Fiat 500 Replacement Key Fob
It's possible to change the battery if your 500 remote key fob is not working. If you replace the battery, but it's still not working it could be a problem elsewhere.

At United Locksmith, we specialize in making new keys for classic automobiles. We have the tools and parts needed for this job.
Dead Coin Battery
The most frequent reason that your Fiat 500 key fob will not unlock or lock the doors is due to a dead battery. The battery of the coin cell inside the key fob can be depleted quickly in the event that you don't use it often enough. If your remote has started to show signs of loss in range or stopped functioning in the middle of the night, then your battery may be dead.
Metal clips hold the battery in place inside the key fob. If the clips aren't tight enough, they can cause problems with contact, which can prevent your remote from receiving power. Make G28CarKeys of a flathead screwdriver to remove the retaining clip and remove the old battery. Use a battery that has the same voltage, size, and specification as the original.
The exposure to water can cause the key fob to corrode or become damaged. Even a short bath in soapy water could harm the electronic chip in. Keep your key fob dry.
Water Damage
If your key fob isn't operating properly, it may be due to water damage. Key fobs come with rubber seals that stop them from being damaged by light rain or a splash of water. However, it is very important to keep your car keys safe from the pool, ocean, and washing machine!
The key fob comes with an electronic chip that transmits an alert to the immobilizer system in your car. The chip allows the 500 to be locked and started. If it gets wet, however, it will no longer function.
You can try cleaning the internal electronics of your key fob with isopropyl alcohol or an electronic cleaner to determine whether they're still functioning. However, it's better to purchase a replacement from a dealership rather than trying to fix the key fob that has been submerged in salt water.
Although a replacement fob may cost a little money, it's a lot cheaper than paying for your Fiat 500 to be towed to the dealer and repaired! You can also make it yourself by following only a few steps. Just ensure you have the correct battery type before you attempt to open your key fob. This task is much simpler than it appears, and you can find step-by-step directions online for almost any key fob in your car.
Faulty Chip
The chip in the key fob connects directly with the immobiliser on your vehicle to ensure that the vehicle will only start once the proper keys are inserted. If the chip is damaged or damaged the car will not start, no matter what you do.
Damage to the water or a dead battery are the two most common causes of a faulty chip. It is best to hand over the work to a professional locksmith who will be able to replace the chip in a short time and at a an affordable cost.
If your key fob stops functioning after exposure to clean tap water or rain, unplug the battery and wipe down the electronic component with a towel to ensure that it is completely dry before putting it back in. If the key fob still does not work it's most likely to be a damaged chip that must be replaced.
Some people will go to their dealer when they are in need of a new Fiat key fob, but it can be a expensive alternative. If you are looking for a low-cost solution to get your Fiat key fob fixed then look no further than United Locksmith. We have the tools and knowledge necessary to fix your Fiat key fob in a quick and professional way.
Faulty Receiver Module
Fiat key fobs transmit signals up 50 feet to the vehicle, which will open and lock the doors (and start the vehicle in case of automatic transmissions). There are many reasons why the fob might not function. These include a dead coin battery damaged by water buttons, worn ones as well as a receiver module problem and signal interference, or a malfunctioning electronic chip.
If the fob is placed in a pocket that endured extreme trauma, like being dropped on hard floor or getting washed in a washer and it isn't capable of communicating with the car's Body Control Module (BCM). The BCM is a security device that will only accept signals from genuine original keys.
You'll need to replace the fob if this occurs. A professional locksmith will handle the entire replacement process including programming a new key to your 500. They can even provide you with an clone fob that performs just like the original (and costs only one-third of what it would cost).
