Fiat 500 Replacement Key Fob

It might be time to change the battery if your 500 remote key fob is not working. If you replace the battery and it's still not working the issue could be somewhere else.

At United Locksmith, we specialize in the creation of new keys for old automobiles. We have the tools and parts needed for this job.

Dead Coin Battery

The most frequent reason that your Fiat 500 key fob will not unlock or lock the doors is due to a dead battery. The battery for the coin cell in the key fob is likely to drain quickly if you don't use it frequently enough. If your remote began to show signs of weakening such as a loss of range and then completely stopped working it is likely that the battery is dead.

Metal clips keep the battery in place on the key fob. If the clips are not tightly secured, they could result in problems with contact that can prevent your remote from receiving power. With a small flathead screwdriver, push the clip that holds the retaining pin open to remove the battery and insert a new one. Use a battery that has the same voltage, size and specification as the original.


Water exposure can also cause the key fob to corrode or be damaged. Even a brief bath in soapy water can harm the electronic chip within. It's best to keep your key fob in a dry environment.

Water Damage

If your key fob isn't operating correctly, it could be due to water damage. Key fobs are fitted with rubber seals to protect them from being damaged by a light rain or splashes of water, however it is vital to keep your car keys away from the ocean, pool, and washing machine!

The key fob has an electronic chip that transmits a message to the immobilizer system of your car. The chip is what allows the 500 to start and lock. If it gets wet, however it will not function.

If you're trying to determine if your key fob is still functioning it is possible to clean the internal electronics using isopropyl or electronic cleaner. However, it's recommended to purchase a replacement from a dealer rather than trying to fix the key fob which has been submerged in salt water.

A replacement fob could cost you a little bit but it's far cheaper than having to have your Fiat 500 towed to a dealer and repaired there! In addition, you can do it yourself with only a few steps. Be sure to use the correct type of battery before you attempt to open your key fob. You can find step-bystep instructions for any car keyfob online.

Faulty Chip

The chip in the key fob connects directly with the immobiliser in your car to ensure that the vehicle will only start when the correct keys are used. If the chip is damaged or corrupted in any way, your car will not start.

Water damage or a dead cell battery are the most frequently cited reasons for an unreliable chip. It is recommended to leave the work to a professional locksmith, who will be able to replace the chip quickly and at a reasonable price.

If your key fob does not work after exposure to clean water from a tap or rain then remove the battery. Wipe down the electronic component using a paper towel. If the key fob will not work, there's a chance that it has malfunctioning components and need to be replaced.

Some people will go to their dealer when they are in need of a new Fiat key fob, but this could be a expensive option. If you are looking for a cost-effective way to get your Fiat key fob repaired make sure you contact United Locksmith. We have the tools and knowledge necessary to fix your Fiat key fob in a timely and professional way.

Faulty Receiver Module

Fiat key fobs transmit an alert up 50 feet to the vehicle, which allows it to unlock and lock the doors (and start the vehicle if it has automatic transmissions). There are a variety of reasons why the fob could not function.  G28 Car Keys  include a dead coin battery damaged by water or worn buttons or a problem with the receiver module and signal interference, or an electronic chip that is malfunctioning.

If the fob was placed in a pocket that been subject to extreme trauma, like being dropped on hard floors or being washed in the washing machine, it may not be able to communicate with the car's Body Control Module (BCM). This is because the BCM is secured and will only accept signals from a genuine key and not accept any other.

If this is the case, you will need to replace your fob. A professional locksmith will handle the entire process of replacing your key including programming a new key for your 500. In fact, they can provide you with a duplicate key that functions the same way as your original fob (and costs less than the cost).
