Dead Coin Battery

The most common reason your Fiat 500 key fob will not unlock or lock the doors is due to a dead battery. The key fob has a coin cell battery which will quickly drain in the event that it is not frequented enough. If your remote starts to show signs of loss of range, or has stopped functioning, then the battery may be dead.

The battery in the key fob is held in place by metal clips that retain it. If the clips aren't secure, it can cause contact issues which will prevent the remote from receiving power. Use a flathead screwdriver break open the retaining clip and remove the old battery. Be sure to use an alternative battery that has the same kind of voltage, size, and specification as the original battery.

The key fob could be damaged or corroded through exposure to water. Even a quick bath in soapy, warm water can cause damage to the chip. It is best to keep your key fob in a dry location.

Water Damage

Water damage may be the reason for your key fob's not functioning properly. The rubber seals on key fobs stop them from getting damaged by a slight drizzle or splash of water. However, it's essential to keep the keys from the washing machine, the ocean and the pool.

The key fob comes with an electronic chip which sends an electronic message to the immobilizer of your car. The chip is what allows the 500 to lock and start. If it gets wet, however it will cease to work.

You can try cleaning the inside of your key fob's electronics with isopropyl alcohol or an electronic cleaner to see whether they're still working. However, it is probably better to purchase a replacement from a dealer rather than trying to repair an item that has been submerged in salt water.

While a replacement fob could cost a bit of money, it is much cheaper than having to pay for your Fiat 500 to be towed to the dealer for repair! In addition, you can make it yourself in just a few easy steps. Make sure you have the correct type of battery prior to opening your key fob. This is a job that's far simpler than it appears, and there are step-by-step instructions on the internet for nearly any key fob in your car.

Faulty Chip

The chip located within the key fob communicates with your car's immobiliser unit to make sure your car is only capable of starting when the correct key is used. If the chip is damaged or destroyed the car won't start no matter what you do.

A chip that is damaged can happen due to many reasons, but most often it is due to water damage or an unresponsive battery. It is recommended to leave the task to a professional locksmith, who can repair the chip in a short time and at a a reasonable price.

If your key fob stops working after exposure to clean tap water or rain, remove the battery and wipe down the electronic component with a tissue to ensure it is fully dry before putting it back in. If the key fob still does not work it's probably to be a damaged chip that will need to be replaced.

Faulty Receiver Module

Fiat key fobs transmit an alert up 50 feet away to the vehicle, which can unlock and close the doors (and start the vehicle if it has automatic transmissions). There are a variety of reasons why the fob might stop working. This includes a dead coin-battery water damage, worn-out buttons or a receiver issue signal interference or an issue with the chip.

If the fob is in a pocket which has endured extreme trauma, like falling on hard floor or getting washed in a wash machine the fob may not be capable of communicating with the car's Body Control Module (BCM). This is because the BCM is an extremely secure system that will only accept signals from a genuine key and not any other.

It is necessary to replace the fob if this happens. A locksmith professional can handle all aspects of the key replacement process as well as programming a new one for the 500. In fact, they can provide you with a replica key that functions exactly the same as the original fob (and costs only a fraction of the cost).
