Dead Coin Battery

A dead battery is the primary reason for your Fiat 500 keyfob not locking or unlocking the doors. The key fob is equipped with an internal battery called a coin cell that will drain quickly when it isn't frequently used. If your remote has started to show signs of loss of range, or has stopped working or not responding, then the battery could be dead.

Metal clips keep the battery securely in the key fob. If the clips aren't tight, they can cause problems with contact that can prevent the remote from receiving power. Utilizing a small screwdriver, pry the retaining clip to remove the battery and insert a new one. Be sure to choose an identical replacement battery type of voltage, dimensions and specifications as the original battery.

Water exposure can cause the key fob to corrode or become damaged. Even a quick bath in warm, soapy water could cause damage to the chip. It's best to keep your key fob in a dry location.

Water Damage

If your key fob isn't working properly, it may be caused by water damage. The rubber seals on key fobs stop them from getting damaged by a slight splash or drizzle of water. However, it's crucial to keep your car keys away from the washing machine, the ocean and pool.

The key fob comes with an electronic chip in it that transmits a signal car's immobilizer system. The chip allows the 500 to lock and start. If it gets wet it will not function.

If you're interested in checking whether your key fob functioning you can clean the internal electronics using isopropyl or an electronic cleaner. It is recommended to replace a key fob if it's submerged in salt water rather than attempting to fix it yourself.

Faulty Chip

The chip located within the key fob communicates to your car's immobiliser unit to ensure the vehicle is only able to start when the correct key is inserted. If the chip is damaged, or damaged in any way, your car will not start.

A faulty chip can occur due to many reasons, but most commonly due to water damage or the battery being dead. Regardless of the reason, it is recommended to delegate the job to a locksmith as they will be able to replace the chip for you quickly and at an affordable price.

If your key fob will not function after being exposed to water that is clean from the tap or rain, remove the battery. Clean the electronic component with an old towel. If the key fob will not work, there's the possibility that it's malfunctioning components and need to be replaced.

Faulty Receiver Module

Fiat key fobs transmit signals up 50 feet away to the vehicle, which will open and lock the doors (and start the vehicle for vehicles with automatic transmissions). However, there are a few factors that could cause the fob to stop functioning. This can be caused by a dead coin-battery water damage, worn-out buttons, a receiver issue, signal interference, or malfunctioning chips.

If the fob is in a pocket that has been subject to extreme trauma, like being dropped on hard floors or getting washed in a wash machine or dishwasher, it might not be capable of communicating with the car's Body Control Module (BCM). The BCM is a security device which will only accept signals from genuine original keys.

You'll need to replace the fob if this occurs. A locksmith professional can handle all aspects of the replacement procedure, including programming a new one for the 500. They can even provide you with the fob cloned to work just like the original (and costs only a fraction of the price).
