Fiat 500 Replacement Key Fob

If your remote key fob has stopped working, it may be time to replace the battery. However, if you replace the battery but it doesn't work the issue could be elsewhere.

United Locksmith specializes in the creation of new keys for classic vehicles. We have the tools and parts required for this type of service.

Dead Coin Battery

A dead battery is the primary cause of your Fiat 500 keyfob not locking or unlocking the doors. The battery for the coin cell in the key fob will drain quickly in the event that you don't use it frequently enough. If your remote starts to show signs like a loss in range or stopped functioning or not responding, then the battery could be dead.

The battery in the key fob is held in place with metal clips that retain it. If the clips are loose it could lead to contact issues, which could prevent your remote from receiving power. Use a flathead screwdriver open the retaining clips and then remove the old battery. Make sure to select an alternative battery that has the same type of voltage, dimensions, and specification as the original battery.

Water exposure can also cause the key fob to become corroded or damaged. Even a short bath in soapy, warm water can damage the chip. It is recommended to keep your key fob in a dry location.

Water Damage

Water damage could be the reason for your key fob's not functioning properly. The rubber seals on key fobs prevent them from being damaged by a small drizzle or splash of water. However, it is crucial to keep your keys of your car away from the washing machine, the ocean, and pool.

The key fob has an electronic chip which sends a message to the immobilizer of your car. The chip is what allows the 500 to be locked and started. If it gets wet, it will no longer function.

If you're looking to determine if your key fob is functional you can clean the internal electronics with isopropyl or an electronic cleaner. However, it is probably recommended to purchase a replacement from a dealership rather than trying to repair an item that has been submerged by salt water.

A replacement fob could cost you a bit, but it's a lot cheaper than having to have your Fiat 500 towed to a dealer and fixed there! You can also make it yourself by following just a few steps. Make sure you have the right battery type before you attempt to open your key fob. This task is far simpler than it appears, and you can find step-by-step instructions online for virtually any key fob for cars.

Faulty Chip

The chip in the key fob communicates directly with the immobiliser of your car to ensure that your vehicle will only start once the proper keys are inserted. If the chip is damaged or corrupted, your car won't start no matter what you do.

Damage to the water or a dead battery are the two most frequent causes of defective chips. Regardless of the reason, it's best to delegate this work to a locksmith, as they can replace the chip for you swiftly and at an affordable price.

If your key fob fails to function after exposure to clean water from the tap or rain, take off the battery and clean the electronic component with a towel to ensure it is fully dry before putting it back into. If the key fob fails to work it's most likely to be a damaged chip that must be replaced.

Some people will go to their dealer if they need an entirely new Fiat fob. However, this can be a costly option. United Locksmith is the best place to go if you need your Fiat key fob repaired at a reasonable price. We have all the tools and knowledge required to fix your Fiat fob in a professional and timely way.

Faulty Receiver Module

Fiat key fobs send signals up 50 feet to the vehicle, which will open and lock the doors (and start the vehicle for those with automatic transmissions). There are a few reasons why a fob could not function. It could be due to a dead battery, water damage buttons, worn ones as well as a receiver module problem and signal interference or an electronic chip that is malfunctioning.

If the fob was in an area that has experienced severe trauma (such as being dropped onto the hard floor or washed in a washing machine) it might not be able to communicate with the Body Control Module (BCM) of the car. This is because the BCM is secured and will only accept a signal from a genuine key and not another.

If this is the case, then you will require replacing your fob. A professional locksmith can handle every aspect of the key replacement process as well as programming a new one for your 500. They can even give you the fob cloned to work exactly like the original (and costs only one-third of the price).
