water damage can occur if you immerse the fob in the ocean, or wash it in a washer. Saltwater can cause the circuit board to become shorted and eventually end up dying. 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 do not remember to take it out of your pocket before you run the washing machine and you don't have a chance, don't give in.
Take the battery off first. Clean the electronic chip with isopropyl alcohol or a similar product and dry it thoroughly before replacing the battery. Test the fob afterward to verify if it's working. If the fob doesn't work, it may need to be reprogrammed. G28 is usually done by an auto locksmith or dealer.
If the key is more recent and has never been programmed to your car It is likely that it needs to be replaced completely. A professional locksmith in the automotive industry can do this job. The locksmith will have to cut the key to match the ignition of your vehicle. They'll also have to program the fob into the system of your car. This is a simple and cost-effective procedure that can be completed within the next day.
Receiver Module Issues
The 500 key fob you have may not work because it's out of range. The remote typically has an area of 30 feet or less and if it's far from your car, it won't respond to your commands. This can easily be resolved by moving it closer to your vehicle until it begins responding.
If your fob does not work after replacing the battery in the coin, also known as a "button", "watch" or "button" it could be due to a problem with the internal circuit board. Reprogramming the fob usually resolves this problem. You can find the instructions for most vehicles on YouTube or in the owner's manual.
It could be necessary to replace the clips made of metal that hold the coin batteries in their place. If they lose tension, it could hinder the battery from being properly seated and could cause the remote to malfunction.
In rare instances, the fob might be out of the vehicle's sync because of software or hardware problems. You can fix this issue by visiting your local dealer or auto-locksmith to reprogram your key fob. In some instances the software may require reinstallation into your body control modules.
Interference
Interference can also cause the key fob to not receive or transmit an signal. This may happen if the keyfob is located in close proximity to a radio transmitter, like a cellphone or radar detector. Other reasons why the key fob may not function 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 and you've tried everything you can do at home to fix it e.g. You may have a faulty 500 receiver module in the event that you've tried replacing the battery, reprogramming, and using an alternative key fob. The receiver module is situated under the dash and is able to pick up the radio frequency signals from the key fob. It then converts them into electronic commands that the vehicle interprets.
There is a straightforward method to reset the 500's in-board system, including the keyfob. Disconnect the battery 12 volt for about 15 minutes by removing the negative cable and then the positive cable. Reconnect the battery. This will eliminate any remaining electricity, and restart the computer of your car. This could help you get your key fob to function again. If the issue persists it is recommended that you consult an expert certified technician. They can determine the root of your problem.
