Fiat 500 Replacement Key Fob
If your 500 remote key fob has stopped working, it's time to replace the battery. If you replace the battery but it still doesn't work the issue could be elsewhere.
At United Locksmith, we specialize in making new keys for classic automobiles. We have the tools and components needed for this service.
Dead Coin Battery
A dead battery is the main reason for your Fiat 500 keyfob not locking or unlocking the doors. The key fob has an internal battery called a coin cell that will drain quickly if it is not used often enough. If your remote has started to show signs like a loss of range or has stopped working or not responding, then the battery could be dead.
Metal clips keep the battery in place within the key fob. If the clips aren't tight enough, they could cause contact issues which will prevent your remote from receiving power. With a small flathead screwdriver, push the clip that holds the retaining pin open to remove the battery and replace it with a new one. Use a battery that has the same voltage, size and specification as the original.
The key fob might be damaged or corroded by water exposure. Even a small shower in soapy water can harm the electronic chip in. It's best to keep your key fob in a dry area.
Water Damage
If your key fob doesn't work properly, it may be caused by water damage. The rubber seals on key fobs stop them from getting damaged by a small drizzle or splash of water. However, it's important to keep the car keys away from the ocean, washing machine, and even the pool.
The key fob comes with an electronic chip inside that transmits a signal car's immobilizer system. This is the reason why your 500 can start or lock, however when the chip becomes wet, it will no longer function.
If you're interested in checking if your key fob is functioning it is possible to clean the internal electronics with isopropyl or electronic cleaner. However, it's better to purchase a new one from a dealership instead of trying to repair a key fob that has been submerged by salt water.
A replacement fob might cost you some money, but it's a lot cheaper than having to have your Fiat 500 towed to a dealership and fixed there! You can also fix it yourself with some simple steps. Make sure you 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 that is contained in the key fob communicates with your car's immobiliser unit to ensure the vehicle is able to start when the correct key is inserted. If the chip is damaged or damaged in any way, your car will not start.
Water damage or a dead cell phone battery are the most common reasons for the chip being damaged. Regardless of the reason, it's best to delegate this work to a locksmith who will be able to repair the chip for you swiftly and at a low cost.
If G28CarKeys ceases to function after exposure to clean tap water or rain, remove the battery and wipe down the electronic component using a paper towel to ensure it's completely dry before putting it back into. If the key fob does not function, there is an opportunity that it is malfunctioning components and need to be replaced.
Some people will go to their dealer if they need an entirely new Fiat fob. But, this can be a costly option. United Locksmith is the best place to go if you need your Fiat keyfob repaired at a reasonable price. We have the tools and knowledge required to fix your Fiat fob in a professional and timely manner.
Faulty Receiver Module
Fiat key fobs transmit signals up 50 feet to the vehicle, which will unlock and close the doors (and start the vehicle for vehicles with automatic transmissions). There are several reasons why the fob could stop working. These include a dead coin battery, water damage or worn buttons and a receiver module issue or signal interference, or an electronic chip malfunctioning.
If the fob was located in the pocket that has been subject to severe trauma (such as being dropped onto the floor or washed in a washing machine) the fob might not be in a position to connect with the Body Control Module (BCM) of the vehicle. This is because the BCM is an extremely secure system that will only accept signals from a genuine key and not accept any other.
You'll need to replace the fob if this happens. A professional locksmith will manage the entire process of replacing keys including programming a brand new key for your 500. They can even give you a clone fob that works exactly the same way as the original (and costs one-third of the cost).
