Dead Coin Battery

The most frequent reason that your Fiat 500 key fob will not unlock or lock the doors is a dead battery. The key fob comes with an in-built battery that can quickly deplete if it is not used often enough. If your remote began to show signs of weakening such as a loss of range, and then stopped working completely The battery is probably dead.

The battery in the key fob is held in place by metal retaining clips. If the clips are not secure, they could cause problems with the contact, which can stop your remote from receiving power. By using a small flathead screwdriver, push the retaining clip to take out the battery, and replace it with a brand new one. Be sure to use an alternative battery that has the same type of voltage, dimensions and specifications as the original battery.

The key fob could also become corroded or damaged due to exposure to water. Even a brief bath in soapy, warm water can cause damage to the chip. Make sure your key fob is dry.

Water Damage





If your key fob isn't functioning properly, it may be due to water damage. Key fobs have rubber seals that prevent them from being damaged by a light rain or splashes of water, however it is vital to keep your keys safe from the ocean, pool, and the washing machine!

The key fob contains an electronic chip that sends an immobilizer of your car. The chip is what allows the 500 to lock and start. If it gets wet it will cease to work.

This task is much easier than it looks and there are step-by-step instructions on the internet for nearly any car key fob.

Faulty Chip

The chip located within the key fob communicates to your car's immobiliser unit to ensure the car is able to start when the correct key is used. If the chip is damaged or damaged, your car won't start regardless of what you do.

A damaged chip could occur due to a variety of reasons but the most common cause is water damage or an unresponsive battery. Whatever the reason, it's best to delegate the work to a locksmith, as they will be able to repair the chip fast and at a low cost.

If your key fob will not work after exposure to clean tap or rain water then remove the battery. Clean the electronic component with paper towels. If the key fob does not function, there's the possibility that it has a fried component and needs to be replaced.

Faulty Receiver Module
