fiat car key cutting

If your 500 remote key fob isn't working, it might be time to replace the battery. However, if you replace the battery and it is still not working, then the problem may be elsewhere.

At United Locksmith, we specialize in the creation of new keys for old automobiles. We have all of the tools and components needed to perform this service.





Dead Coin Battery

A dead battery is the primary cause of your Fiat 500 keyfob not locking or unlocking the doors. The key fob is equipped with an in-built battery that will drain quickly in the event that it is not utilized frequently enough. If your remote starts to show signs of loss of range or stopped working, then the battery may be dead.

Metal clips hold the battery in place inside the key fob. If the clips are not secure, they could cause problems with the contact, which can stop the remote from receiving power. Using a small flathead screwdriver, pry the retaining clip to remove the battery, and replace it with a brand new one. Be sure to use an alternative battery that has the same kind of voltage, size and specifications as the original battery.

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

Water Damage

If your key fob isn't functioning correctly, it could be due to water damage. Key fobs have rubber seals that prevent them from being damaged by light rain or splashes of water. However, it is essential to keep your car keys away from the pool, ocean and washing machine!

The key fob comes with an electronic chip that sends a signal to your car's immobilizer system. This is what allows your 500 to start or lock, but when the chip becomes wet, it's unable to 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. It is recommended to replace the key fob when it's submerged into salt water rather than try to fix it yourself.

A replacement fob may cost you a bit, but it's a lot cheaper than having to have your Fiat 500 towed to a dealership and repaired there! Plus, you can make it yourself in just several easy steps. Make sure you have the correct battery type before attempting to open your key fob. You can find step-bystep instructions for any car keyfob online.

Faulty Chip

The chip in the key fob communicates with the immobiliser in your car to ensure that your vehicle will only start when the correct keys are used. If the chip is damaged, or corrupted in any way it will not start.

Water damage or a dead cell phone battery are the most common reasons for an unreliable chip. Regardless of the reason, it's recommended to delegate the job to a locksmith, as they will be able to repair the chip for you quickly and at a reasonable cost.

If your key fob will not work after exposure to clean rain or tap water, remove the battery. Wipe down the electronic component using an old towel. If the key fob still isn't working it's likely to be a fried chip and will require replacement.

A few people turn to their dealer when they are in need of an entirely new Fiat key fob, but it can be a expensive alternative. United Locksmith is the best option if you would like to have your Fiat keyfob fixed at a reasonable price. We have the equipment and know-how required to repair your Fiat key fob in a timely and professional manner.

Faulty Receiver Module

Fiat key fobs send an electrical signal to the vehicle that will unlock and close doors (and start the car for those with an automatic transmission) up to 50 feet. There are many reasons why the fob might not function. This includes a dead coin-battery water damage, worn out buttons or a receiver issue signal interference or a malfunctioning chip.

If the fob has been stored in a place that has endured extreme trauma, like being dropped on hard floor or being washed in the washing machine or dishwasher, it might not be able to communicate with the car's Body Control Module (BCM). The BCM is a security system which will only accept signals from genuine original keys.

You'll need to replace the fob in case this occurs. A professional locksmith can handle all aspects of the replacement procedure and even program a new one for the 500. In fact, they'll provide you with a clone key that functions exactly like the original fob (and costs less than the cost).
