Remotes
The remote controls on Fiat vehicles are similar to the keys, but they feature an IR (infrared) LED at the bottom. This LED sends an electronic signal to the device which allows the vehicle to open or start when the button is pressed. The microprocessor in the key converts the signal into a code which is then sent to the device.
This is known as "keyless entry". The more modern your car is, and the more likely it is that you have the keyless system. The more advanced your vehicle is, the more features it will come with. This includes locking and unlocking your car with just a push of a button or opening the doors without touching the handle, and much more.
The key fob comes with an integrated circuit chip that communicates with the immobiliser system of the car. The system determines whether the key is genuine by checking a specific sequence within the transponder. The vehicle will not start when the chip isn't present or when it's not programmed with the correct immobiliser system.
A locksmith can replace the key fob if it is damaged. They will also have to program the replacement key to connect with the car's immobiliser system. This is an important part of the procedure, and you must be ready to provide information about your vehicle to your locksmith when they call you.
Keyless Entry
If you have a keyless entry system on your Fiat 500, you can lock and unlock the car at any time with the push of a button. This technology is becoming more prevalent in vehicles of all ages and models and can add convenience and safety to your vehicle's use.
Verify that your remote keyless entry system is not working. The battery inside the fob might be dead. If the battery has been drained, replace it with a new one that is of the same voltage, size, and type as the original. You should also ensure that the battery's contacts are free of corrosion or dust.
The rubber seals on the key fob are designed to protect the electronic chip from water. However long-term exposure to salty or soapy water can cause the chip to fail. If your key fob is exposed to water, take out the battery and allow it to dry completely before putting it back into. You can also try cleaning the electronic chip using isopropyl ethanol or electronic cleaner.
The keyless entry system is more secure than traditional systems, because it generates the code used to unlock your car after each use. This means that even if hackers intercept the signal and attempt to access your car, they won't be able to gain permanent access to your car.
Transponders
Fiat uses a crypto key transponder system. This means that the keys/transponders have to be encoded with a secret code by the Body Control Module (BCM) before being "programmed" into the BCM. This is why a blank unwritten key is not able to be programmed, because the BCM has to read & write it's secret key to the transponder & lock it. This is known as the cloning.
