Fiat 500 Key Fob Replacement
If your 500 keyfob ceases working, use another one to determine if it will be recognized by the car. If it does, then the issue is likely with the original fob's battery, or water damage.
First replace the battery. Make sure the new #CR2032 coin cell battery is correctly inserted with the "+" side facing down in the fob.
Dead Battery
The majority of the time, when a fob doesn't work, it's because the battery is dying. This isn't a problem to repair and most fobs give you a warning when the battery is getting depleted. You can find the correct procedure on YouTube for almost every key fob in your car or in your owner's manual. You can also take it to a local locksmith or the dealer that sold it to you to replace it.
Sometimes, a fob may not function and there could be a problem with the internal circuit board. This isn't a lot of common but it is possible to happen. If you drop the fob on something sharp, it can damage the internal chip. It can also happen if you use an aftermarket key and the fob doesn't work. In this case you'll be required to go to a dealer or a locksmith and get it reprogRammed to work with your 500.

Chips damaged
A fiat 500 key fob is an electronic device that transmits the signal to the car to start when you press the button. It has a microchip which contains information about the code required to communicate with the car. If the chip is damaged, it will not transmit the correct code and the car won't start. Locksmiths can fix this type of damage. United Locksmith can complete this service on both classic and modern models, so don't hesitate to call us.
Locksmiths can program an entirely new key fob. This is less expensive than going to a dealer and will function similarly. Locksmiths will require specific details from you, such as the year that your car was manufactured and the name of its model.
Rub the chip with an old dollar bill if you're not sure what to do. The copper in the bill is abrasive, and will remove dirt and oxidation. However, it won't harm the microchip. The chip might not be repairable when it's physically damaged. This could happen if you lose it, drive it over with your car or experience any other kind of physical trauma.
Water Damage
Whether you accidentally dropped your keys in the water, put them in your pocket while you were swimming at the beach, or splashed them with water during a rainy day you can be sure that your key fob is likely to suffer water damage. Even if you only have a tiny amount of water on the key, it can cause serious problems to its electronics and prevent it from working properly.
It is usually possible to fix this issue by taking the fob off and cleaning it using a paper towel. Once the fob is dry you can then replace its battery and it will begin functioning normally.
You can also take the fob to a local locksmith or auto shop to have it professionally cleaned and programmed. They can employ special equipment to ensure that the key fob works with the computer in your car.
If the key fob of your Fiat 500 stops working, you might feel angry and anxious. You might be tempted to visit a dealer to have your key fob replaced but this could be expensive and time-consuming. A locksmith can replace your key fob without needing to visit an establishment. They are a better choice over a dealer as they can handle all aspects of the replacement of your car's key fob without the requirement for a dealership visit.
Pairing Issues
If you drop your keyfob or it ceases to function and nothing else seems to be wrong, it could be the chip. This could be due to water damage or an unresponsive battery.
This can be accomplished by simply following the directions in your owner's manual. If you're having difficulty or your manual isn't working and you need to have an automotive locksmith complete this task. This will ensure that the chip won't be fried and will likely be the cheapest solution.
Another problem with some 500 owners is that the key fob can't lock the car. This could be a major issue if you're at the gas station to fill up. Some owners have reported the locking mechanism of their 500's malfunctioning and requiring replacement of the entire intermediate shaft of the steering. This issue has been cited in a technical service bulletin (TSB) by Fiat.
A reputable locksmith can assist you if your Fiat is experiencing problems. They'll duplicate your key or they can make you new keys that lock and start the car. They can do this without having access to your old key, and it's usually cheaper than buying a new one from the dealer.
