Fiat 500 Replacement Key Fob

It may be time to replace the battery if your 500 remote key fob isn't working. If you replace the battery, but it still doesn't work, the problem may be elsewhere.

At United Locksmith, we specialize in the creation of new keys for old automobiles. We have the tools and parts required for this type of service.

Dead Coin Battery

A dead battery is the most frequent reason for your Fiat 500 keyfob not locking or unlocking the doors. The key fob is equipped with a coin cell battery which will quickly drain when it isn't being used often enough. If your remote has started to show signs of a loss of range or has stopped functioning, then the battery may be dead.

Metal clips keep the battery in place inside the key fob. If the clips are loose it can cause contact issues, which could prevent your remote from receiving power. By using a small flathead screwdriver, push the clip that holds the retaining pin open to remove the current battery and then insert a fresh one. Be sure to use an identical replacement battery kind of voltage, size and specifications as the original battery.

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

Water Damage

Damage to your water supply could be the reason for your key fob not working properly. Key fobs come with rubber seals that protect them from being damaged by light rain or a splash of water, however it is very important to keep your keys out of the pool, ocean, and washing machine!

The key fob has an electronic chip that sends an alert to the immobilizer of your car. The chip allows the 500 to be locked and started. If it gets wet it won't work.

Try cleaning your key fob's internal electronics with isopropyl Alcohol or an electronic cleaner to determine if they are still good. It is best to replace the key fob if it's submerged into salt water, rather than trying to fix it yourself.

While a replacement fob can cost a bit of money, it's far less expensive than paying for your Fiat 500 to be towed to a dealership and fixed! Plus, you can make it yourself in just the simplest of steps. Be sure to have the correct type of battery before attempting to open your key fob. You can find step-bystep instructions for any car keyfob online.

Faulty Chip





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

A damaged chip could occur due to many reasons, but most often it is due to water damage or an unresponsive battery. It is best to delegate the job to a professional locksmith who can repair the chip in a short time and at a an affordable price.

If your key fob will not function after exposure to clean water from a tap or rain, remove the battery. Wipe down the electronic component with paper towels. If the key fob does not work it's probably to be a damaged chip that is required to be replaced.

Some people will go to their dealer when they require an entirely new Fiat fob. However, G28CarKeys can be expensive. If you are seeking a cost-effective method to have your Fiat key fob repaired make sure you contact United Locksmith. We have all the tools and experience needed to repair your Fiat fob in a professional and timely way.

Faulty Receiver Module

Fiat key fobs send signals of up 50 feet to the vehicle, which can unlock and close the doors (and start the vehicle in case of automatic transmissions). However there are a few things that could cause the fob to cease functioning. It could be due to a dead battery, water damage buttons, worn ones, a receiver module issue and signal interference or an electronic chip that has failed.

If the fob is stored in a place that has endured extreme trauma, such as falling on hard floor or being washed in the washing machine the fob may not be able to communicate with the car's Body Control Module (BCM). This is because the BCM is secured and will only accept signals from a genuine original key, and not from any other.

If this is the case, then you will require replacing your fob. A professional locksmith can handle all aspects of the replacement procedure and even program a new one for your 500. In fact, they could provide you with a duplicate key that works just the same as the original fob (and costs a fraction of the price).
