United fiat car keys specializes in the creation of new keys for classic cars. We have the tools and spare parts needed for this job.
Dead Coin Battery
A dead battery is the most common reason for your Fiat 500 keyfob not locking or unlocking the doors. The battery of the coin cell inside the key fob is likely to drain quickly when you don't utilize frequently enough. If your remote has started to show signs of a loss of range or stopped working, then the battery may be dead.
The battery inside the key fob is held in place by steel clips for retaining. If the clips are loose they could cause contact issues which will prevent your remote from receiving power. Utilizing a small screwdriver, push the retaining clip to remove the current battery and replace it with a new one. Be sure to use an alternative battery that has the same type of voltage, size and specifications as the original battery.
Water exposure can also cause the key fob to corrode or be damaged. Even a small shower in soapy water can damage the electronic chip inside. It is best to keep your key fob in a dry environment.
Water Damage
Damage to your water supply could be the reason behind your key fob not working properly. The rubber seals on key fobs prevent them from being damaged by a light splash or drizzle of water. However, it is essential to keep the keys of your car away from the washing machine, ocean, and the pool.
The key fob is equipped with an electronic chip that transmits an electronic message to the immobilizer system of your car. The chip allows the 500 to start and lock. If it gets wet, however, it will no longer function.
If you're looking to determine if your key fob is functional it is possible to clean the internal electronics with isopropyl or an electronic cleaner. However, it is probably best to get a replacement from a dealership rather than trying to repair an item that was submerged in salt water.
Although a replacement fob may cost a little money, it's much cheaper than paying for your Fiat 500 to be towed to the dealership and repaired! Plus, you can do it yourself in several easy steps. Be sure to have the correct type of battery before attempting to open your key fob. There are step-by-step directions for any car keyfob on the internet.
Faulty Chip
The chip inside the key fob communicates with the vehicle's immobiliser to ensure that the vehicle is only capable of starting when the correct key is used. If the chip is damaged or corrupted the car will not start no matter what you do.
Water damage or a dead cell phone battery are the most common reasons for defective chips. Regardless of the reason, it's an ideal idea to hand this work to a locksmith, as they will be able to replace the chip for you quickly and at a cost-effective price.
If your key fob stops functioning after exposure to clean water from the tap or rain, take off the battery and wipe down the electronic component with a paper towel to ensure it's dry before putting it back into. If the key fob still fails to work it's probably an issue with the chip and must be replaced.
Some people will go to their dealer when they are in need of an entirely new Fiat key fob, however this is a costly alternative. If you're seeking a cost-effective method to get your Fiat key fob repaired Look no further than United Locksmith. We have the equipment and know-how needed to repair your Fiat key fob in a quick and professional way.
Faulty Receiver Module

Fiat key fobs transmit an alert up to 50 feet to the vehicle, which will unlock and close the doors (and start the vehicle in case of automatic transmissions). However, there are some things that could cause the fob to stop working. This includes a dead coin-battery water damage, worn-out buttons an issue with the receiver, signal interference or a malfunctioning chip.
If the fob was located in a pocket which has suffered severe trauma (such as being dropped onto a hard floor or being washed in the washing machine) the fob may not be in a position to connect with the Body Control Module (BCM) of the vehicle. This is because the BCM is a secure system that will only accept a signal from a genuine key and not any other.
It is necessary to replace the fob if this occurs. A professional locksmith can handle all aspects of the replacement process, including programming a new one for the 500. In fact, they can even provide you with a duplicate key that works just like your original fob (and costs a fraction of the cost).
