Dead Coin Battery

The most common reason why your Fiat 500 key fob will not lock or unlock the doors is due to a dead battery. The battery of the coin cell inside the key fob can be depleted quickly if you don't use it frequently enough. If your remote starts to show signs like a loss of range, or has stopped functioning and the battery is not working, it could be dead.

Metal clips keep the battery in within the key fob. If the clips aren't secure, they could cause problems with contact that can prevent your remote to receive power. With a small flathead screwdriver, push the retaining clip outwards to remove the battery and then insert a fresh one. Be sure to choose a replacement with the same type of voltage, size and specifications as the original battery.

The key fob may also be damaged or corroded through exposure to water. Even a quick bath in soapy water may damage the electronic chip inside. Make sure your key fob is dry.

Water Damage

If your key fob doesn't work properly, it may be due to water damage. Key fobs have rubber seals that stop them from being damaged by light rain or splashes of water, however it is crucial to keep your car keys out of the ocean, pool, and the washing machine!

The key fob is equipped with an electronic chip that transmits an alert to the immobilizer system in your car. This is what allows your 500 to start or lock, but when the chip becomes wet, it will no longer work.

If you're interested in checking whether your key fob functional it is possible to clean the internal electronics using isopropyl or electronic cleaner. However, it's recommended to purchase a replacement from a dealer instead of trying to repair an item that has been submerged in salt water.

While a replacement fob could cost a little money, it's much cheaper than having to pay for your Fiat 500 to be towed to the dealer and repaired! Plus, you can do it yourself with only a few steps. Be sure to have the correct battery type before you attempt to open your key fob. This task is more straightforward than it appears and you can find step-by-step directions on the internet for nearly any car key fob.

Faulty Chip

The chip in the key fob communicates with the immobiliser on your vehicle to ensure that the vehicle will only start once the proper keys are inserted. If the chip is damaged, or damaged in any way the car won't start.

Damage to the water or a dead cell phone battery are among the most frequently cited reasons for an unreliable chip. It is best to leave the work to a professional locksmith, who can repair the chip quickly and at an affordable cost.

If your key fob stops working after exposure to clean tap water or rain, take out the battery and wipe down the electronic component with a paper towel to ensure that it is completely dry before putting it back into. If the key fob does not work, there is the possibility that it has a fried component and needs to be replaced.

Some people go to their dealer when they require a new Fiat fob. However, this could be costly. If you are looking for a cost-effective way to have your Fiat key fob fixed make sure you contact United Locksmith.

Faulty Receiver Module

Fiat key fobs transmit a signal to the vehicle that will unlock and close doors (and start the car if it has an automatic transmission) up to 50 feet. There are many reasons why the fob could stop working. It could be due to a dead battery water damage, worn buttons and a receiver module issue, and signal interference or an electronic chip malfunctioning.

If the fob was stored in a place that has been subject to extreme trauma, like falling on hard floor or being washed in a wash machine, it may not be capable of communicating with the car's Body Control Module (BCM). This is because the BCM is a secure system that will only accept a signal from a genuine key and not any other.

You'll have to replace the fob in case this happens. A professional locksmith will take care of the entire process of replacing keys including programming a new one for your 500. In fact, they'll offer you a clone key that functions exactly like your original fob (and costs a fraction of the cost).
