Fiat 500 Replacement Key Fob
If your 500 remote key fob has stopped functioning, it could be time to replace the battery. If you do replace the battery but it does not work then the issue may be elsewhere.
At United Locksmith, we specialize in the creation of new keys for old cars. 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 key fob contains an internal battery called a coin cell that can quickly deplete in the event that it is not utilized frequently enough. If your remote has started to show signs of loss in range or stopped working in the middle of the night, then your battery may be dead.
The battery in the key fob is held in place by metal clips that retain it. If the clips aren't secure, they could cause contact issues that prevent the remote from receiving power. Use a flathead screwdriver to open the retaining clips and remove the battery. Make sure that the battery you choose to use has the same size, voltage and specification as the original.
Water exposure can cause the key fob to become corroded or damaged. Even replacement fiat key fob in soapy water can harm the electronic chip in. It is recommended to keep your key fob in a dry place.
Water Damage
If your key fob isn't working properly, it could be caused by water damage. Key fobs are fitted with rubber seals to protect them from being damaged by a light rain or splashes of water, however it is crucial to keep your keys out of the pool, ocean and washing machine!
The key fob contains an electronic chip in it that sends a signal car's immobilizer system. The chip allows the 500 to start and lock. If it gets wet it won't function.
If you're trying to determine whether your key fob still functioning it is possible to clean the internal electronics with isopropyl or an electronic cleaner. However, it's better to purchase a replacement from a dealership rather than trying to fix the key fob that has been submerged by salt water.
While a replacement fob can cost a bit of money, it is far less expensive than having to pay for your Fiat 500 to be towed to a dealership and fixed! Plus, you can do it yourself with the simplest of steps. Be sure to have the correct type of battery prior to opening your keyfob. You can find step-by-step instructions for every car keyfob online.
Faulty Chip
The chip inside the key fob connects directly with the immobiliser on your vehicle to ensure that the vehicle will only start once the correct keys are used. If the chip is damaged, or damaged in any way the car won't start.
A damaged chip could occur due to a variety of reasons, but the most common cause is water damage or a dead battery. It is best to hand over the job to a professional locksmith, who can replace the chip in a short time and at a reasonable cost.
If your key fob fails to function after exposure to clean tap water or rain, take off the battery and clean the electronic component using a paper towel to ensure it's dry before putting it back into. If the key fob still fails to work it's most likely to be a damaged chip that will require replacement.
Some people will go to their dealer if they need an entirely new Fiat fob. However, this could be a costly option. United Locksmith is the best place to go if you are looking to have your Fiat keyfob fixed at a reasonable cost. We have all the tools and expertise to fix your Fiat fob in a professional and timely way.
Faulty Receiver Module
Fiat key fobs transmit an electrical signal to the vehicle that will unlock and close doors (and start the car if it has an automatic transmission) up to 50 feet. There are several reasons why the fob may stop working. This could be due to a dead coin battery or water damage, worn buttons and a receiver module issue, and signal interference or an electronic chip that has failed.
If the fob is in the pocket that has been subject to severe trauma (such as being dropped on the hard floor or washed in the washer) it might not be able to connect with the Body Control Module (BCM) of the car. The BCM is a security device that only accepts signals from genuine keys.
You'll need to replace the fob if this occurs. A professional locksmith can handle the entire replacement process including programming a brand new key for your 500. They can even provide you with an clone fob that performs the same as the original (and costs less than the price).
